An external definition is an external declaration that is also a definition of a function (other than an inline definition) or an object. If an identifier declared with external linkage is used in an expression (other than as part of the operand of a sizeof or _Alignof operator whose result...
Declaration:the function's name, return type, and parameters (if any) 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 ...
As discussed in the syntax above, an inline function in C++ is declared using the inline keyword, and its definition must typically be placed near the declaration. The process for defining an inline function in C++ is as follows: Declaration/Definition Location: An inline function is often decla...

A function definition consists of a declaration, plus thebody, which is all the code between the curly braces: C++Copy intsum(inta,intb){returna + b; } A function declaration followed by a semicolon may appear in multiple places in a program. It must appear prior to any calls to that...
