Storage Classes in C-A Storage Class defines the scope (visibility) and life time of variables and/or
functions within a C Program..Two types of storage classes are there in c as explained below
1. Auto
2. Static
1. Auto
2. Static
3. Extern
4. Register
auto is the default storage class for all local variables.
{
int Count;
auto int Month;
}
The example above defines two variables with the same storage class. auto can
only be used within functions, i.e. local variables.

Register - Storage Class-Register is used to define local variables that should be stored in a register instead
of RAM. This means that the variable has a maximum size equal to the register size (usually one word) and cant have the unary '&' operator applied to it (as it does not have a memory location).Fast access but limited.Reside in CPU registers details.
