Input and Output:-

                                                         The Sum of array is using recursion 15 

Program:

#include <iostream>

using namespace std;

int sumOfArray(int *arr, int n){

    if(n==0)return 0;

    int ans=(sumOfArray(arr, n-1)+arr[n-1]);

    return ans;

}

int main() {

    int arr[]={1,2,3,4,5};

    int n=sizeof(arr)/sizeof(int);

    cout<<"The Sum of array is using recursion "<<sumOfArray(arr, n)<<endl;

}
