小丑竟然是自己
今天上午剛打完美賽，和其他兩個隊友一起奮斗了四天，最后一晚通宵，徹夜未眠，雖然很累，但看到寫出一篇25頁全英latex排版論文還是挺開心的，如果不得獎的話都打算退出建模圈了，比完賽看了一眼桌面右下角時間
還有兩天就除夕了，還有五天就情人節了，額額額，我為什么要加一個就字，情人節好像和我還沒啥關系，，，
但至少曾今還是有關系的，曾經有過兩段感情，包括初戀，都是以我被分手告終，有時候想想是有點難過，可能的確是自己的原因吧，要么是自己性格的缺陷或者自己還不夠足夠優秀吧
既然情人節快到了，整理了幾種畫玫瑰線的代碼，祝大家早日找到幸福的TA

c語言畫心形
代碼
#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; //函式方程
//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; //函式方程
//fputc(f > 1E-5 ? '*' : ' ', fp);
putchar(f > 1E-5 ? '*' : ' ');
}
//fputc('\n', fp);
putchar('\n');
}
//fclose(fp);
return 0;
}
由于c沒有圖形界面，只有在控制臺輸出啦
