Does Anyone Know Why This Code Is Printing The Number Ten??

Question

I'm having an issue with making a calculator in C++. The calculator itself is working, however, after the calculation, the program prints the number ten to the screen and I have no idea why. Can someone help me out?

#include <iostream>
using namespace std;

int calculator(){

int a, b;
char op;

cout << "Enter Operator, Either +, -, *, or /: ";
cin >> op;

cout << "Enter Two Numbers: ";
cin >> a >> b;

switch (op)
{
case '*':
cout << a * b << endl;
cin.get();
break;
case '/':
cout << a / b << endl;
cin.get();
break;
case '+':
cout << a + b << endl;
cin.get();
break;
case '-':
cout << a - b << endl;
cin.get();
break;
}

}

int factorial(int n){

if (n==1){
return 1;
}
else {
return n * factorial (n-1);
}

}

int main() {

cout << calculator();
cout << endl;
cout << factorial(4);

return 0;
}

int calculator() should be void calculator() as it never returns a value.

Answer 2

What is your input to the program?

Answer 3

'Enter operator............. And enter two numbers :24'
Is being printed all the time I run it for any two integers .
