Thread: arithmetic problem

here's the instructions:

write a c program that prompts the user for two integers and one of the letter codes a, s, m, or d.
a - addition
s - subtraction
m - multiplication
d - division

and here's the code i've written so far:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

main()
{
      int x1,      /*first integer value*/
          x2;      /*second integer value*/
      char x;      /*a, s, d, or m*/

      printf("\aEnter the first integer: ");
      scanf("%d",&x1);
      printf("\aEnter the second integer: ");
      scanf("%d",&x2);
      printf("\n\a\aYou inputted %d and %d",x1, x2);
      printf("\n\nEnter one letter code:"
             "\n a - addition"
             "\n s - subtraction"
             "\n d - division"
             "\n m - multiplication\n\n");
      getchar(x);
      getchar(x);

            while(scanf("%c",&x)!=EOF)
               switch(x)
               {
                     case 'a':
                     case 'A':
                           (float)(x1+x2);
                           break;
                     case 's':
                     case 'S':
                           (float)(x1-x2);
                           break;
                     case 'd':
                     case 'D':
                           (float)(x1/x2);
                           break;
                     case 'm':
                     case 'M':
                           (float)(x1*x2);
                           break;
               }
      printf("\n\n%d", x);

the problem i'm having is using the switch statement i think.
