C specials and its Special considerations
Functions
These are the routine (established coding) written in C language and stored in the object complier software program to do some intended task or function in a prescribed manner which was established by writing these coding and stored with a name called C function.
Example : “Get char” is a function loaded in to receive input from key board as one by one character key and it is being done by us sticking a key in the key board.
Example: “Scanf” is a function loaded in to receive input from key board continuously to allocate to a variable or any other memory variable continuously at a stitch with the strike of enter character key at the end and it is being done by us sticking keys in the key board.
These are called built in functions in C library
Include
This is the primary section in which what ever header files you need to use while runnig your program in C you are adding in your program for ready reckoned use when needed while compiling for object program. These header files also pre coded small programs linked with compiler software program. Header files are included by writing these at the beginning of the program with Hash symbol. It is the syntax for writing it.
Example: # include ‘stdio.h’
In this we are adding the header file with a name stdio.h which is available in C complier. The purpose of this is to linking the standard input output header file. To get and store input data and output data in a system as per C instruction set.
