Line 50: Are you sure that break is supposed to be there?

Also, it's probably a good idea to check (with an if statement) if the operator entered is a 'c' before asking for the different number, and then using continue to jump back to the top of your loop.

Similarly, if your operator is an 'x', then it'd probably be a better idea to check it before asking for a number and then breaking out of the loop rather than using exit(). Exit(), being a C function, isn't safe to use with C++ objects that have something called a destructor (which many if not most do).

Finally, void main() is evil. Please change it to int main(). :(

I have a simple calculator. for c++

#include <iostream>

using namespace std;

#include <stdlib.h>

void main ()

bool	IsOpValid;
int	number1;
int	number2;
int	answer;
char	Op;
	
s:
number1 = 0;
number2 = 0;
answer = 0;

cout << "Please enter a number and press ENTER: ";
cin >> number1;

do	{
p:
cout << "Please enter an operator, 'c' to clear, or 'x' to turn off and press ENTER: ";
cin >> Op;
IsOpValid = false;

cout << "Please enter another number and press ENTER: ";
cin >> number2;

switch (Op)
{
case '+':
answer = number1 + number2;
break;
case '-': 
answer = number1 - number2;
break;
case '*': 
answer = number1 * number2;
break;
case '/': 
answer = number1 / number2;
break;
case 'c':
case 'C':
break;
IsOpValid = true;
cout << "Clearing Calculator." << endl;

case 'x':
case 'X':
IsOpValid = true;

exit (0);

default:

cout << "You have entered an invalid operator." << endl;
cout << "Please enter +, -, *, /, 'c' or 'x' as operator. " << endl;
break;
}

cout << "The result is: " << answer << endl;

} while (!IsOpValid);
	}
	{
return 0;

}

the only problem it has is when i do C or c which is to clear.. it doesnt clear.. it keeps on saying some messages

and one other problem it has is .. never mind i do a c or a x (exit) . it asks me once again then only i can exit out.. or clear (but clear goes on for ever)
