Code:

include <iostream> using namespace std; int main() { int n; while (cin >> n) //多组输入 { //上半部分（包含中间行） for(int i = 1; i <= n; i++) { //打印前置空格 for(int j = 1; j <= n - i; j++) cout << ' '; //升序 1~i for(int j = 1; j <= i; j++) cout << j; //降序 i-1 ~1 for(int j = i - 1; j >= 1; j--) cout << j; cout << endl; } //下半部分 for(int i = n - 1; i >= 1; i--) { for(int j = 1; j <= n - i; j++) cout << ' '; for(int j = 1; j <= i; j++) cout << j; for(int j = i - 1; j >= 1; j--) cout << j; cout << endl; } } return 0; }
