syntax of c programming language

C language is developed by Dennis Ritchie.

Points to be remember while writing c program

1) every programming instruction must be returned within a main block.

2)All the instructions must be returned in a lowercase, because she is a case sensitive language it knows the difference between lowercase and uppercase.

3) every statement must be ended with a semicolon (;).

4)we May write constant variable or any user-defined thing in capital.

Steps to save ,compile and execute the program

1) save: File->save (F2) i.e first.c

2) compile and execute:Ctrol+F9

Note: if getch () is not there, then we can see the output screen using alt+F5, else directly we can see the output.

Example:

Syntax

Main ()

{           Clrscr();

             Printf("My first program in c.");

             getch ();

}

    Where

            Clrscr (): used to clear the screen.

            Printf ():  to display the text o value of variable on the                                                                     screen.

            getch ():  is used to hold output screen.                                    

Escape Sequences: is used to move the cursor on the particular position

'\n'(newline)           : is used to jump the cursor on the next line.

'\t'(tab)                   : to Move Cursor 5 characters along.

'\r'(carriage return):to move the cursor on the first character of the                                     current line.

'\b'(backspace)       : to jump the cursor one character left.
