Making a calculation based on the operator a user inputs

[Austink95]

Hello,
not sure how to go about solving this.

  cout << "Enter the first number: ";
   cin >> numberOne; 
   cout << "Enter the second number: ";
   cin >> numberTwo; 
   cout << "Enter an operator (+.-.*,/): ";
   cin >> operation;

#include <iostream>
using namespace std;

int main()
{
	int numberOne {}, numberTwo {};
	char operation {};

	cout << "Enter the first number: ";
	cin >> numberOne;

	cout << "Enter the second number: ";
	cin >> numberTwo;

	cout << "Enter an operator (+.-.*,/): ";
	cin >> operation;

	switch (operation) {
		case '+': cout << numberOne + numberTwo; break;
		case '-': cout << numberOne - numberTwo; break;
		case '*': cout << numberOne * numberTwo; break;
		case '/': cout << numberOne / numberTwo; break;
		default: cout << "unknown operand";
	}
	cout << '\n';
}

if the operation is declared as a string would this still work?

switch requires an integral type. Even a char array won't work with a switch since it is not an integral type the compiler understands.

A std::string is not a built-in type in C++, so won't work with a switch.

Without a bit of coding voodoo hackery:
