#include <iostream>

#define COLS 6
  
int row_include_number(int matrix[][COLS], int row, int cols, int number) {
    for (int j = 0; j < cols; j++) {
        if (matrix[row][j] == 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 row = 2;
    int number = 89;
