finding sum,min,max with array

Question

Write a program that inputs number of values then inputs these values (double type) one by one in a loop and finally outputs their sum, the maximum value and the minimum value.

Answer 1

If you dont know the array dimension before, use dynamic allocation.

replace

float nu[];

i=nu[];

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

with:

float *nu=0;
printf("Number of values :");
scanf("%f",&i);
nu=malloc(i*sizeof*nu); if(!nu) fprintf(stderr,"not enough memory"),exit(1);
...
free(nu);
