How to fill a matrix with 1 and 0 in random locations with C

Answer 1

#include <stdio.h>
#include <stdlib.h> // For rand() and srand()
#include <time.h>   // For time()

#define ROWS 5
#define COLS 4

void fillMatrixWithRandom0and1(int matrix[ROWS][COLS], int rows, int cols) {
    // Seed the random number generator
    srand(time(0));

    // Fill the matrix with random 0s and 1s
    for (int i = 0; i < rows; ++i) {
        for (int j = 0; j < cols; ++j) {
            matrix[i][j] = rand() % 2; // Generates either 0 or 1
        }
    }
}

int main() {
    int matrix[ROWS][COLS];

    fillMatrixWithRandom0and1(matrix, ROWS, COLS);

    // Print the matrix
    for (int i = 0; i < ROWS; ++i) {
        for (int j = 0; j < COLS; ++j) {
            printf("%d ", matrix[i][j]);
        }
        printf("\n");
    }

    return 0;
}
