Definition:the body of the function (code to be executed) voidmyFunction(){//declaration // the body of the function (definition) } For code optimization, it is recommended to separate the declaration and the definition of the function. ...
一个external definition 就是一个 定义了函数或者对象的external declaration(除了 inline definition) 如果一个 external linkage 的标识符 出现在表达式中,整个程序的某个地方应该存在一个 这个标识符的external definition ;相反,最多 只能有 1 个(这样,具有external linkage 的标识符不用在表达式中,不需要这个标识...
Afunction definitionconsists of the declaration and the function body, enclosed in curly braces, which contains variable declarations, statements and expressions. The following example shows a complete function definition: C++ intfoo(inti,std::strings){intvalue {i}; MyClass mc;if(strcmp(s,"default...
In any case, the function is always visible from the definition point to the end of the file.The optional declaration-specifiers and mandatory declarator together specify the function's return type and name. The declarator is a combination of the identifier that names the function and the ...

The deleted definition of a function must be the first declaration in a translation unit: a previously-declared function cannot be redeclared as deleted: struct T { T(); }; T::T() = delete; // Error: must be deleted on the first declaration User-provided functions A function is user...
