C++根据用户输入打印对应的金层塔层数

#include <iostream>
#include <Windows.h>

using namespace std;

int main(void) {
    int row;

    cout << "请输入金字塔层数：";
    cin >> row;

    for (int i = 1; i <= row; i++) {
        for (int k = 0; k < row - i; k++) {
            cout << " ";
        }

        for (int j = 0; j < (2 * i) - 1; j++) {
            cout << "*";
        }
        cout << endl;
    }
    system("pause");
    return 0;
}
