cout << "The inline function sum() returned: " << result << endl; return 0; } Output: The inline function sum() returned: 40 Explanation: In the simple C++ program, we begin by including the essential header file <iostream> for input-output operations and use namespace to avoid pref...
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。
When a normal function call instruction is encountered, the program stores the memory address of the instructions immediately following the function call statement, loads the function being called into the memory, copies argument values, jumps to the memory location of the called function, executes th...
Simple, function calls are simply more time consuming than writing all of the code without functions. To go through your program and replace a function you have used 100 times with the code from the function would be time consuming not too bright. Of course, by using the inline function to...
In many places we create the functions for small work/functionality which contain simple and less number of executable instruction. Imagine their calling overhead each time they are being called by callers.When a normal function call instruction is encountered, the program stores the memory address ...

The function must also be compiled as usual if the program refers to its address, because that can't be inlined. static inline function中是可以使用声明被static修饰的标识符或函数的,现在假设以下场景:有三个文件header.h, test.c, test1.c 。在header.h中包含了static inline funciton: f(),在f...
As you can see, this program is really just a simple inline function hook, no more complex than the example from Chapter 5. 就这样了。可以看到,这个程序不过是个简单的内嵌函数挂勾,不比第5章的例子复杂多少。 www.pkwall.com 3. Therefore, each inline image on the Web page means that there...
