How to print a specific row of a matrix in C

Answer 1

#include <stdio.h>
  
#define COLS 6
  
void print_row(int matrix[][COLS], int row, int cols) {
    for (int j = 0; j < cols; j++) {
        printf("%d ", matrix[row][j]);
    }
}
  
int main() {
    int matrix[][COLS] = { 
            { 4, 7, 9, 18, 29, 0 },
            { 1, 9, 18, 99, 4, 3 },
            { 9, 17, 89, 2, 7, 5 },
            { 19, 49, 6, 1, 9, 8 },
            { 29, 4, 7, 9, 18, 6 } };
  
    int row = 2;

    print_row(matrix, row, COLS);
  
    return 0;
}
  
  
  
/*
run:
  
9 17 89 2 7 5 
  
*/
