The example below showcases the implementation of an inline function in C++. Code Example: #include<iostream> using namespace std; // Use the keyword "inline" to define an inline function inline int sum(int a, int b) { // Definition of inline function return a + b; } int main() {...

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...
In some of the cases, the program's performance may slow down. Based on the function code complexity, the compiler may ignore the inline keyword. Thus, the application of the inline function is limited. Some of the disadvantages of inline function are as follows − ...
Consider the below example to create class with inline functions in C++.#include <iostream> using namespace std; // defining class class Student { private: // data members int english, math, science; public: // inline constructor function Student(int english, int math, int science) { this...
Example 1C++ Copy // inline_keyword1.cpp // compile with: /c inline int max(int a, int b) { return a < b ? b : a; } A class's member functions can be declared inline, either by using the inline keyword or by placing the function definition within the class definition....
在编译C++程序时,每一个TU内inline function的定义都会被编译出来,接着在连接时,利用linker来处理程序中不同TU里对同一个inline function的多个定义,一般是保留其中的一个,这时为了避免UB,C++要求不同定义的行为是一致的。请看下面例子: // a.cpp #include <stdio.h> extern inline void f() { printf("lll...
EXAMPLE_H // function included in multiple source files must be inline inline int sum(int a, int b) { return a + b; } #endif // source file #2 #include "example.h" int a() { return sum(1, 2); } // source file #1 #include "example.h" int b() { return sum(3, 4); ...
This copies the function to the location of the function call in compile-time and may make the program execution faster. Before following this tutorial, be sure to visit the C++ Functions. Inline Functions To create an inline function, we use the inline keyword. For example, inline returnType...
See the following example: -qinline+increase -qinline-decrease -qinline=noauto:level=5 In C++, you can use the -qinline+ and -qinline- options in the same way as in example 2; however, you must specify the mangled function names instead of the actual function names after these options...
