在初始指针阶段,相信大家对指针已经有了初步了了解,接下来,我们进入C语言的指针进阶部分。在这之前,我们知道: 1.指针是一个变量,是用来存放地址的变量,这个地址唯一标识一块内存空间。 2.指针的大小是固定的4/8个字节,(32位平台/64位平台)。 3.指针也是分为很多类型的,指针的类型决定了指针+-整数的步长,也...
Error codes are typically negative values so when you compare a char against the value from such a macro, the result is always false. A negative number can never be equal to any value of an unsigned type. It is strongly recommended that you never use -xchar to compile routines for any ...
