An inline function in C++ is a special function that reduces call overhead. It signals the compiler to expand the function code in-line where it is called.
注意:本笔记来自网易云课堂学习 内联函数inline function 函数实现的时候需要 pop call 堆栈等 如果函数定义的时候前面加上inline inline int f(int i){…}那么函数就不用之前的那么繁琐的过程了,如上图 inline关键字在,h和,cpp中都要写,因为实际上函数是不存在的,只有inline的形式inline函数的body只在.h文件中...
An inline function is a function that is expended in line when it is invoked, that is the compiler replaces the function call with the corresponding function code. It is the optimization technique used by the compilers. Inline function instruct compiler to insert complete body of the function w...
1、任何定义在类声明中的函数都默认为内联函数。(Any function you define inside a class declaration is automatically an inline) 2、可以在类声明之外用inline定义内联函数,这种方式可以保持类声明的整洁。 ps:建议Access Function(存取函数)一般在类中设为inline。这样在最后生成的代码中其实是主函数直接访问了类...
Use the /Ob compiler optimization option to influence whether inline function expansion actually occurs. /LTCG does cross-module inlining whether it's requested in source code or not.Example 1C++ Copy // inline_keyword1.cpp // compile with: /c inline int max(int a, int b) { return a ...
An inline function isone for which the compiler copies the code from the function definition directly into the code of the calling function rather than creating a separate set of instructions in memory. 从上面的定义可以看出,对于声明为inline的函数,在调用该inline函数的时候,编译器会直接进行代码替换,...
