Question

i wrote the code but i dont get max value how to find max value

#include <stdio.h>
int main(void)
{
        double temp[0];
        float max,min;
        float i;
        short c,j,k;
        float sum=0;
        float nu[c];

        printf("Number of values :");
        scanf("%f",&i);

        for (c=1;i>=c;c++)
        {
          printf("values=");
          scanf("%f",&nu[c]);

          nu[c]=temp[0];

          for (j = 0; i>=j; j++)
          {
             if (temp[0]> nu[c])
             {
             //      nu[c]=temp[0];
                  max = temp[0];

             }
        }
        sum = sum + nu[c];
      }
      printf("sum = %f \n",sum);
      printf("maximum value = %f\n",max);
}

If you run your compiler with a -Wall (as you should always do), you should have seen the problems :

gcc -Wall -o foo foo.c
foo.c: In function 'main':
foo.c:35:14: warning: unused variable 'k'
foo.c:33:14: warning: unused variable 'min'
foo.c:62:1: warning: control reaches end of non-void function
foo.c:37:4: warning: 'c' is used uninitialized in this function

Here is the source code of a program that works :

#include <stdio.h>

int main(void)
{
   float max = 0; // hypothesis : numbers keyed by the users are > 0
   float min = 0; // hypothesis : numbers keyed by the users are > 0
   int i, c;
   float sum = 0;
   float nu[100]; // hypothesis : no more than 100 numbers keyed by user
                  // hypothesis : float type is enough to store numbers keyed by user
   printf("Number of values :");
   scanf("%d",&i);

   for (c = 0; c < i; c++)
   {
         printf("values=");
         scanf("%f",&(nu[c]));

         if (nu[c] > max) {
            max = nu[c];
         }

         if (min == 0) {
            min = nu[c];
         } else if(nu[c] < min) {
            min = nu[c];
         }

         sum = sum + nu[c];
   }
   printf("sum = %f \n",sum);
   printf("maximum value = %f \n", max);
   printf("minimum value = %f \n", min);

   return 0;
}
