Question

How to print a specific column of a matrix in C

Answer 1

#include <stdio.h>

#define COLS 4

void print_column(int matrix[][COLS], int rows, int col) {
    for (int i = 0; i < rows; i++) {
        printf("%d ", matrix[i][col]);
    }
}

int main() {
    int matrix[][COLS] = {
        {3, 2, 5, 1},
        {4, 7, 6, 5},
        {9, 3, 0, 1}
    };

    int rows = sizeof(matrix) / sizeof(matrix[0]);

    print_column(matrix, rows, 1);

    return 0;
}
