C program to print all values in an array less than given number

In this article we will learn to implement a C program to print all values in an array less than given number. A C program is provided below to print all the values in an array which are less than the given key element.

The program is as follows:

#include <stdio.h>
#include <conio.h>

int main() 
{
	int n;
	int k;
	printf("Enter n: ");
	scanf("%d", &n);
	int a[20];
	printf("Enter array elements: ");
	for(int i = 0; i < n; i++)
		scanf("%d", &a[i]);
	printf("Enter k: ");
	scanf("%d", &k);
	printf("Array elements less than %d are: \n", k);
	for(int i = 0; i < n; i++)
	{
		if(a[i] < k)
			printf("%d ", a[i]);
	}
	getch();
    return 0;
}

Input and output for the above program is as follows:

Enter n: 6
Enter array elements: 1 3 5 2 4 6
Enter k: 4
Array elements less than 4 are:
1 3 2
