I'm kinda stuck
where is the yashiro guy
soft jetty
what is the error?
sick haven
what is the error?
soft jetty
Okay, so what does that error mean?
soft jetty
okay did the tutorial show some code? because the way you've written the code it seems like you didn't follow the tutorial exactly
i might double check there first, or I can explain what's going wrong
sick haven
like
I watched a bunch of vids
and none of them is really helping
so I'm trying to kinda figure it out by myself
soft jetty
and none of them is really helping
helping with...?
sick haven
solving the convert problem
soft jetty
maybe you could structure your code more off the tutorials
the convert function contains an out parameter, you could learn more about this to fix your code
sick haven
what
soft jetty
okay I'll try to explain what's going on
first what is strange about your code is that you are assigning a variable inside the condition part of the if statement
do you see the code I am talking about?
sick haven
yep
soft jetty
what was your thought process for doing this?
sick haven
but it doesn't work that way
that's why i put it in there
It didin't work the other way
soft jetty
Could you explain more about the different ways you tried? Remember, coding shouldn't be guessing things
sick haven
eh
sick haven
Could you explain more about the different ways you tried? Remember, coding shou...
it is when you're beggining
soft jetty
it is when you're beggining
I can understand why you might be tempted to guess, since it can be hard to find the right code. But in the long run it's much more useful to learn why things are correct instead of guessing
anyways, going back to the if statement, what normally goes inside the parentheses?
sick haven
nope
soft jetty
okay good
now read the parse function and tell me what it returns. do you know about functions and what they return?
sick haven
they return a variable
soft jetty
yes, and in this case, what is the type of the variable?
sick haven
int
soft jetty
are you sure? did you read the function description?
soft jetty
yeah so does your error make more sense now?
What is the meaning of that return value? Like if the parse function returned false what does that mean?
sick haven
it didin't convert
soft jetty
it wasn't successful, yeah. and true means the conversion (or parsing) was successful
sick haven
exactly
soft jetty
So knowing this, how might you rewrite some of your code
And maybe you have other questions now about how this parse function works if it doesn't return an int
soft jetty
can you elaborate?
sick haven
I was trying to change it so the tryparse will be above the if statement
soft jetty
Okay show me what you've got
It's okay if it has errors, we'll work through it together
sick haven
soft jetty
okay that's a start. remind me what type the parse function returns?
sick haven
bool
soft jetty
maybe you see a problem?
sick haven
soft jetty
okay I think you are confusing something
the return value of the function is what the overall function "becomes"
like you can imagine replacing the entire function with its return value.
so for example, if the parse was successful, you might get
int guess = int.TryParse(...) would "become" int guess = true
does this make sense?
soft jetty
like if I had a function that looked like
int Add(int a, int b)
{
return a + b;
}
int c = Add(1, 2);
// you could think about it like:
int c = 3; // so because Add(1, 2) returns 3, you can imagine that the entire function call Add(1, 2) was replaced with 3
you could imagine that the Add(1, 2) was replaced with its return value, which is 3
it doesn't actually happen this way, but it might be useful to think about it this way
what part are you confused about?
sick haven
like if I had a function that looked like
```cs
int Add(int a, int b)
{
retu...
yeah
get it
soft jetty
so why is what you did here not correct? i see you did change a type from int to bool...
sick haven
okay great!
like this what you wrote
sick haven
I get that you can replace an entire method with just smth smaller
soft jetty
okay. the point i was trying to illustrate it that a function can be "replaced" by its return value
sick haven
but the return value is int the function
soft jetty
sick haven
bro that shit is so confusing
soft jetty
don't worry about the parsed int value yet. just work on using the true false return value to indicate success or failure
sick haven
alr
soft jetty
i mean, ask any questions you have and ill see if i haven't thought of them or if we will get to them later
if you want to continue, modify the code to take into account the return type of the parse method
soft jetty
so right now you've written int guess = int.TryParse(...). why is this wrong?
sick haven
this is wrong?
soft jetty
haha we just went over this. the int.TryParse function returns a bool, meaning true or false.
so when the function returns this bool, it tries to assign the value to guess, but guess is an int
right? like int guess = true or int guess = false
which is not allowed because the types do not match
soft jetty
how about creating a new variable? the return value doesn't represent your guess, it represents whether the function succeeded, right?
sick haven
yhm
soft jetty
go ahead and post the new code
soft jetty
okay LOL
soft jetty
haha I'll be frre again in like 3 hrs
maybe someone else can pick up where we left off
or you can wait!
sick haven
anybody there to help?

