unsigned long:4个字节 32位编译器 char :1个字节 char*(即指针变量):4个字节(32位的寻址空间是2^32, 即32个bit,也就是4个字节。同理64位编译器) short int : 2个字节 int:4个字节 unsigned int :4个字节 float:4个字节 double:8个字节
在VC中不支持这样的表示,是用_int64表示,参考资料:http://www.byvoid.com/blog/c-int64/
这个问答内容是在C或C++语言中的一个语法问题。它是在定义一个别名时使用的typedef关键字,意味着将uint64_t这个数据类型重命名为uint64_t。 在C或C++语言中,typedef用于...
你得定义32字长。但是如果在支持16位长的CPU上,显然用16位字长更好,所以就有了uint_least16_t。
