在C++中,string literal的型别并不是std::string,而是C语言的const char*,也就是const char array,之所以能直接写std::string str = "C++" 或 str::string str("C++"),是因为std::string的copy constructor帮我们将const char*转成std::string,反之,有的函数只能用const char*,如IO的ifstream(),若是std:...
Strings can be initialized directly by assigning a string literal to a char array. For example: chargreeting[]="Hello, world!"; In this case, the C compiler automatically appends the null terminator at the end of the array. Initializing using character arrays ...
String literal objects are initialized with the sequence of code unit values corresponding to the string literal’s sequence ofs-char sandr-char s(since C++11), plus a terminating null character (U+0000), in order as follows: ...

In Visual C++ you can use a string literal to initialize a pointer to non-const char or wchar_t. This is allowed in C code, but is deprecated in C++98 and removed in C++11. An attempt to modify the string causes an access violation, as in this example: ...
A literal string in C code is placed in the data segment. Whether that is a writable segment or a read-only segment depends on the C compiler and the options given to the C compiler. Perhaps the real issue is when one passes a string pointer to a subprogram when that subprogram writes...

第一种的第二是将字符数组初始化为字符串的方法—只需使用一个用引号括起的字符串即可,这种字符串被称为字符串常量(string constant)或字符串字面值(string literal) chardog [8] = {'b','e','a'};// not a string!charcat[B] = {'f','a','t','\0'} ;// a string!charbird [11] ="Mr...