void steppe
I see conversation has already happened here
sick haven
yyea
sick haven
so
I'm trying to use the tryparse method for the first time
and it was not really working
void steppe
"not working" how?
hidden juniperBOT
"It's not working" is not helpful
In order for a question to be answered, it must specify what exactly is wrong. Stating simply that "it doesn't work" is not sufficient.
Source: https://idownvotedbecau.se/itsnotworking
Please elaborate on your question by including all relevant details. What do you think is the problem? Have you tried to fix it? If you have, why didn't that work?
sick haven
"not working" how?
like for me
I watched like a bunch of tutorials
and none of them has helped me
so I asked here for help
and've been kinda stuck at the bool part of try parse
wait
I'll send you what we are working with
void steppe
That's fine I can still explain how TryParse works, if you need that

}```I quickly recreated it
void steppe
Okay. So first question: do you know what type is returned by TryParse?
sick haven
bool
void steppe
Correct. So why do you store the result in an int?
int guess = int.TryParse(...
// ^ why this?
It should
sick haven
okay
void steppe
TryParse returns true if the conversion was successful, false otherwise
This is how you check if the user entered a valid integer
void steppe
Okay next problem, you're missing semicolons
Which your IDE is crying out about to you
sick haven
I didin't think you use them here
void steppe
Okay cool
I see you also fixed the = to ==
That was going to be my next point
But actually, it is redundant here. A condition is compared against true anyway
void steppe
When you write if (condition), what this actually means is "is condition true?" This means you can just write if (guess), because that checks if guess is true.
When you write if (guess == true), this is like a much more verbose question, "is the claim that guess is equal to true, a true claim?" which - while technically results in the same output - is needlessly wasteful
sick haven
When you write `if (condition)`, what this actually means is "is `condition` tru...
okay
didin't know that
void steppe
The same applies to while loops
You have while (guess <= 0) (let's just ignore the >10 one for now). This is asking "is the claim that guess being less than or equal to 0, a true claim?"
You don't write == true here, despite the fact that you could. You could write while (guess <= 0 == true). Which just extends the question to something like "is the assertion that guess being less than or equal to 0 is a fact, a true assertion?"
But no one does that because it's stupid 
You can chain any amount of == true to the end, and the logic holds. if (guess == true == true == true == true)
But it's pointless because you're just asking the same question again and again
void steppe
Anyway, next problem: your while loop
guess is defined to be of type bool, which means it's either true or false. So you can't check if it's between 1 and 10, because true/false isn't a number between 1 and 10
void steppe
I think what you meant to write on line 5 is ..., out int guess); - this stores the converted integer into guess. And the bool itself should be called something else
sick haven
don't know what exactly
void steppe
Because your code above shows you using guess in the printNumber method, with the assumption that it's an int
sick haven
I think what you meant to write on line 5 is `..., out int guess);` - this store...
uuu
sick haven
I think what you meant to write on line 5 is `..., out int guess);` - this store...
that was deep
void steppe
An example of how TryParse is to be used:
Console.Write("Enter a number: ");
string input = Console.ReadLine();
bool success = int.TryParse(input, out int number);
if (success)
{
Console.WriteLine($"You entered a number, and it was {number}.");
}
else
{
Console.WriteLine("You did not enter a number");
}
Or alternatively, because success is only used in the if statement, you can just call it as the condition:
Console.Write("Enter a number: ");
string input = Console.ReadLine();
if (int.TryParse(input, out int number))
{
Console.WriteLine($"You entered a number, and it was {number}.");
}
else
{
Console.WriteLine("You did not enter a number");
}
I think I should change the guess in if statement to "statement"
void steppe
Yes, though statement is a weird name
sick haven
An example of how `TryParse` is to be used:
```cs
Console.Write("Enter a number:...
what is that dollar sign
void steppe
I had a feeling you'd ask about that
soft jetty
Smh complicating everything
void steppe
what is that dollar sign
It's called string interpolation. It allows you to use variables in the string by surrounding them with { }, like you see it has {number}
$"You entered a number, and it was {number}."
