* getch() :-  getch(); is a non standard function and is present in < conio.h > . It hold the output window ,till the user feed input or press any key from the keyboard.  (input a number on keyboard to get back to your program )

*getche() :-  getche (); this is a non standard function which is present in <conio.h>  . It reads the single charcter from the keyboard and display immediately on output screen without waiting for enter key.

* getchar() :-  getchar(); is the function which is used to get/read a character from keyboard input. We can use getchar function as    --        getch(char);

*Main function :- The mai  function is the entry point of any C program. This contains two part declaration part & executable part.

*Operating system :- It is a inter phase  or bridge between user and computer  or  between hardware and software

*Compiler :- The compiler converts source code into machine code at one.

*Interpreter :- The interpreter converts source code into machine code line by line.

*Headerfile :- The collection of pre define function which is already exists in library.

*Gobal variable :- The global variable that can be use anywhere in the program.

*Local variable :- The variable which is use for local scope , within the block {.....}

*Operators :- The operator are sign which is use for generate and an expression.

*Documentation section :- The documentation section consist of a set of comment line giving the name of program and other details.

*Comments :-A comments is an explanation or description of the source code of the program. It helps a developers explains logic which of the codes and improve program readability . At run time compiler ignores comments.

*Character sets :- A character sets in C programming is sets of all valid character that can be used to form words ,numbers,and expression in source program.

*Array :- Array is the collection is of homogeneous data items that share a common name . Array contains similar kind of value on a same name it allocate contiguous and sequential memory . Array have some many other things which we discuss our next post.
