Cpp program to merge two sorted arrays

Write a cpp program to merge two sorted arrays (ascending order)

Solution

#include<iostream>
using namespace std;
int main(){
    int arr[5],AR[3],rslt[10],i;
    cout<<"Enter the 5 elements of first array";
    for(i=0;i<5;i++)
    {
        cin>>arr[i];
    }
    cout<<"Enter the 3 elements of second array";
    for(i=0;i<3;i++)
    {
        cin>>AR[i];
    }
    int p1=0,p2=0,a=0;
    while(p1<5 && p2<3)
    {
        if(arr[p1]<=AR[p2])
        {
            rslt[a]=arr[p1];
            p1++;
        }
        else
        {
            rslt[a]=AR[p2];
            p2++;   
        }
        a++;
    }
    while(p1<5)
    {
        rslt[a]=arr[p1];
        p1++;
        a++;
    }
    while(p2<3)
    {
        rslt[a]=arr[p1];
        p1++;
        a++;
    }
    cout<<" SORTED ARRAY :"<<endl;
    for(i=0;i<8;i++)
    {
        cout<<rslt[i]<<" ";
    }
    return 0;
}

Output

Enter the 5 elements of first array

12

24

36

48

60

Enter the 3 elements of second array

5

10

15

SORTED ARRAY :

5 10 12 15 24 36 48 60
