#Help with a simple beginner program. Not understanding where I went wrong...

I keep getting this when trying to format the code :/

Nah it's still doing it. I went into my setting to change things and everything 😦
green latch
how long is your code?
dawn bolt
With comments included 77 lines

Not sure why it's not letting you post it then. Just try to post it without formatting it

//A milk carton can hold 3.78 liters of milk. Each morning, a dairy farm
//ships cartons of milk to a local grocery store. The cost of producing
//one liter of milk is $0.38, and the profit of each carton of milk is
//$0.27. Write a program that does the following:
//a. Prompts the user to enter the total amount of milk produced in the
//morning.
//b. Outputs the number of milk cartons needed to hold milk. (Round
//your answer to the nearest integer.)
//c. Outputs the cost of producing milk.
//d. Outputs the profit for producing milk.
//Include header file to allow input/output
#include <iostream>
//Include directive to avoid unnecessary repetition.
using namespace std;
//Declare a constant to represent the capacity of a carton of milk.
const double carton = 3.78;
//Create main function.
int main();
{
//Declare variables to represent milk, milk cartons, cost
//to produce, profits, cost per milk produced, and profit
//per milk produced.
double milk;
int milk_Carton;
double cost = 0.38;
double profit = 0.27;
double cost_Per, profit_Per;
//Prompts the user to enter the total amount of
//milk produced in the morning.
cout << "Enter, in liters, the total quantity of milk produced: " << endl;
//Assign the user's input to the milk variable.
cin >> milk;
//Assign value to previously declared variable milk_carton.
milk_Carton = milk / carton;
//Outputs the number of milk cartons needed to
//hold milk. (Round your answer to the
//nearest integer.)
cout << "The number of milk cartons needed to hold milk: " << milk_Carton << endl;
//Assign values to previously declared variables cost_Per
//and profit_Per.
cost_Per = milk * cost;
profit_Per = milk_Carton * profit;
I think it's because I don
dont have nitro. This isn't the full code by the way
Let me delete the comments real quick and see if itll allow me to then

int milk_Carton;
double cost = 0.38;
double profit = 0.27;
double cost_Per, profit_Per;

profit_Per = milk_Carton * profit;
cout << "The cost of producing milk: " << cost_Per << endl;
cout << "Profit: " << profit_Per << endl;
return 0;
}
There we go!

What are the errors?
dawn bolt
it's saying my identifiers are undefined
and an expected declaration in line 28
^this is the first error
green latch
You can either copy paste the errors or screenshot them
It would be tedious to describe all 18 errors lol
green latch
Can you see what's wrong with this part of the code?
int main();
{
is the semi colon unnecessary?
green latch
yes
green latch
It's like you're doing forward declaration if you use semicolon after a function
dawn bolt
Gotcha. So no function uses the semi colon at the end?
green latch
If you're forward declaring a function because the function is below the main function you would use it and some other specific cases but other than that, no.
dawn bolt
Oh it ran!
Oh so you forward functions that are within the main function?
This is like my 3rd week into c++
Super intimidating so far
green latch
for example
int add(int a, int b);
int main(){
int a = 5;
int b = 6;
std::cout << add (a, b);
}
int add(int a, int b){
return a + b;
}
Wow, this code is pretty good for your 3rd week
dawn bolt
It took me forever 😅
green latch
It's already being practical
Using the right type of resources as a beginner is pretty helpful, I'll leave you with some below that are recommended

I'm learning from the D.S. Malik C++ Programming textbook right now. This thing is like a phonebook lol
green latch
learncpp is free from the three of them and a lot of people recommend it
dawn bolt
I really appreciate all of your help and advice!
green latch
You welcome!
dawn bolt
Take care!
