Course Introduction
Programs for practice
To merge two arrays in C++ programming, you have to ask to the user to enter the array 1 size and elements then array 2 size and elements to merge both the array and store the merged result in the third array say merge[ ]. So to merge two array, start adding the element of first array to the third array (target array) after this start appending the elements of second array to the third array (target array) as shown here in the following program.
Source Code: Merge Two Arrays
/* C++ Program - Merge Two Arrays */
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int arr1[50], arr2[50], size1, size2, size, i, j, k, merge[100];
cout<<"Enter Array 1 Size : ";
cin>>size1;
cout<<"Enter Array 1 Elements : ";
for(i=0; i<size1; i++)
{
cin>>arr1[i];
}
cout<<"Enter Array 2 Size : ";
cin>>size2;
cout<<"Enter Array 2 Elements : ";
for(i=0; i<size2; i++)
{
cin>>arr2[i];
}
for(i=0; i<size1; i++)
{
merge[i]=arr1[i];
}
size=size1+size2;
for(i=0, k=size1; k<size && i<size2; i++, k++)
{
merge[k]=arr2[i];
}
cout<<"Now the new array after merging is :\n";
for(i=0; i<size; i++)
{
cout<<merge[i]<<" ";
}
getch();
}
