C program to find minimum element in array using function

#include <stdio.h>
 
int find_minimum(int[], int); 
 
int main() {
  int c, array[100], size, location, minimum;
 
  printf("Enter the number of elements in array\n");
  scanf("%d", &size);
 
  printf("Input %d integers\n", size);
 
  for (c = 0; c < size; c++)
    scanf("%d", &array[c]);
 
  location = find_minimum(array, size);
  minimum  = array[location];
 
  printf("Minimum element location = %d and value = %d.\n", location + 1, minimum);
  return 0;
}
 
int find_minimum(int a[], int n) {
  int c, min, index;
 
  min = a[0];
  index = 0;
 
  for (c = 1; c < n; c++) {
    if (a[c] < min) {
       index = c;
       min = a[c];
    }
  }
 
  return index;
}
