小丑竟然是自己
今天上午刚打完美赛，和其他两个队友一起奋斗了四天，最后一晚通宵，彻夜未眠，虽然很累，但看到写出一篇25页全英latex排版论文还是挺开心的。如果不得奖的话都打算退出建模圈了，比完赛看了一眼桌面右下角时间
还有两天就除夕了，还有五天就情人节了，额额额，我为什么要加一个就字，情人节好像和我还没啥关系。。。
但至少曾今还是有关系的，曾经有过两段感情，包括初恋，都是以我被分手告终，有时候想想是有点难过，可能的确是自己的原因吧，要么是自己性格的缺陷或者自己还不够足够优秀吧
既然情人节快到了，整理了几种画玫瑰线的代码，祝大家早日找到幸福的TA
Python版本动态画玫瑰

c语言画心形
代码
#include <stdio.h>
#include <math.h>
int main()
{
//FILE *fp = fopen("graph.txt", "w+");
float x, y, f;
for(y = 1.6; y >= -1.6; y -= 0.15){
for(x = -1.1; x <= 1.1; x += 0.05){
f = x*x + pow(y - pow(x*x, 1.0/3), 2) - 1; //函数方程
//fputc(f <= 1E-5 ? '*' : ' ', fp);
putchar(f <= 1E-5 ? '*' : ' ');
}
//fputc('\n', fp);
putchar('\n');
}
for(y = 1.6; y >= -1.6; y -= 0.15){
for(x = -1.1; x <= 1.1; x += 0.05){
f = x*x + pow(y - pow(x*x, 1.0/3), 2) - 1; //函数方程
//fputc(f > 1E-5 ? '*' : ' ', fp);
putchar(f > 1E-5 ? '*' : ' ');
}
//fputc('\n', fp);
putchar('\n');
}
//fclose(fp);
return 0;
}
由于c没有图形界面，只有在控制台输出啦
