如果你想編一個簡單的聖誕樹的話這裏也許有你要的東西
這是我當時初學的時候寫的
每片葉子都是我一個一個試出來的
後來也沒有進行縮減有興趣的同學自己試試縮減吧（語句都很簡單我只是懶而已）
代碼可直接複製使用我試了下
#include<stdio.h>
int main(void)
{int i,j,k,z,a,n;
printf("首先祝這個電腦前的小可愛聖誕快樂(～￣▽￣)～");printf("\n");
printf("接下來有幾個選項需要您的選擇你需要我的創造者給您畫的聖誕樹還是自己做一個呢？",n);
printf("\n");
printf("看創造者的選0如果想自己做呢選1祝您開心o(*^＠^*)o");printf("\n");
