Answer / whyname
To merge to arrays ( Note the question has no mention of
sorting the array elements, hence the program below just
merges two arrays)
int array1[5] = {1,2,3,4,5};
int array2[7] = {6,7,8,9,10,11,12};
int i;
int merged[(sizeof(array1)+ sizeof(array2))/sizeof(int)];
memcpy( merged, array1, sizeof(array1));
memcpy( (merged+5), array2, sizeof(array2));
for(i=0;i<(sizeof(merged)/sizeof(int)); i++)
{
printf("%d\n",merged[i]);
}

//#include<stdio.h>

#include<iostream>
using namespace std;
int merge(int A[],int B[],int C[],int m,int n)
{
int i=0, j=0, k=0,len=0;
while (i < m && j < n)
{
if (A[i] <B[j])
{
C[k] = A[i];
i++;
len++;
}
else if(A[i] >B[j])
{
C[k] = B[j];
j++;
len++;
}

{
C[k]=A[i];

if (i < m)
