c++ - How does function-style cast syntax work?

Question

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

I guess I am a bit puzzled by the syntax. What does the following mean?

typedef char *PChar;
hopeItWorks = PChar( 0x00ff0000 );

It is equivalent to (PChar) 0x00ff0000 or (char *) 0x00ff0000. Syntactically think of it as invoking a one-argument constructor.
