While loop won't end

[Programmingaddict]

I've tried 3 different ways to end the loop and none have worked.
It just scrolls.

#include <iostream>
using namespace std;

bool compute(int base, int exponent, int * result)
{
	if (exponent < 0)
	{
		return(false);
	}
	while(exponent != 0)
	{
		*result *= base;
		exponent -= 1;
	}
	return (true);
}

int main(void)
{	
	bool loop = true;

   while (loop == true)
   {
	int base = 0;
	int exponent = 0;
	int result = 1;
	
	cout << "enter base:     ";
	cin >> base;
	cout << "enter exponent: ";
	cin >> exponent;
   	
	
	//if while loop is here it'll save value that was previously input
	
	
	if (compute(base, exponent, &result) == false)
	{
   	cerr << "exponent must be positive\n";
	}
	else if (loop == true)
	{
		cout << "base    : " << base << endl;
		cout << "exponent: " << exponent << endl;
	    cout << "result  : " << result << endl;
	}
	else
	{
	//	break;
	//	loop = false;
	continue;
	}
	}
	return(0);
}

while (loop == true)
(which can, of course, be simplified to
while (loop)



So, to stop the loop ... set loop = false somewhere!

You do nothing anywhere in your loop to end it.

continue doesn't break out of a loop, it just ends the current iteration and immediately begins the next one. Anyway, it should be obvious that that statement will never be executed.

Your commented-out lines would, for the same reasons, never be executed.

And your return(0) statement is after the end of your loop.

To exit your loop, you could:

1) Use break in a place where it would actually be executed
2) Set loop = false in a place where it would actually be executed
3) Add a return statement to your loop, in a place where it would be executed

EDIT: Also, you would do yourself a huge favour if you adopted a consistent, sensible indentation style.

I tried using loop = false, break, and continue under the else statement, I was just showing all three while not actually executing all 3. If I don't put it in a statement it won't loop. Else should mean if anything else is typed end the loop, but instead it just scrolls.

And as I've already said:

Take a careful, considered look at the logic of your if ... else if ... else block, and I'm sure you'll figure out why the final else block will never actually be executed.

   	//add this to break loop
   	if(cin.fail()) {
	   loop = false;

	else if (loop == true)
	{
		cout << "base    : " << base << endl;
		cout << "exponent: " << exponent << endl;
	    cout << "result  : " << result << endl;
	}

   }
	return(0);
}

Thank you so much
