。。。。为什么我看不懂咧。。。

不对哦。貌似是个函数调用。。。可是。。。

哇靠，还有goto。。。无语了。

LZ想要什么结果呀？

我是想在哪个地方放大倍数但是不知道怎么能退出来

Alt+F4呵呵。。。

开玩笑了。。。

图形处理。偶不会。。。等待高人~~~

CF还没有头文件。怒。。。

谢谢各位了我搞明白了

-。-这么快呀？？？说说哪不对了喃？

stop:

if(n!=0){
fun(300,200,r1,r2,x1,h,n);

goto stop;}
else exit(0);
}

if的括号搞错了！！所以else就不行了，不好意思我太笨了

呵呵呵呵。。。学得真快。。。

不是笨啦。难得错误嘛。高手也有难得的时候。

前几天我缺老犯。。。T。T
