Explanation:

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; } return 0; }
