ArraySum problem from c++ programming

Question

Write an arraySum using recursion. This should gives out total sum of numbers within the array with the help of recursion!!!!!!!!!!!!!!!

THIS PROGRAMMING SHOULD BE IN C++ PROGRAMMING THAT BEGINS WITH #include<iostream> and then using namespace std; !!!!!!!!!!!!

Answer 1

using namespace std;

#include <iostream>

#define MAX (255)

int input( double * A)

{

int iReturn=0;

cout << "How many ??? :>";

cin >> iReturn;

if (iReturn>MAX) { iReturn=MAX; }

for (int iLoop=0; iLoop<iReturn; iLoop++)

{

cout <<" Please input the number " << (iLoop+1) << " :>";

cin >> A[iLoop];

}

return(iReturn);

}

void arraySum( double * A, int N, double * sum)

{

double sumReturn;

if (N>0)

{ *sum += A[N-1];

arraySum(A,N-1,sum);

}

}

int main()

{

double A[MAX];

int N;

N = input(A);

double sum=0;

arraySum(A,N, &sum);

for (int iLoop=0; iLoop<N; iLoop++) { cout << A[iLoop] << endl; }

cout <<endl << sum << endl;

}
