skip/ignore array index that contain value in c -

my goal create c function finds minimum value of array , set zero. far, function ignore/skip indexes zero.

void find_minimum(double a[], int n) {      int i, index;     double low;          index = 0;     low = a[0];      (i = 1; < n; i++) {         if ( a[i] < low && a[i] != 0.0) {             low = a[i];             index = i;         }     }     a[index] = 0.0;       } 

i tried using continue statement this:

void find_minimum(double a[],  int n) {      int i, index;     double low;      index = 0;     low = a[0];      (i = 1; < n; i++) {          if(a[i] == 0.0){           continue;         }         if ( a[i] < low) {             low = a[i];             index = i;         }     }     a[index] = 0.0; } 

what missing or messing up?

your problem is, code ignores case when a[0] zero. try assign low constant double_max , iterate through whole array instead (i = 0 in for initialization statement instead of i = 1).

void find_minimum(double a[], int n) {      int i, index;     double low;          index = 0;     low = double_max;      (i = 0; < n; i++) {         if ( a[i] < low && a[i] != 0.0) {             low = a[i];             index = i;         }     }     a[index] = 0.0;       }
