看別人代碼突然發現還有climits（limits.h）這么個頭文件，以后初始化最大值最小值什么的就方便多
- 符號常量 表示
- CHAR_BIT char 的位數
- CHAR_MAX char 的最大值
- CHAR_MIN char 的最小值
- SCHAR_MAX signed char 的最大值
- SCHAR_MIN signed char 的最小值
- UCHAR_MAX unsigned char 的最大值
- SHRT_MAX short 的最大值
- SHRT_MIN short 的最小值
- USHRT_MAX unsigned short 的最大值
- INT_MAX int 的最大值
- INT_MIN int 的最小值
- UNIT_MAX unsigned int 的最大值
- LONG_MAX long 的最大值
- LONG_MIN long 的最小值
- LONG_MAX unsigned long 的最大值
