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 ...

Working of inline functions in C++ Here, we created an inline function nameddisplayNum()that takes a single integer as a parameter. We then called the function 3 times in themain()function with different arguments. Each timedisplayNum()is called, the compiler copies the code of the function...
Using small inline functions may be useful for embedded systems, because inline can yield less code than the function call preamble and return.Disadvantages of Inline FunctionSome of the disadvantages of inline functions are as follows –When we use an inline function, the size of the code is ...

All the member functions defined inside the class definition are by default declared as Inline in C++. Learn more about Inline functions in C++ in this tutorial.
FAQs in section [9]: [9.1] 内联函数有什么用? 当编译器内联展开一个函数调用时,该函数的代码会被插入到调用代码流中(概念上类似于展开#define宏)。这能够改善性能(当然还有很多其它因素),因为优化器能够顺序集成(procedurally integrate)被调用代码,即将被调用代码直接优化进调用代码中。
在.h文件中做了函数inline void f()的声明,在.cpp中做了函数inline void f()的定义。因为编译器在同一时间只能看到一个文件,所以编译器在编译.cpp文件时看到f()前的inline标记,所以不会对f()函数生成代码。但是当编译器编译main.cpp文件时,遇到f()函数时通过其.h文件中的声明知道其是inline函数,却找不到其...
