用这个例子,复习一下C++吧,这是一款学习机器人编程必不可缺的重要语言!

效果是这样的,如下:
字符串版动态甜甜圈
使用编译环境为Win10+Microsoft Visual Studio Community 2019,如下:
编译环境
源代码如下:
#include <stdio.h>
#include <math.h>
#include <cstring>
#include <Windows.h>
void usleep(__int64 usec)
{
HANDLE timer;
LARGE_INTEGER ft;
ft.QuadPart = -(10 * usec);
timer = CreateWaitableTimer(NULL, TRUE, NULL);
SetWaitableTimer(timer, &ft, 0, NULL, NULL, 0);
WaitForSingleObject(timer, INFINITE);
CloseHandle(timer);
}
int main() {
float A = 0, B = 0;
float i, j;
int k;
float z[1760];
char b[1760];
printf("\x1b[2J");
for (;;) {
memset(b, 32, 1760);
memset(z, 0, 7040);
for (j = 0; j < 6.28; j += 0.07) {
for (i = 0; i < 6.28; i += 0.02) {
float c = sin(i);
float d = cos(j);
float e = sin(A);
float f = sin(j);
float g = cos(A);
float h = d + 2;
float D = 1 / (c * h * e + f * g + 5);
float l = cos(i);
float m = cos(B);
float n = sin(B);
float t = c * h * g - f * e;
int x = 40 + 30 * D * (l * h * m - t * n);
int y = 12 + 15 * D * (l * h * n + t * m);
int o = x + 80 * y;
int N = 8 * ((f * e - c * d * g) * m - c * d * e - f * g - l * d * n);
if (22 > y && y > 0 && x > 0 && 80 > x && D > z[o]) {
z[o] = D;
b[o] = ".,-~:;=!*#$@"[N > 0 ? N : 0];
}
}
}
printf("\x1b[H");
for (k = 0; k < 1761; k++) {
putchar(k % 80 ? b[k] : 10);
A += 0.00004;
B += 0.00002;
}
usleep(30000);
}

}
试一下吧,感受编程语言和数学结合的魅力!!!
