dvc c++粒子跳动爱心代码

DVC（Digital Video Corporation）是一家专注于视频处理和图像处理的公司，C++粒子跳动爱心代码是一种用C++语言编写的特效代码，可以在屏幕上显示出跳动的爱心效果。以下是一个简单的示例代码：

#include <iostream>
#include <cmath>
#include <cstdlib>
#include <ctime>
#include <windows.h>

const int SCREEN_WIDTH = 80;
const int SCREEN_HEIGHT = 25;

struct Particle {
    double x;
    double y;
    double speed;
    double direction;
};

void initialize(Particle particles[], int numParticles) {
    for (int i = 0; i < numParticles; ++i) {
        particles[i].x = SCREEN_WIDTH / 2;
        particles[i].y = SCREEN_HEIGHT / 2;
        particles[i].speed = static_cast<double>(rand()) / RAND_MAX * 0.4 + 0.2;
        particles[i].direction = static_cast<double>(rand()) / RAND_MAX * 2 * M_PI;
    }
}

void update(Particle particles[], int numParticles) {
    for (int i = 0; i < numParticles; ++i) {
        particles[i].x += particles[i].speed * cos(particles[i].direction);
        particles[i].y += particles[i].speed * sin(particles[i].direction);
        
        if (particles[i].x < 0 || particles[i].x >= SCREEN_WIDTH || particles[i].y < 0 || particles[i].y >= SCREEN_HEIGHT) {
            particles[i].x = SCREEN_WIDTH / 2;
            particles[i].y = SCREEN_HEIGHT / 2;
            particles[i].speed = static_cast<double>(rand()) / RAND_MAX * 0.4 + 0.2;
            particles[i].direction = static_cast<double>(rand()) / RAND_MAX * 2 * M_PI;
        }
    }
}

void draw(Particle particles[], int numParticles) {
    char screen[SCREEN_HEIGHT][SCREEN_WIDTH];
    for (int i = 0; i < SCREEN_HEIGHT; ++i) {
        for (int j = 0; j < SCREEN_WIDTH; ++j) {
            screen[i][j] = ' ';
        }
    }
    
    for (int i = 0; i < numParticles; ++i) {
        int x = static_cast<int>(particles[i].x);
        int y = static_cast<int>(particles[i].y);
        screen[y][x] = '*';
    }
    
    for (int i = 0; i < SCREEN_HEIGHT; ++i) {
        for (int j = 0; j < SCREEN_WIDTH; ++j) {
            std::cout << screen[i][j];
        }
        std::cout << std::endl;
    }
}

int main() {
    const int NUM_PARTICLES = 100;
    Particle particles[NUM_PARTICLES];
    
    initialize(particles, NUM_PARTICLES);
    
    while (true) {
        update(particles, NUM_PARTICLES);
        draw(particles, NUM_PARTICLES);
        Sleep(100); // 控制帧率
        system("cls"); // 清屏
    }
    
    return 0;
}

这段代码使用了Windows API中的`Sleep`函数来控制帧率，以及`system("cls")`函数来清屏。它通过不断更新粒子的位置，并在屏幕上绘制出来，实现了粒子跳动爱心的效果。
