C Program for MERGING of Two Arrays with out using Third Array

#include<stdio.h>

int main()

{
	int n1, n2, i, j, *p, *q, a[10], b[10];
	printf("Enter the number of elements in array 1 :: ");
	scanf("%d", &n1);

	printf("Enter the elements : ");
	for(i = 0; i < n1; i++)
	{
		scanf("%d", &a[i]);
	}
	printf("Enter the number of elements in array 2 :: ");
	scanf("%d", &n2);
	printf("Enter the elements : ");

	for(i = 0; i < n2; i++)
	{
		scanf("%d", &b[i]);
	}

	//MERGING THE ARRAY

	p=a;
	q=b;
	for(i = 0, j = n1; i < n2; i++, j++)
	{
		*(p+j) = *(q+i);
	}
	printf("The merged array is :: ");
	for(i = 0; i < j; i++)
		printf("%d  ", a[i]);

	printf("\n");
	return 0;

}

OUTPUT:

Enter the number of elements in array 1 :: 5
Enter the elements : 1 2 3 4 5
Enter the number of elements in array 2 :: 5
Enter the elements : 6 7 8 9 10
The merged array is :: 1  2  3  4  5  6  7  8  9  10
