上面的incompatible type又是一常见的warning,这样的问题大多数情况下应该是okay的,因为C会进行隐式转换,但是像上面的case估计就踩到雷区了,可能它的输出就未必是你想要的了因为a,b是char类型占1byte,而foo()的两个pointer都是int *,所以在里面进行调换的时候就会发生覆盖的情况,要想知道结果就自己试试吧。 CASE...
类似警告：warning:comparison between pointer and integer 类型5：显⽰：warning: comparison is always 0 due to limited range of data type 警告原因：有可能你定义了unsigned int uParam;但是你去做了if(uparam<0)的判断，因为unsigned int型的数据总是>=0的，因此这样的⽐较由于数据类型限制了它的范围，...
