C Programming for Beginners #1 (Getting started)

C Programming is easy to learn there is a close analogy between learning English language and learning C language.
We will start from the basic concept of C like which alphabets,digits,special symbols we can use.

1. Alphabets - A,B.......Y,Z
2. Digits - 0,1,2,3,4,5,6,7,8,9
3. Special symbols - ~ ' ! @ # % ^ & * ( ) _ - + = | \ { } [ ] : ; " ` < > , . ? / $

In C Programming we typically do lots of calculation the result of these calculation is stored in the computer memory it's similar to human memory so all the result in C is in memory location

For now just just keep in mind that in C there are two types of constant:-

1. Primary constant
2. Secondary constant

Primary constant:-

1. Integer constant
2. Real constant
3. Character constant

Secondary constant:-

1. Array
2. Pointer
3. Structure
4. Union
5. Enum.Etc

I'll cover all this topic and using this we are going to learn C programming.

C keywords:-
C keyword are the word whose meaning are already defined in C compiler .There are in all 32 C Keyword as follows:-
auto                       double                           int                              struct             
break                     else                                long                           switch
char                       if                                    register                       typedef        
case                       enum                              return                         union
const                     extern                             short                           unsigned
continue                float                                signed                        void
default                   for                                  sizeof                          volatile
do                          goto                                static                           while

This keyword cannot be used as C variables if we do so we are trying to assign a new meaning to keyword which is not allowed.
Note that different compilers provide their own keyword apart from one mentioned.
