signed char is 8 bit
unsigned short is 16 bit
signed short is 16 bit
unsigned int is 32 bit
signed int is 32 bit
float fp32 is 32 bit
double fp64 is 64 bit
unsigned long is 32 bit
复制代码（上述结果是在arm-gcc编译得出）
在32位系统中
Long int = int = 32bit short int = 16bit
在16位系统中
short int = int = 16bit long int = 32bit
总之: short int = 16bit long int = 32bit
