弹跳小球C语言

#include <iostream>
#include <cstdlib>
#include <Windows.h>
using namespace std;

int main()
{
    int i, j;
    int x = 0;
    int y = 5;
    int velocity_x = 1;
    int velocity_y = 1;
    int left = 0;
    int right = 20;
    int top = 0;
    int bottom = 10;

    while(1){
        
        x = x + velocity_x;
        y = y + velocity_y;
        system("cls");

        for (i = 0; i < x; i++)
            cout << endl;
        for (j = 0; j < y; j++)
            printf(" ");
        printf("o
");

        Sleep(50);
        if (x == top || x == bottom) {
            velocity_x *= -1;
            printf("a");
        }

        if (y == left || y == right) {
            velocity_y *= -1;
            printf("a");
        }
    }
    return 0;
}

最基础的实现，小球撞到墙壁即反弹，触碰会发出声音，仅此而已。

时隔一年，又看到了这份代码，就发出来吧。
