STD: String

A daily struggle with C # Forces C ++ programmers to change their previous code and find the following lines.

Char szpath [max_path] = {0 };

Getmodulefilenamea (null, szpath, sizeof (szpath ));

STD: String strpath = szpath;

STD: String strdir = strpath. substr (0, strpath. find_last_of ('\\'));

I feel uncomfortable. Why are there char arrays and strings? Is it better to use strings.

The following code is changed:

STD: strpath;

Strpath. Reserve (max_path );

Getmodulefilenamea (null, & strpath [0], max_path );

STD: String strdir = strpath. substr (0, strpath. find_last_of ('\\'));

Okay, I have finished modifying. The Nima function has changed... you know .......

Strdir is empty.

For some reason, although there is content in strpath, the API will not assign a value to the size of string.

If you want to use string to replace the char array correctly, you can only use the following method.

STD: strpath;

Strpath. Resize (max_path, 0 );

Getmodulefilenamea (null, & strpath [0], strpath. Size ());

Strpath. asign (strpath. c_str (); // assign a value again.

This... isn't it because you have put your pants on?
