Is the member function defined in the class definition be automatically as an inline function? Or explicitly add Inline keywords when defining member functions, which will be defined into inline? Actually not! For compilers, the inline function is a request, not a guarantee (C Primer (3ed) P26). The following is taken as an example of code generated under VC 7.0. // Inline inline function demonstration // inlinedemo.h
#pragma overce
#include
Using namespace std;
Class inline {public: // inline? Inline () {cout << "inline construct!" << endl;
// inline? Void setab (int A, int b) {this-> a = a; this-> b = b;} int GETA (); int Getb (); protected: int A, b;};
// inline? inline int inline :: geta () {return a;}
// Non-inline? int inline :: getb () {return b;}
// inlineDemo.cpp: Define the entry point of the console application. //
#include "stdafx.h" #include "inlineDemo.h"
INT _TMAIN (int Argc, _tchar * argv []) {inline inlinea;
Inlinea.seTab (10, 12);
COUT << inlinea.geta () << endl;
Cout << inlinea.getb () << endl;
Return 0;}
