Question

Create a C++ language program which feeds randomly generated number using the rand function into a multidimensional array. Create this array such that it has 5 columns and 5 rows of randomly generated values . Then display the contents of the array, and in addition display the sum of each row and the sum of each column in the array.

Answer 1

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main() {
    srand(time(NULL));
    int arr[5][5];
    for (int i = 0; i < 5; ++i) {
        for (int j = 0; j < 5; ++j) {
            arr[i][j] = rand() % 100;
            cout << arr[i][j] << " ";
        }
        cout << endl;
    }
    cout << endl;
    for (int i = 0; i < 5; ++i) {
        int total = 0;
        for (int j = 0; j < 5; ++j) {
            total += arr[i][j];
        }
        cout << "Sum of row " << (i + 1) << " is " << total << endl;
    }
    cout << endl;
    for (int i = 0; i < 5; ++i) {
        int total = 0;
        for (int j = 0; j < 5; ++j) {
            total += arr[j][i];
        }
        cout << "Sum of column " << (i + 1) << " is " << total << endl;
    }
    return 0;
