- u表示这个类型是unsigned的,如果没有的话就是signed;
- 8表示这个类型的数据一共有8位;
- t表示这个数据类型是由typedef来定义的;
typedef signed char int8_t;
typedef unsigned char uint8_t;
typedef int int16_t;
typedef unsigned int uint16_t;
typedef long int32_t;
typedef unsigned long uint32_t;
typedef long long int64_t;
typedef unsigned long long uint64_t;[/codesyntax]转载于:https://my.oschina.net/surenpi/blog/481809
