不同的整数类型之间的区别 [英] Difference between different integer types

问题描述

我想知道是什么 uint32_t的之间的差异， UINT32 ，当我在头看了看文件，这一点过这样的：

I was wondering what is the difference between uint32_t and uint32, and when I looked in the header files it had this:

types.h:

    /** @brief 32-bit unsigned integer. */
    typedef unsigned int uint32;
stdint.h:

    typedef unsigned   uint32_t;

这只会导致更多的问题：
之间有什么

This only leads to more questions: What is the difference between

unsigned varName;

和

unsigned int varName;

我使用的MinGW。

推荐答案

无符号和 unsigned int类型是同义的，就像 [无符号]总之[INT] 和 [无符号]长[INT] 。

unsigned and unsigned int are synonymous, much like [unsigned] short [int] and [unsigned] long [int].

uint32_t的是一类的（可选）由C标准定义。 UINT32 只是一个名字你做了，虽然它发生在被定义为同样的事情。

uint32_t is a type that's (optionally) defined by the C standard. uint32 is just a name you made up, although it happens to be defined as the same thing.
