----------------解决方案--------------------------------------------------------
用TC2.0 编译的

----------------解决方案--------------------------------------------------------
你写的这个程序，关CPU什么事？

函数的声明要写在main外面
----------------解决方案--------------------------------------------------------
编译成功了
除了有２个警告
但是无法执行
还有有谁告诉我一下
为什么会有警告出现呀
谢！
----------------解决方案--------------------------------------------------------
那你看一下撒
----------------解决方案--------------------------------------------------------
没有警告啊～～正常的
----------------解决方案--------------------------------------------------------
我用dev-c++编译的，除了把main函数改为int外，都是好的。运行也是对的啊。
LZ可以试一下。
