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 vs. macros See also Theinlinekeyword suggests that the compiler substitute the code within the function definition in place of each call to that function. In theory, using inline functions can make your program faster because they eliminate the overhead associated with function calls...
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 ...
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 ...
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;}...

During code optimization, some functions are placed in line. That is, the body of the function is placed directly in the code like a macro expansion. There is no function call and no return to the caller. To facilitate the display of inline functions, the compiler stores data in the PDB...
