C++代码 让CPU使用率变成波形

这个只能是单核CPU，多核心CPU做不到这个效果，主要用到了Sin Cos函数，和Sleep函数做出的效果。

上代码！

正弦波曲线

//正弦波曲线
	double time = 0.0;
	double runtime;
	int c;
 
	while (1)
	{
		runtime = 100 + 100 * sin(time);
		time += 0.05;
		c = clock();
 
		while (clock() - c < runtime);
 
		Sleep(200 - runtime);
	}
 
 

横线

//横线
	while (1)
	{
		int start = clock();
		while (clock() - start < 10);
		Sleep(10);
	}

单向斜线

//单向斜线
	int k = -1;
	int c = 0;
	int runtime;
	while (1)
	{
		runtime = 100 + k * (c++ % 101);
 
		int start = clock();
		while (clock() - start < runtime);
		Sleep(100 - runtime);
	}
 

双向斜线

 
//双向斜线
	int k = 1;
	int c = 0;
	int runtime;
	while (1)
	{
		runtime = (int)(c < 100) * (100 + -1 * (c % 100)) + (int)(c > 100) * (c - 100);
		c = c++ % 200;
		int start = clock();
		while (clock() - start < runtime);
 
		Sleep(100 - runtime);
	}
