I also want to know what is the purpose of the Automatic storage class in C And how they can work. I also want to know that how can I declare Automatic storage class.

Hi, Automatic storage class variable uses the " auto " keyword. Automatic storage class variables comes into existence wherever and whenever the variable has been declared. Automatic storage class variables are available local to a function. Because of that these varables are also called as local variables. The storage of the Automatic storage class variables is in the memory. Automatic storage class has a default value, which can be garbage value. Automatic storage class variables is local to the block in which it has been declared.

I guess you have heard about the Automatic Storage class in C. Objects of the Automatic Storage class in C are local to block and they are discarded on exit from the block.If there are no storage class section is mentioned or auto specifier is used then declaration within a block can create automatic objects. Automatic Storage class the Object are automatic if they are declared as register and If Possible they are stored in fast registers of the your machine.
Have a Nice Day!

Hi, I think you have to refer the text book of C language for more detailed explanation. auto-Storage class is the default storage class for all the local variables.
{
int Cnt;
auto int Mth;
}
The above example states that two variables with the same storage class. auto keyword can only be used within functions that is a local variables.
