L-5 MCS 260 Wed 29 Aug 2001

Below are listings for programs we discussed in class.

/* L-5 MCS 260 Wed 29 Aug 2001 : average of floats */

#include <stdio.h>

int main(void)
{
   float x;
   float sum = 0.0;
   int cnt = 0;

   printf("Give sequence of floats, terminate with RETURN+CTRL-D :\n");

   while (scanf("%f", &x) == 1)
   {
      sum = sum + x;
      cnt = cnt + 1;
   }

   printf("The average %f/%d = %f\n", sum, cnt, sum/cnt);
   return 0;
}

The second program does the same, using operators :

/* L-5 MCS 260 Wed 29 Aug 2001 : average of floats, with operators */

#include <stdio.h>

int main(void)
{
   float x;
   float sum = 0.0;
   int cnt = 0;

   printf("Give sequence of floats, terminate with RETURN+CTRL-D :\n");

   while (scanf("%f", &x) == 1)
   {
      sum += x;
      cnt++;
   }

   printf("The average %f/%d = %f\n", sum, cnt, sum/cnt);
   return 0;
}
