#include <stdio.h>  

#define COLS 6
   
int column_include_number(int matrix[][COLS], int rows, int col, int number) {
    for (int i = 0; i < rows; i++) {
        if (matrix[i][col] == number) {
            return 1;
        }
    }
    
    return 0;
}
   
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 col = 4;
    int number = 9;
     
    int rows = sizeof(matrix) / sizeof(matrix[0]);
  
    printf("%s\n", column_include_number(matrix, rows, col, number) ? "yes" : "no");

    return 0;
}
 
   
   
/*
