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(...
You should use an inline function when you wish to optimize function calls. You may consider an inline function as a macro that copies the function contents (inline) to code segment where the function is called. However, inline function is very different from a macro (google it up). Some ...
Although inline functions are similar to macros (because the function code is expanded at the point of the call at compile time), inline functions are parsed by the compiler, whereas macros are expanded by the preprocessor. As a result, there are several important differences: Inline functions f...
Macro and inline function are very similar. Compiler expands macro where it is called and inline functions are also copied to the place where it is called. They both increase code size as compiler copies object code to the location where these are getting called. However they are not same ...
An inline function in C++ programming is a special type of function defined using the inline keyword. Instead of making a traditional call where control is passed to the function and then returned, an inline function's code is directly inserted into the place where the function is called. ...
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;}...

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....
