# include <iostream> using namespace std; int main() { char op; float num1, num2; cout << "Enter operator either + or - or * or /: "; cin >> op; cout << "Enter two operands: "; cin >> num1 >> num2; switch(op) { case '+': cout << num1+num2; break; case '-': cout << num1-num2; break; case '*': cout << num1*num2; break; case '/': cout << num1/num2; break; default: cout << "Error! operator is not correct"; break; } return 0; }
