#include<stdio.h>
#include<conio.h>
#define size 
main()
{
    int arr1[size],arr2[size],arr3[size+size],i,j,temp=0,no,num,k=0;
    printf("Enter number of element in array first:\t");
    scanf("%d",&no);
    printf("\nEnter element of array first:\n");

        scanf("%d",&arr1[i]);
    }
    printf("\nEnter number of element in array second:\t");
    scanf("%d",&num);
    printf("\nEnter element of array second:\n");
    for(i=0;i<num;i++)
    {
        scanf("%d",&arr2[i]);
    }
