Hi, i've got problem with function pointer, the program crash when i try to run, compiler is OK (gcc version 4.3.2). thanks a lot for any helping.
Code:#include <iostream> class one { public: int min(int a, int b) { if (a < b) return a; else return b; } int guru() { int (one::*func)(int, int) = NULL; return (*this.*func)(2,3); } }; int main() { one o; o.guru(); // crash return 0; }
Perhaps you meant to write:
Code:int (one::*func)(int, int) = &one::min;

You seem to be pointing at NULL, not min.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
It's work, thanks very much.
