The inline function in C++ programming is a function for which the compiler is requested to insert the function's code directly at the location where the function is called, rather than performing a traditional function call. This approach reduces the overhead associated with function calls, such...
Inline functions follow all the protocols of type safety enforced on normal functions. Inline functions are specified using the same syntax as any other function except that they include theinlinekeyword in the function declaration. Expressions passed as arguments to inline functions are evaluated once....
Inline functions vs. macros A macro has some things in common with aninlinefunction. But there are important differences. Consider the following example: C++ #include<iostream>#definemult1(a, b) a * b#definemult2(a, b) (a) * (b)#definemult3(a, b) ((a) * (b))inlineintmultiply(...
macro Vs inline The C/C++ style, macros without arguments should look like variable or other identifiers, macros with arguments should look like function calls. so any difference between macro and inline? #defineSQUARE(x) ((x)*(x)) inlineintsquare(intx) {returnx*x;} macro may not work ...

The effect is roughly the same as defining a standard function inline; calls to the function are expanded into inline code, much like a macro. This is principally useful as a way of supporting C++ classes in a DLL that might inline some of their member functions for efficiency....
Can a pure virtual function have an implementation? 转自:http://www.programmerinterview.com/index.php/c-cplusplus/pure-virtual-function/ The quick answer to that question is yes! A pure virtual function can have an implementation in C++ – which is something that even many veteran C++ develope...
