This is how I would do it only there would be more operations and a try catch exception handler

// geo121's simple calculator!
#include <iostream.h>

int main()
{
     cout << "\n\n\n\n\n\nWelcome to Geo121's Calculator\n\nThis Calculator is used to calculate various math operations\n\nWhen Prompted enter a value for the first number\n\nThen the symbol for the operation\n\nThen another number for the second value\n\nThe symbols for the operations are as followed : \n\n+ is used for addition\n\n- is used for subtraction\n\n* is used for multiplication\n\n/ is used for division\n\n\nMORE OPERATIONS TO COME\n\n";
     float num2;
     float num1;
     char op;
     // this documentation it isn't required
     // char op in ASCII
     // + = 43
     // - = 45
     // * = 42
     // / = 47

     float ans;
     cout << "Please Enter the First Number: ";
     cin >> num1;
     cout << "Please Enter the Operation Symbol: ";
     cin >> op;
     cout << "Please Enter the Second Number: ";
     cin >> num2;
     switch (op)
     {
          case 43: // operation symbol was + in ASCII is 43
               ans=num1+num2;
               break;
          case 45: // operation symbol was - in ASCII is 45
               ans=num1-num2;
               break;
          case 42: // operation symbol was * in ASCII is 42
               ans=num1*num2;
               break;
          case 47: // operation symbol was / in ASCII is 47
               ans=num1/num2;
               break;
          default: // operation symbol was invalid
               cout << "\n\n\nIncorrect Operation\n\n\n";
               break;
     }

     cout << num1 << " " << op << " " << num2 << " = " << ans << endl;

     return 0;
}





If you are new to programming in C++ I would suggest reading

learn C++ in 21 days

It actually takes less if you try and it also teaches some key computer programming concepts

such as code organization and memory management
