"This program takes the operator and two operands from the user. Also, the operator is stored in the variable op and two operands which are stored in num1 and num2 respectively.

# include <iostream>

using namespace std;

int main() {

  char op;

  float num1, num2;

  cout << ""Enter operator: +, -, *, /: "";

  cin >> op;

  cout << ""Enter two operands: "";

  cin >> num1 >> num2;

  switch(op) {

    case '+':

      cout << num1 << "" + "" << num2 << "" = "" << num1 + num2;

      break;

    case '-':

      cout << num1 << "" - "" << num2 << "" = "" << num1 - num2;

      break;

    case '*':

      cout << num1 << "" * "" << num2 << "" = "" << num1 * num2;

      break;

    case '/':

      cout << num1 << "" / "" << num2 << "" = "" << num1 / num2;

      break;

    default:

      // If the operator is other than +, -, * or /, error message is shown

      cout << ""Error! operator is not correct"";

      break;
