C++代码实现矩形绘制 - 空心/实心可选

#include <iostream>
using namespace std;

int main() {
    int height, width, solid;
    char symbol;
    cin >> height >> width >> symbol >> solid;

    if (solid == 1) {
        for (int i = 0; i < height; i++) {
            for (int j = 0; j < width; j++) {
                cout << symbol;
            }
            cout << endl;
        }
    } else {
        for (int i = 0; i < height; i++) {
            for (int j = 0; j < width; j++) {
                if (i == 0 || i == height - 1 || j == 0 || j == width - 1) {
                    cout << symbol;
                } else {
                    cout << ' ';
                }
            }
            cout << endl;
