Love symbol c Love beating code sharing

Use C code to draw the beating love, constantly change the size and position of the heart through loops, and clear the screen with ClearDevice(), so that the love can simulate the beating effect. The EasyX graphics library is used to control changes using sinusoidal functions to simulate jumps, but it is necessary to reduce the number of calls to ClearDevice() and set the delay parameters reasonably. This code can be used as a basis and is further improved by customizing colors, special effects and rotations. At the same time, it emphasizes the enjoyment of code readability, maintainability and programming.

Make your C program feel heart-pounding: Heartbeat code sharing

Have you ever thought of using C code to draw a beating heart? Not just a static pattern, but a dynamic, as if it is really beating? This is not a fantasy, let us unveil the mystery of this romantic code together. After reading this article, you can not only learn to draw beating hearts, but also understand some of the skills of C graphics programming behind it, as well as some pitfalls and solutions I encountered in practice.

First, we need some basic knowledge. This is not a profound rocket science, it only requires you to have some understanding of the basic syntax of C and some graphics libraries. I will use a relatively simple library here - EasyX , because it is easy to get started and is enough to complete our tasks. Of course, you can also choose other graphics libraries, such as SFML or OpenGL. The principles are the same, but the code implementation details will be different.

I won’t go into details about the installation and configuration of EasyX. There are a lot of online tutorials, and I believe you can handle it easily. Next, let's go straight to the core: How to make love beat.

The simplest idea is to constantly draw heart shapes of different sizes or positions to simulate the beating effect. We can use a loop to change the parameters of the heart shape each time, then call ClearDevice() to clear the screen, and then re-draw it.

 <code class="cpp">#include <graphics.h> #include <conio.h> #include <math.h> int main() { initgraph(640, 480); // 初始化图形窗口int x = 320, y = 240; // 心形中心坐标int size = 50; // 心形大小while (!kbhit()) { // 按任意键退出ClearDevice(); // 清除屏幕// 绘制爱心，这里用的是一个简单的算法，你可以尝试更复杂的算法for (double i = 0; i </math.h></conio.h></graphics.h></code>

The core of this code lies in size = sin(GetTickCount() / 100.0) * 2; This line, it uses a sinusoidal function to simulate the periodic changes of the heart shape, thereby achieving a beating effect. GetTickCount() function gets the system time to make the jump more natural.

Of course, this is just a very basic example that you can improve according to your preferences. For example, you can try changing the color, adding some special effects, and even letting the love spin.

Here are some pitfalls I have stepped on. Once upon a time, I kept modifying the size and position of the heart shape directly in the loop, which resulted in very unsmooth beating and even flashing. Later I found that ClearDevice() function is time-consuming and should minimize the number of calls. In addition, it is important to control the parameters of delay() function well. The parameters are too small, the jump is too fast, the parameters are too large, and the jump is too slow, and it needs to be adjusted according to the actual situation.

Finally, remember that the readability and maintainability of the code are very important. Clear comments and standardized code styles can help you make twice the result with half the effort when modifying and maintaining code in the future. Don’t forget that programming is a fun thing. If you try boldly and constantly improve, you can create more amazing works!
