以前写过一个Window下的数字雨，像黑客帝国里那样的01数字，现在补充一版Linux下的。使用了curses库，安装方法与使用方法参照

效果如下：
代码如下：
#include <time.h>
#include <curses.h>
#include <stdio.h>
#include <chrono>
#include <thread>typedef struct //记录雨滴的结构体
{int x;int y;char ch;
}RAINDROP;const int BUFFER_SIZE = 50; //雨线数量
int WIDTH = 80;
int HEIGHT = 30;
const int RAIN_LENGTH = 18; //雨线长度RAINDROP raindropLine[BUFFER_SIZE];
WINDOW *HOUT = initscr();//获得标准输出的句柄int main()
{if (has_colors() == TRUE){start_color(); //初始化颜色显示init_pair(1, COLOR_RED, COLOR_WHITE); //只能是颜色库里面8中颜色的组合init_pair(2, COLOR_BLUE, COLOR_GREEN);init_pair(3, COLOR_BLACK, COLOR_GREEN);init_pair(4, COLOR_GREEN, COLOR_BLACK);}HEIGHT = LINES; //根据控制台的宽高设置显示的宽高WIDTH = COLS;noecho();srand((unsigned int)time(NULL));for (int i=0; i<BUFFER_SIZE; i++) //随机设置雨滴下落的位置{raindropLine[i].x = rand()%WIDTH;raindropLine[i].y = rand()%HEIGHT;raindropLine[i].ch = rand() %2 + 48; //设置雨滴内容0或1}while(true){curs_set(0);//GetConsoleScreenBufferInfo(HOUT, &info); //当窗体大小变化时，重新设置宽高信息HEIGHT = LINES;WIDTH = COLS;for (int i=0; i<BUFFER_SIZE; ++i){if (raindropLine[i].y <= HEIGHT){mvaddch(raindropLine[i].y, raindropLine[i].x, raindropLine[i].ch | COLOR_PAIR(4)); //设置雨滴颜色}mvaddch(raindropLine[i].y - RAIN_LENGTH, raindropLine[i].x, ' ');raindropLine[i].y++;raindropLine[i].ch = rand() % 2 + 48;if (raindropLine[i].y > HEIGHT + RAIN_LENGTH){raindropLine[i].x = rand() % WIDTH;raindropLine[i].y = rand() % HEIGHT;}if ( raindropLine[i].y <= HEIGHT){mvaddch( raindropLine[i].y, raindropLine[i].x, raindropLine[i].ch | COLOR_PAIR(4) | A_BOLD); //高亮最下方的雨滴}}refresh();std::this_thread::sleep_for(std::chrono::milliseconds(100));}getchar();return 0;
}
编译命令
gcc main.cpp -o rain -lpthread -lcurses
