Adding two integer array element wise.

Here given an program that adds two integer array element wise.


#include <iostream>

using namespace std;

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


    int a[] = {11,22,33,44,55};
    int b[]={66,77,88};
    print(a,5);
    print(b,3);
    int* c= sum(a,5,b,3);
    print(c,5);
}

int* sum(int* a, int m, int*b, int n)
{
    int* aa, *bb;
    int mm, nn;
    if(m<n) aa = a, bb=b, mm=m, nn=n;
    else aa=b, bb=a, mm=n, nn=m;
    int* c = new int[nn];
    for(int i=0; i< mm; i++)
    c[i]= aa[i] + bb[i];
    for (int i=mm;i<nn; i++)
    c[i]=bb[i];
    return c;

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

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