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。
An inline function in C++ prompts the compiler to insert or in-line the code whenever the function is called. This reduces execution time and overhead function call times. We use the inline keyword to define these functions. 23 mins read ...
In C, we have usedMacrofunction 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 especially t...

A member function can also be declared as inline function, use the inline keyword before function declaration and definition, if function definition is written outside of class. Example In the below example,square()andaverage()are the inline functions inside the class (with in the class). ...
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...
Use the/Obcompiler optimization option to influence whether inline function expansion actually occurs. /LTCGdoes cross-module inlining whether it's requested in source code or not. Example 1 C++ // inline_keyword1.cpp// compile with: /cinlineintmax(inta,intb){returna < b ? b : a; } ...
A function definition in a class definition is an inline function definition, even without the use of the inline specifier.ExampleFollowing is an example, which makes use of inline function to return max of two numbers −Open Compiler #include <iostream> using namespace std; inline int Max(...
Inline function is like a macro definition. When it was be called in another function, the control right will not be changed to this function. The compiler will just replace the line of inline function with the actual content of the function. We use inline function to eliminate the cost of...
