C program to find minimum using function

#include <stdio.h>

int find_minimum(int[], int);
 
int main() {
  int c, array[100], size, location, minimum;
 
  printf("Input 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, index = 0;
 
  for (c = 1; c < n; c++)
    if (a[c] < min)
      index = c;

  return index;
}

output:

Enter number of elements in array

3

Enter 3 integers

1

2

3

Minimum element is present at location 1 and its value is 1.
