2522번: 별 찍기 - 12

구현문제다.

#include <iostream>

using namespace std;

int n;

int main() {
	ios_base::sync_with_stdio(false);
	cin.tie(0);
	cout.tie(0);

	cin >> n;

	for (int i = 1; i <= n; i++) {
		for (int j = 0; j < n - i; j++) cout << ' ';
		for (int j = 0; j < i; j++) cout << "*";
		cout << '\n';
	}
	for (int i = n-1; i > 0; i--) {
		for (int j = 0; j < n - i; j++) cout << ' ';
		for (int j = 0; j < i; j++) cout << "*";
		cout << '\n';
	}
}

전체코드다.
