اینم یه سورس دیگه

کد:

Simple Calculator#include <stdio.h>void main()
{
double number1 = 0.0;
   double number2 = 0.0;
   char operation = 0;   printf("\nEnter the calculation\n");
   scanf("%lf %c %lf", &number1, &operation, &number2);   switch(operation)
   {
    case '+':
       printf("= %lf\n", number1+ number2);
       break;      case '-':
       printf("= %lf\n", number1 - number2);
       break;    case '*':
       printf("= %lf\n", number1 * number2);
       break;      case '/':
       if(number2 == 0)
          printf("\n\n\aDivision by Zero #ERROR!\n");
         else
          printf("= %lf\n", number1 / number2);
            break;      case '%':
       if((long)number2 == 0)
          printf("\n\n\aDevision by Zero #ERROR!\n");
         else
          printf("= %ld\n", (long)number1 % (long)number2);
            break;      default:
       printf("\n\n\aIllegal operation!");
   }
}
