it's all good

what is the best way to create exit a program? For example:
This program uses a while loop and then checks the inputed value before it enters it again. Is there a shorter better way to do this? Should I use a character or a number? This comes up a lot in my programs and I want to use the fastest, best method.

//grades
#include <iostream.h>

int main()
{
	int count = 0;
	int total = 0;
	int average;
	int grades = 0;
	cout << "Please enter a grade(enter -1 to quit): \n";
	cin >> grades;
	while(grades != -1)
	{total += grades;
	count++;
	cout << "Please enter a grade(enter -1 to quit): \n";
	cin >> grades;}
	average = total / count;
	cout << "Class average is: " << average << endl;
	return 0;
}

Huh?

You've done it, that i can see but you only wnt to make you source code shorter use the 'exit()'function:

as:
if(grade == -1){
exit(o);
}

the prototype is:

#include <stdlib.h>
void exit(int status)

If you want shorter code then you could use a do..while loop, but it won't make much difference. It would save a bit of typing but make your initialisation a bit obscure -

#include <iostream.h>

int main()
{
	int count = -1;
	int total = 1;
	int average;
	int grades = 0;
	do
	{
	cout << "Please enter a grade(enter -1 to quit): \n";
	cin >> grades;
	total += grades;
	count++;
	}while(grades != -1);

	average = total / count;
	cout << "Class average is: " << average << endl;
	
	return 0;
}

When I replied, it was a weird post. It IS modified, you see?