is more or less the same as
"You entered a number, and it was " + number + "."
except the latter is a shit way to do it and shouldn't be used
void steppe
Yes you should always use interpolation wherever possible
Which is like 98% of cases. In the other cases, you can use string.Format or StringBuilder
but don't worry about those for now
void steppe
okay
Same situation here, you're storing the result in an int guess and declaring a num, when it should store to a bool and write to guess
void steppe
you don't need to create a new bool, just use the one you already have
void steppe
Because you're not spelling it correctly
void steppe
and as for the error on guess, that's because you're trying to redeclare a new variable with the name guess
Instead of out int x, to write to an existing variable you just do out x
void steppe
You're welcome I guess
Now you just need to use success to print a message or whatever if the user enters anything except a number
But looks like you know how to do that already
sick haven
I appreciate that🙏
void steppe
(Hint: x == false is also redundant. You can just write !x)
sick haven
But looks like you know how to do that already
I've got one more question
Console.WriteLine("You need to get the number in under 10 tries then you win, if not you lose!");
Console.Write("Pick a number between 1 and 10: ");
bool success = int.TryParse(Console.ReadLine(), out int guess);
if (success)
{
while (guess <= 0 || guess > 10)
{
if (success)
{
Console.WriteLine("Bro, just: ");
success = int.TryParse(Console.ReadLine(), out guess);
}
else
{
Console.WriteLine("You are done Brotha");
}
}
printNumber();
Console.WriteLine("--------------");
printNumber();
Console.WriteLine("--------------");
printNumber();
}
else
{
Console.WriteLine("You are done Brotha");
}
Console.ReadKey();
void printNumber()
{
int number = 1;
int num01 = 0;
int attempts = 0;
Random numGen = new Random();
while (num01 != guess && attempts <= 9)
{
Console.ReadKey();
num01 = numGen.Next(1, 11);
Console.WriteLine(number + ". You got: " + num01);
attempts++;
number++;
}
if (num01 == guess && attempts <= 9 && attempts > 1)
{
Console.WriteLine("You WIN!");
Console.WriteLine("And it took you " + attempts + " attempts to roll " + guess);
}
else if (num01 == guess && attempts == 1)
{
Console.WriteLine("You WIN!");
Console.WriteLine("Holy shit!");
}
else if (num01 == guess && attempts == 10)
{
Console.WriteLine("You WIN!");
Console.WriteLine("And it took you " + attempts + " attempts to roll " + guess);
Console.WriteLine("Lucky one Buddy");
}
else
{
Console.WriteLine("You LOSE!");
}
}```the program before was like if the first input is false then it shows "You are done Brotha" and quits the program
but if the first input would be true and then the next ones will be false it would keep asking "Bro just: "
and I wanted to make it that everytime it's false it quits the program
and now it just crashes the program
sick haven
and now it just crashes the program
btw I love it
I didin't mean it but it turned out being even better
void steppe
Okay so remember in the other post how Zenvin said that every program's entry point is the Main method? And that if you don't write one, like you haven't, it gets generated for you implicitly?
sick haven
but I still want to know how to do it how I wanted normally
sick haven
Okay so remember in the other post how Zenvin said that every program's entry po...
yee
void steppe
So a program closes/terminates, whenever the Main method has finished everything
So you need to just return; out of the Main method, in order to quit
It is confusing because it might appear like you're not in a method, so calling return; seems weird and out of context, but that is how it works
sick haven
where do I call it
void steppe
Whenever you want it to quit
Also I misspoke, you don't "call" return, I just said it that way for simplicity sake
It's actually a return statement. But eh whatever
void steppe
It does in this case
return ends the current method
So it will go back to whatever method called it
But since your code is running in the Main method, ending that method consequently ends the program
sick haven
uu
void steppe
You just don't see the Main method because it's generated for you. But it's there
sick haven
nice
I will also want to add some other texts besides only "Bro just: "
so it won't be that plane
void steppe
i.e. a complete program like so:
Console.WriteLine("Hello World");
return;
Console.WriteLine("This message will not print!");
is actually equivalent to something like:
class Program
{
static void Main()
{
Console.WriteLine("Hello World");
return;
Console.WriteLine("This message will not print!");
}
}
the Program class and Main method are just generated for you so you don't have to waste time writing it
