The inline function in C++ programming is a function for which the compiler is requested to insert the function's code directly at the location where the function is called, rather than performing a traditional function call. This approach reduces the overhead associated with function calls, such...
The C++ inline function provides an alternative. With inline keyword, the compiler replaces the function call statement with the function code itself (process called expansion) and then compiles the entire code. Thus, with inline functions, the compiler does not have to jump to another location ...
inline return-type function-name(parameters) { // function code } 另外需要注意的是,inline在某些情况下是失效的: 如果一个函数包含一个循环(for,while,do-while) 如果函数包含静态变量。 如果函数是递归的。 如果函数返回类型不是 void,并且返回语句不存在于函数体中。 如果函数包含 switch 或 goto 语句。

2. C++ inlining is resolved at compile time. Which means if you change the code of the inlined function, you would need to recompile all the code using it to make sure it will be updated 3. When used in a header, it makes your header file larger with information which users don’t...
【inline函数的工作方式】C++ inline functions provide an alternative. In an inline function, the compiled code is 'in line' with the other code in the program. That is, the compiler relaces the function call with the corresponding function code. Within inline code, the program doesn't have ...
1. It increases the executable size due to code expansion. 2. C++ inlining is resolved at compile time. Which means if you change the code of the inlined function, you would need to recompile all the code using it to make sure it will be updated 3. When used in a header, it mak...
Inline code substitution is done at the compiler's discretion. For example, the compiler won't inline a function if its address is taken or if the compiler decides it's too large. A function defined in the body of a class declaration is implicitly an inline function. ...
inline return-type function-name(parameters) { // function code } 此外,inline函数通常放在头文件中,因为大多数build environments在编译期进行inlining,编译器必须知道函数什么样子才能把函数调用替换成函数本体。 大多数virtual函数不能inlining:因为virtual直到运行时才知道调用哪个函数,而inline是在执行前进行替换。
The/Obcompiler optimization option helps to determine whether inline function expansion actually occurs. /LTCGperforms cross-module inlining regardless of whether it was requested in source code. Example 1 // inline_keyword1.cpp // compile with: /c inline int max( int a , int b ) { if( a...
