Question

Write a function in C that takes one argument, an array of 50 elements. Your function should print out the index and value of the smallest element in the array.

Answer 1

Code:

#include<stdio.h>
int minimum(int[], int);
int main(){
   int i, n, arr[20], min, pos;
   printf("Enter no. of elements in the array: ");
   scanf("%d",&n);
   printf("Enter %d elements: ",n);
   for(i=1;i<=n;i++){
       scanf("%d",&arr[i]);
   }
   pos = minimum(arr , n);
   min = arr[pos];
   printf("Minimum is %d\n",min);
   printf("Position of minimum is %d",pos);

}

int minimum(int arr[], int n){
   int i, min, pos;
   min = arr[0];
   pos = 0;
   for(i=1;i<=n;i++){
       if(arr[i] < min){
           pos = i;
           min = arr[i];
       }
   }
   return pos;
}
