跨年烟花源代码cpp

### C++ 源代码实现跨年烟花效果

为了创建一个简单的跨年烟花模拟程序，在控制台环境中可以利用字符图形来表示烟花的效果。下面是一个基础版本的C++源码，该程序通过随机生成不同位置和颜色的星号(*)代表烟花爆炸瞬间的画面。

#include <iostream>
#include <cstdlib>    // For rand() and srand()
#include <ctime>      // For time()

using namespace std;

void drawFireworks(int height, int width){
    char screen[height][width];
    
    // Initialize the screen with spaces.
    for (int row = 0; row < height; ++row) {
        for (int col = 0; col < width; ++col) {
            screen[row][col] = ' ';
        }
    }

    // Randomly place some '*' on the screen to simulate fireworks explosions.
    const int numStars = 20;
    for (int i = 0; i < numStars; ++i) {
        int randomRow = rand() % height;
        int randomCol = rand() % width;
        screen[randomRow][randomCol] = '*';
    }

    // Print out the final result.
    cout << "Happy New Year!" << endl;
    for (int row = 0; row < height; ++row) {
        for (int col = 0; col < width; ++col) {
            cout << screen[row][col];
        }
        cout << endl;
    }
}

int main(){
    srand(static_cast<unsigned>(time(0))); // Seed for randomness.

    int screenHeight = 15;
    int screenWidth = 40;

    while(true){  
        system("cls"); // Clear console window before drawing new frame.
        drawFireworks(screenHeight,screenWidth);
        Sleep(500);     // Pause execution briefly between frames.
    }

    return 0;
}

这段代码定义了一个`drawFireworks()`函数用于绘制烟花图案，并在一个无限循环内调用此方法以显示动画效果[^1]。注意这里的`Sleep()`函数以及`system("cls")`命令可能依赖于特定平台的支持；对于非Windows环境下的编译器来说，这些部分需要相应调整。
