把成员函数以指针形式传递问题请教~~~~~
C/C++ code
#include<stdio.h>typedef int (*printfun)(char *str);class A{public: void ap(printfun pf) { pf("aaaaa"); printf("calss A\n"); }};class B{public: int print(char *str) { printf("class B : %s\n",str); } void bp() { A a; a.ap(print); }};void main(){ B b; b.bp();}
vc6下编译错误: C:\Documents and Settings\Administrator\test.cpp(27) : error C2664: 'ap' : cannot convert parameter 1 from 'int (char *)' to 'int (__cdecl *)(char *)' None of the functions with this name in scope match the target type
