在C语言中，5种基本数据类型的存储空间长度的排列顺序为：____A_ A、char<int<long int <=float<double B、char=int<long int <=float<double C、char<int<long int=float=double D、char=int=<long int <=float<double
char = signed char = unsigned char < short int = unsigned short int <= int = unsigned int <= long int = unsigned long int <= long long int = unsigned long long int float <= double <= long double 这应该是标准所规定的。

对. 类型名 变量字节 取值范围 [singned]char 1 -128~127 ungsigned char 1 0~255 [singned] long int 4 -2147483648~2147483647 unsiged long [int] 4 0~4294967295 float 4 -3.4E38~3.4E38 7个有效位 double 8 -1.7E308~1.7E308 15个有效位
