#Can someone help me on how to write code for this problem

what have you tried so far?
wind karma
#include <iostream>
using namespace std;
int main()
{
int num, i, j;
cout << "Enter a number:";
cin >> num ;
for(i = 0; i < num; i++)
{
for(j = 0; j < num; j++)
{
cout << "*";
}
}
return 0;
}```i only have this so far
ive been thinking of how to make it go down but havent got a clue how to
sly trout
```c++
#include <iostream>
using namespace std;
int main()
{
int num, i, j...
;compile
vapid yewBOT
sly trout
🤔 don't remember how to input things anymore
vapid yewBOT
sly trout
anyhow nvm for me trying to get the bot to print stuff
where on your code you getting stuck?
wind karma
one sec
idk how to make it go down and then print out the correct number of asteriks
actually wait i think i know how to make it go down correctly but the number of asteriks still i dont know how to get it correctly
sly trout
well how do you think you could do it?
wind karma
to make it go down i can just put the code outside of the for loop for the asterisks
and for the asterisks i think i can make a formula so it prints out correctly
but that part im stuck
the asterisks part
sly trout
the easiest way imho is to just split it in 2 parts, the ascending and descending part
sly trout
I mean you do have that already:
for(i = 0; i < num; i++)
{
for(j = 0; j < num; j++)
{
cout << "*";
}
}
i get this output
sly trout
well your code is close
a minor modification can get you this:
*
**
***
****
for(j = 0; j < num; j++)
that loop condition isn't very logical
sly trout
yeah
wind karma
but what do I change about it
sly trout
well spoiling it would be spoonfeeding :D
what do you want that loop logically to do?
sly trout
yea
where does it give you a number that has that property
that starts out as 0, then 1 then 2 etc
wind karma
j?
sly trout
no
very important actually
for (i = 1; i <= num; i++)
{
for (j = 0; j < i; j++)
{
cout << "*";
}
std::cout << "\n";
}
take a look at this slightly edited code
wind karma
mhmm
okay so if num is 3
it goes in
first for loop i = 1
second for loop j = 0, i = 1
so it only prints once
then
i = 2
again second for loop j = 0 i = 2 so it prints twice
ohhh
sly trout
yup :)
wind karma
okay thank you
you're a good teacher
okay so for the descending part
imma try
wait
wind karma
for(i = 1; i <= num; i++)
{
for(j = 0; j < i; j++)
{
cout << "*";
}
cout << "\n";
for(z = 0; z < num - i; z++)
{
cout << "*";
}
cout << "\n";
}```i tried this but got a very confusing output
sly trout
ah yeah, that descending loop would need to be further out
for (i = 1; i <= num; i++)
{
for (j = 0; j < i; j++)
{
cout << "*";
}
std::cout << "\n";
}
<-- same code but now descending
yeah after the first loop is done
for (i = 1; i <= num; i++)
{
for (j = 0; j < i; j++)
{
cout << "*";
}
std::cout << "\n";
}
for (i = 1; i <= num; i++) <-- now this loop needs to change
{
for (j = 0; j < i; j++)
{
cout << "*";
}
std::cout << "\n";
}
kinda like this
wind karma
Oh so theres another seperate for loop?
for (i = 1; i <= num; i++)
{
for (j = 0; j < i; j++)
{
cout << "*";
}
std::cout << "\n";
}
for (i = 1; i <= num - i; i++)
{
for (j = 0; j < i; j++)
{
cout << "*";
}
std::cout << "\n";
}
Like that?
Im on mobile cause im on the move
sly trout
yeah this be the easiest way
wind karma
Oh
sly trout
you have some duplicate code now ands stuff but this is the simplest way
that 2nd loop is most likely wrong still
sly trout
for (i = 1; i <= num - i; i++)
most likely want to loop from num - 1 to 0
