Whenever aninlinefunction is added to or changed in a header file, every source file that uses that header must be recompiled. 在头文件中加入或修改inline函数时,使用了该头文件的所有源文件都必须重新编译。
So inline member functions should be declared and defined in the same header. In other words, the inline function should (not must) be placed in the header file instead of the cpp file. An identical definition for the function must exist in every translation unit that uses that line ...
In theory, using inline functions can make your program faster because they eliminate the overhead associated with function calls. Calling a function requires pushing the return address on the stack, pushing arguments onto the stack, jumping to the function body, and then executing a return instruc...

3) It may cause compilation overhead as if some body changes code inside inline function than all calling location will also be compiled. 4) If used in header file, it will make your header file size large and may also make it unreadable. 5) If somebody used too many inline function re...
When a function is only called by other functions in same file, make it a static function. This will allow the compiler to inline functions better. 2 When a global variable is only used by functions in the same file, make it a static variable. 3 Group minor functions in a single file...
Inline code substitution occurs only at the compiler's discretion. For example, the compiler won't inline a function if its address is taken or if it's too large to inline. When the compiler doesn't inline a function defined in a header file, it's marked for the linker to avoid one-...

Assuming I have defined a function 'f' in header file and include the header in two different files: a.cpp and b.cpp. Like: void f() {} You'll get the following error when compiling (cl a.cpp b.cpp): b.obj : error LNK2005: "void __cdecl f(void)" (?f@@YAXXZ) already de...
cout << "The inline function sum() returned: " << result << endl; return 0; } Output: The inline function sum() returned: 40 Explanation: In the simple C++ program, we begin by including the essential header file <iostream> for input-output operations and use namespace to avoid pref...
