怎么用C++输出杨辉三角前十行

怎么用C++输出杨辉三角前十行

#include 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 ; }

#include"stdio.h" const int k=10; void main() { int a[k][k]={0}; int i,j; for(i=0;i<k;i++) { for(j=0;j<i+1;j++) { if(j==0||j==i)a[i][j]=1; else a[i][j]=a[i-1][j-1]+a[i-1][j]; } } for(i=0;i<k;i++) { for(j=0;j<i+1;j++) { if(a[i][j]!=0)printf("%d\t",a[i][j]); } printf("\n"); } }

请参考： #include<iostream> #include<cmath> using namespace std; int resort(int m,int n) { if(m<0||m<n||n<0) return 0; if(n==1) return m; if(m==n) return 1; else return resort(m-1,n)+resort(m-1,n-1); } void main() { int n; cout<<"input the n:"<<endl; cin>>n; for(int i=0;i<=n;i++) { for(int j=0;j<=i;j++) { cout<<resort(i,j)<<" "; } cout<<"n="<<i<<endl; } } 4
