The process for defining an inline function in C++ is as follows: Declaration/Definition Location: An inline function is often declared and defined at the beginning of the structure of C++ program, but it can also be defined inside a class or a structure. Function Call: After the function ...
NOTE- This is just a suggestion to compiler to make the function inline, if function is big (in term of executable instruction etc) then, compiler can ignore the “inline” request and treat the function as normal function. 什么是内联函数: 内联函数是一种C++增强功能,可以增加程序的运行时间。

In many places we create the functions for small work/functionality which contain simple and less number of executable instruction. Imagine their calling overhead each time they are being called by callers.When a normal function call instruction is encountered, the program stores the memory address ...

Inline templates appear as normal function calls in the C/C++ source code. When the source code program cc -O prog.c code.il and the file containing the inline template defining the function are compiled together, the compiler will insert the code from the inline template in place of the ...
In C, we have used Macro function an optimized technique used by compiler to reduce the execution time etc. So Question comes in mind that what’s there in C++ for that and in what all better ways? Inline function is introduced which is an optimization technique used by the compilers ...

1. An inline function is defined by the inline keyword. Whereas the macros are defined by the #define keyword.2. Through inline function, the class’s data members can be accessed. Whereas macro can’t access the class’s data members.3. In the case of inline function, the program can...
