Answer 2

Sample Program in C++:

#include<iostream>

using namespace std;

int main()

{

char result;

float num1,num2;

cout << "Enter an operator\n";

cin >> result;

cout << "Enter two numbers:\n";

cin >> num1 >> num2;

switch(result)

{

case '+':

cout << num1 + num2;

break;

case '-':

cout << num1 - num2;

break;

case '*':

cout << num1 * num2;

break;

case '/':

cout << num1 / num2;

break;

default:

printf("Incorrect");

}

return 0;

}

Note: In some cases, num1 > num2.. You can write it using if else condition.

Output:

Please select an Operator:

+

Enter two numbers:

10 20

30.
