如何使 MinGW 将诸如“文本”之类的文本视为 const char*

Question

AFAIK, after upgrading to MinGW 4.4. * some time ago all of my literally written strings (like "i'm the string" ) are treated as of the type std::string . Is there any command line option to make MinGW treat them as const char* as it was before?

Answer 1

Strings are per default char * / char[] in C / C++, only if you explicit say its a std::string you'll get those.

Example:

std::cout << "first:\t" << typeid("aa").name() << std::endl;
std::cout << "second:\t" << typeid(std::string("a")).name() << std::endl;

Output:

first:  A3_c
second: Ss

Result:

• first: a char array with length of 3 (= 2 chars + end)
• second: is a std::string

As you can see, if you write "abc" you wont get a std::string .

But: if you write std::string str = "abc" you get a std::string because the asignment operator ( = ) is used: string& operator= (const char* s)
