Explain the motivation behind using a header file for a C program. Solution Motivation behind using header file in c Programming: Header files contain definitions of functions and variables which can be included into any c program by using #include.

The motivation for the introduction of header files is type safety. C allows function calls without forward declaration. Logically speaking using functions without forward declaration is as harmful as using Macros as compilers has no proper mechanism to validate the type of the arguments with the parameters. So chances of unresolved linkage errors and runtime failure is more prominent. 3. Header files are more like data abstraction, you just see the important components and you don\'t need to know the background process. 4. To reduce overhead of RAM....the functions or classes defined in these header files are already compiled so they can be directly used . 5.Including a header allows your code to call functions or methods which are written elsewhere and which may or may not be a part of your software project/build, but which can be found by the \'linker\' when you are building the software. 6. Header files are mainly used to declare and include the signatures (i.e. function name, return value and arguments) of your functions in other files.

1. Explain the motivation behind using a header file for a C program.
Solution
Motivation behind using header file in c Programming:
Header files contain definitions of functions and variables which can be included into any c
program by using #include.
Compilation speed up and optimization :During compilation of some parts of the code it may
be sufficient to load API interfaces from header files to check correctness of the code used while
defining them.
-2. The motivation for the introduction of header files is type safety. C allows function calls
without forward declaration. Logically speaking using functions without forward declaration is
as harmful as using Macros as compilers has no proper mechanism to validate the type of the
arguments with the parameters. So chances of unresolved linkage errors and runtime failure is
more prominent.
3. Header files are more like data abstraction, you just see the important components and you
don't need to know the background process.
4. To reduce overhead of RAM....the functions or classes defined in these header files are already
compiled so they can be directly used .
5.Including a header allows your code to call functions or methods which are written elsewhere
and which may or may not be a part of your software project/build, but which can be found by
the 'linker' when you are building the software.
6. Header files are mainly used to declare and include the signatures (i.e. function name, return
value and arguments) of your functions in other files. The compiler needs to know these
signatures when compiling and linking your files together.
