#include <iostream> using namespace std ; const int max_line = 10 ; void print_matrix (int matrix[][max_line], int dim) { int i, j; for (i = 0 ; i != dim; i ) { for (j = 0; j != i 1; j ) cout << matrix[i][j] << " " ; cout << endl ; } } void fill_triangle (int matrix[][max_line], int dim) { int i, j ; //第1位跟最后1位赋1 for (i = 0; i != dim; i ) matrix[i][i] = matrix[i][0] = 1 ; //从第2行到最后1行，第1列到i-1列 for (i = 2; i != dim; i ) for (j = 1; j != i; j ) matrix[i][j] = matrix[i-1][j-1] matrix[i-1][j] ; } int main () { int matrix[max_line][max_line] ; fill_triangle (matrix, max_line) ; print_matrix (matrix, max_line) ; return 0 ; }
