Need help with loops

[Madshammy]

Cant get my program to loop correctly and i just cant figure it out.

  #include <iostream>
using namespace std;






void avgTwoNumbers(double M, double F);  

void checkNumbers(double someNum);  

void setNumbers(); 


double num1, num2;

char check = 'Y';
char repeat = 'Y';

	
int main() 
{
	char repeat = 'y';

   while( repeat == 'y' || repeat == 'y' )    
   



setNumbers();
avgTwoNumbers(num1, num2);


system("PAUSE");
return 0;
   }


void avgTwoNumbers(double M, double F)
	{
		double total = (M + F)/2;
		cout << "your average grade is " << total << endl;
	}


void checkNumbers(double someNum)
{
	if (someNum < 0 || someNum > 100)
	{
		cout << " Number must be between 0 and 100"  << endl;
		
	}
	else
		check = 'N';

}

void setNumbers()
{
		
	
while (check == 'Y')
{
	cout << "Enter the Midterm grade: ";
	cin >> num1;
	checkNumbers(num1);
	
}

check = 'Y';

while (check == 'Y')
{
	cout << "Enter the Final grade: ";
	cin >> num2;
	checkNumbers(num2);	
}



cout << "Repeat? Y/N" << endl;
      cin >> repeat;   
}

what can't you figure out?

char repeat = 'y';

   while( repeat == 'y' || repeat == 'y' ) 

your loop will always be true but even if it wasn't your code will never run.

- Use do-while loops
- Have the functions return values.
- Make sure your indentation matches the structure of the code. For example, your code executes only one statement (line 31) inside the loop at line 26.

#include <iostream>

using namespace std;

void avgTwoNumbers(double M, double F);
bool checkNumbers(double someNum);
void setNumbers();

double num1, num2;

int
main()
{
    char repeat;
    do {
        setNumbers();
        avgTwoNumbers(num1, num2);
        cout << "Repeat? Y/N" << endl;
        cin >> repeat;
    } while (repeat == 'Y');
    return 0;
}


void
avgTwoNumbers(double M, double F)
{
    double total = (M + F) / 2;
    cout << "your average grade is " << total << endl;
}


bool
checkNumbers(double someNum)
{
    if (someNum < 0 || someNum > 100) {
        cout << " Number must be between 0 and 100" << endl;
        return false;
    } else {
        return true;
    }
}

void
setNumbers()
{
    do {
        cout << "Enter the Midterm grade: ";
        cin >> num1;
    } while (!checkNumbers(num1));

    do {
        cout << "Enter the Final grade: ";
        cin >> num2;
    } while (!checkNumbers(num2));
}
