Answer 1

Answer:

Header File

Explanation:

Function prototypes are often placed in separate header files, which are then included in the routines which need them.

Answer 2

Answer:

The Function prototype for built-in functions are specified in is (a) header file.

Explanation:

• A header file is the file that is defined with the extension .h and it contains declarations of function and it is shared between sources of files.

• There are two types of header files. They are:

1) Files written by the programmer

2) the files created compiler.

We will use the C program for creating the preprocessing directive.

# include

• A request to use the header files in your program.
• The stdio.h file that is header comes with the compiler.

• Syntax for header file:

The user and the header system files are used using the preprocessing that is #include.

#include <file>

It is used as header for the system files.

It will search for the file named as ‘file’ in directory containing the file that is current.
