Example: Check Specific Row for All 1s in C

#include <stdio.h>
#include <stdbool.h> // For boolean data type

#define ROWS 3
#define COLS 3

// Function to check if a specific row has all 1s

        if (matrix[row_index][j] == 0) {
            return false; // Found a 0, so not all 1s
        }
    }
    return true; // All elements were 1s
}

int main() {
    // Step 1: Define a sample boolean matrix
    int booleanMatrix[ROWS][COLS] = {
        {1, 1, 1},
        {0, 1, 0},
        {1, 0, 1}

            printf("%d ", booleanMatrix[i][j]);
        }
