A function declaration serves as a hint to the compiler that a particular function exists. Answered aug 4, 2013 at 23:09. The parameter type (s) function prototypes are a good practice in c and they help you expand your code without any unforeseen errors due to the compiler not knowing a function signature. A function prototype gives information to the compiler that the function may later be used in the program.
In computer programming, a function prototype is a declaration of a function that specifies the function's name and type signature ( arity, data types of parameters, and return type ), but omits the function body. To write a prototype, or to write the function itself (called a definition.) a definition is always a declaration, but not all declarations are definitions.

A function declaration precedes the function definition and specifies the name, return type, storage class, and. Functions are an essential component of the c programming language. To use these functions we need to include the header file in our program. You write prototypes in addition to the functions themselves in order to tell the compiler about the function that you define elsewhere:
The function itself might be defined either in a different compilation unit or later on in the same compilation unit. Web c standard library functions. A function declaration serves as a hint to the compiler that a particular function exists.
Function Prototypes Are Important Because They Inform The Compiler Of The Function's Interface Before It Is Called, Allowing For Proper Type Checking And Error Handling.
