In the following program, show how to append or add one array to another.



#include <iostream>

using namespace std;

int* append(int*, int, int*, int);
void print(int*, int);
int main()
{


    int a[] = {11,22,33,44,55};
    int b[]={66,77,88,99};
    print(a,5);
    print(b,5);
    int* c= append(a,5,b,5);
    print(c,9);
}

int* append(int* a, int m, int*b, int n)
{
    int* c= new int[m+n];
    for (int i=0; i<m;i++)
    c[i]=a[i];
    for(int i=m;i<m+n;i++)
    c[i]=b[i-m];
    return c;

}
void print(int* a, int n)
{

    cout <<"{" << a[0];
    for (int i=1;i<n;i++)
    cout << "," << a[i];
    cout << "} \n";
}
