Input:

Enter the size of the array:
10
Enter the elements of the array:
45 12 75 34 68 1 69 78 2 4
Enter 'k' to find 'kth' element in the array:
4

Output:

4th element in the array is 34

Implementation:

#include <stdio.h> #define MAX 100000 int main(void) { int a[MAX]; int n,i,k; printf("Enter the size of the array:\n"); scanf("%d",&n); printf("Enter the elements of the array:\n"); for(i=0;i<n;i++) { scanf("%d",&a[i]); } /* finding the kth element */ printf("Enter 'k' to find 'kth' element in the array:\n"); scanf("%d",&k); if(k>n) { printf("size of k='%d' is greater than available n='%d' elements\n",k,n); exit(0); } /* To find some 'kth' element in the array, following notations can be used:(assuming 1-based array indexing) a[k] k[a] *(a+k) *(k+a) */ printf("%dth element in the array is %d",k,a[k-1]); // As array is 0-based indexing return 0; }
