1、什么是sizeof 首先看一下sizeof在msdn上的定义: The sizeof keyword gives the amount of storage, in bytes, associated with a variable or a type (including aggregate types). This keyword returns a value of type size_t. 看到return这个字眼,是不是想到了函数?错了,sizeof不是一个函数,你见过...

Both string::size and string::length are synonyms and return the same value. C++中对size的解释 Return length of string Returns the length of the string, in terms of bytes. This is the number of actual bytes that conform the contents of the string, which is not necessarily equal to its ...
Size of string literals For ANSIchar*strings and other single-byte encodings (but not UTF-8), the size (in bytes) of a string literal is the number of characters plus 1 for the terminating null character. For all other string types, the size isn't strictly related to the number of cha...
