C Program to Insert Element at Specific Position in Array

Write C Program to Insert Element at Specific Position in Array

// C Program to Insert Element at Specific Position in Array

#include <stdio.h>

int main()
{
	int A[] = {1, 2, 45, 34, 54, 24, 52, 75};
	int i, x, pos,n;
	n = sizeof(A) / sizeof(A[0]);

    printf("Array Elements :--> ");
	for (i = 0; i < n; i++)
		printf("%d ", A[i]);


	printf("\nEnter Element to Insert :--> ");
	scanf("%d",&x);

	printf("Enter Position to Insert At :--> ");
	scanf("%d",&pos);

	// increase the size by 1

	n++;
	if(pos > n)
	{
		printf("\nInvalid Position");
	}
	else
	{
		// shift elements forward
		for (i = n; i >= pos; i--)
			A[i] = A[i - 1];

		// insert x at pos
		A[pos - 1] = x;

		printf("\nArray After Insertion :--> ");
		for (i = 0; i < n; i++)
			printf("%d ", A[i]);

	}
	return 0;
}

Output:

Run 1:
Array Elements :--> 1 2 45 34 54 24 52 75
Enter Element to Insert :--> 111
Enter Position to Insert At :--> 2

Array After Insertion :--> 1 111 2 45 34 54 24 52 75


Run 2:
Array Elements :--> 1 2 45 34 54 24 52 75
Enter Element to Insert :--> 111
Enter Position to Insert At :--> 12

Invalid Position
