Question

C++.Write the body of a function that returns the sum of all elements in a two-dimensional array passed to it as an argument. Declare and initialize all needed variables.

int arraySum(const int numbers[][COLS], int rows)

{

}

Answer 1

This question is little bit confusion based on the requirements provided. So please check below C++ program and revert back in case anything more needs to be implemented.

***** Program *****

#include <iostream>
using namespace std;
const int COLS = 2;
const int numbers[5][2] = { {0,0}, {1,2}, {2,4}, {3,6},{4,8}};

int arraySum(const int numbers[][COLS], int rows) {
int sum = 0;
for ( int i = 0; i < rows; i++ ) {
for ( int j = 0; j < COLS; j++ ) {
sum = sum + numbers[i][j];
}
}
cout << sum << endl;
}

int main()
{
arraySum(numbers,5);
return 0;
}

****** Output ******
