C++ Program to Merge two Arrays

This c++ program merge two arrays in a third array. First you have to enter the size and elements of two arrays, and then both arrays are merged using for loop.

C++ Program to Merge two Arrays

#include<iostream>

using namespace std;

int main()

{

    int arr1[50], arr2[50], arr3[100], n1, n2, i;

    cout<<"Enter Size of Array 1: ";

    cin>>n1;

    cout<<"Enter Elements of Array 1: ";

    for(i=0; i<n1; i++)

        cin>>arr1[i];

    cout<<"\nEnter Size of Array 2: ";

    cin>>n2;

    cout<<"Enter Elements of Array 2: ";

    for(i=0; i<n2; i++)

        cin>>arr2[i];

    for(i=0 ; i<n1; i++)

        arr3[i] = arr1[i];

    for(int j=0, i=n1; i<n1+n2; i++, j++)

        arr3[i]=arr2[j];

    cout<<"\nMerged Array is: ";

    for(i=0; i<n1+n2; i++)

        cout<<arr3[i]<<"  ";

    return 0;

}

OUTPUT:

Enter Size of Array 1: 3

Enter Elements of Array 1: 1 2 3

Enter Size of Array 2: 3

Enter Elements of Array 2: 4 5 6

Merged Array is: 1  2  3  4  5  6
