Multi-Dimensional Arrays - stuck on code

You are a movie theater manager. You are given a two-dimensional array with 6 rows and 6 columns - 36 elements with 0 value, that represent empty theater seats. All 36 tickets for session were sold, so you need to identify all of the seats with value 1. Write a program that replaces all 0 values in the given array by 1 and outputs the resulting matrix. All I got is change 0 to 1 in the first column. How do I do the rest? https://www.sololearn.com/learning/1051/1629/2857/1

for (int rows = 0; rows < 6; rows++) { for (int cols = 0; cols < 6; cols++) { cout << matrix[rows][cols] + 1; also works. Is one better than the other as far as functionality?

import numpy as np data = np.array([1, 1, 0, 0, 1, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 0, 1, 0, 1, 1, 1, 1, 0, 0, 0, 1, 1, 1, 0]) row = int(input()) data = data.reshape(6,5) print(data[row])

#include <iostream> using namespace std; int main() { string arr[3][3] = { {"Python", "JS", "C++"}, {"PHP", "SQL", "Java"}, {"C#", "Swift", "Kotlin"}, }; // your code goes here cout<<arr[0][2]<<endl; return 0; } Good Luck

int i, j; for (i = 0; i < rows; i++){ for (j = 0; j < cols; j++){ matrix[i][j] = 1; cout << matrix[i][j] << endl; } }

agree with the options above. but I would add if function. // your code goes here for (int x=0; x<rows;x++){ for(int y=0; y<cols;y++) { cout << matrix[rows][cols]+1; if(y>4) cout << endl; } }
