Calculator programs

Does anyone have a sample calculator program i could look at?

I did a calculator program using MFC too just that it only supports the 4 operations and can perform on 2 numbers only.

If you want, I can email to you the program :)

This is a very simple and basic calculator I wrote in C for a homework assignment a while ago.

Maybee this helps.

Code:

---



#include <stdio.h>
#include <conio.h>

void main(void)
        {
        float num1=1.0, num2=1.0;
        char op;

        while(!(num1==0.0 && num2==0.0) )
                {
                printf("\n\nEnter in Number, operator, and number: ");
                scanf("%f %c %f", &num1, &op, &num2);
                switch(op)
                        {
                        case '+':
                                printf(" = %f", num1 + num2);
                                break;
                        case '-':
                                printf(" = %f", num1 - num2);
                                break;
                        case '*':
                                printf(" = %f", num1 * num2);
                                break;
                        case '/':
                                printf(" = %f", num1 / num2);
                                break;
                        default:
                                printf("Unknown operator");
                        }
                }
        }

P.S
Can someone also tell me how to make this tabbed and indented properly.
Thank you

Not very good, but I have a DOS based Calculator. E-mail me if you would like it.

I used a sample from the MSDN:
