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() {...
To create an inline function, we use theinlinekeyword. For example, inlinereturnTypefunctionName(parameters){// code} Notice the use of keywordinlinebefore the function definition. C++ Inline Function #include<iostream>usingnamespacestd;inlinevoiddisplayNum(intnum){cout<< num <<endl; }intmain()...

ExampleIn the following example, we are defining an inline function with the class −Open Compiler #include <iostream> using namespace std; class Number { private: int num1; int num2; public: // Function to set the values void setValues(int a, int b); // Function to print the ...
class ForwardReference { int i; public: // call to undeclared function int f() { return g()+10; } int g() { return i; } }; int main() { ForwardReference fr; fr.f(); } You must be thinking that this will lead to compile time error, but in this case it will work, because...
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); ...
Example 1C++ Копиране // 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 ...
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 The Point class, introduced in Function-Call Results can be optimized as follows: 複製 // when_to_use_inline_functions.cpp class Point { public: // Define "accessor" functions as // reference types. unsigned& x(); unsigned& y(); private: unsigned _x; unsigned _y; }; inline...
Example In the following class declaration, theAccountconstructor is an inline function. The member functionsGetBalance,Deposit, andWithdraware not specified asinlinebut can be implemented as inline functions. Copy // Inline_Member_Functions.cpp class Account { public: Account(double initial_balance) ...
