C Program to Print the Kth Element in an Array

Write a C program to print the Kth element in an array using a for loop.

#include <stdio.h>

int main()
{
	int Size, i, k;

	printf("Please Enter the Array size = ");
	scanf("%d", &Size);

	int arr[Size];
	
	printf("Enter the Array %d elements : ", Size);
	for (i = 0; i < Size; i++)
	{
		scanf("%d", &arr[i]);
	}

	printf("Enter Kth Position Array Item to Check = ");
	scanf("%d", &k);

	printf("Kth Element (%d) in this Array = %d \n", k, arr[k - 1]);
}

This C program uses a while loop and prints the Kth element in the given array. In this C example, we used an extra if else to check whether the Kth element is within the array size.

#include <stdio.h>

int main()
{
	int Size, i, k;

	printf("Please Enter the Array size = ");
	scanf("%d", &Size);

	int arr[Size];
	
	printf("Enter the Array %d elements : ", Size);
	for (i = 0; i < Size; i++)
	{
		scanf("%d", &arr[i]);
	}

	printf("Enter Kth Position Array Item to Check = ");
	scanf("%d", &k);

	if(k <= Size)
	{
		printf("Kth Element (%d) in this Array = %d \n", k, arr[k - 1]);
	}
	else
	{
		printf("The Kth Element is Out of this Array Range\n");
	}
}

Please Enter the Array size = 7
Enter the Array 7 elements : 22 9 11 44 99 12 87
Enter Kth Position Array Item to Check = 5
Kth Element (5) in this Array = 99 


Please Enter the Array size = 3
Enter the Array 3 elements : 10 20 30
Enter Kth Position Array Item to Check = 5
The Kth Element is Out of this Array Range
