NOTE:A variable stored in CPU register can always be accessed faster than the one which is stored in memory. We cannot use register storage class for all types of variables. Example:register double a; ,register float c; etc. 3) Static storage classes ...
There are 4 types of storage classes in C: auto register extern static 1. auto It is the default storage class for every local variables. When a function is called they are created and when the function exits they are destroyed automatically. Example void main(){ int data; auto int data...
There are broadly four storage classes in C: auto, external, register and static. Auto: In the language C auto is a keyword for specifying a storage duration. When you create an auto variable it has an “automatic storage duration”. We call these objects “local variables”. Auto variables...
C Storage Classes Explained - Learn about the different types of storage classes in C programming, including automatic, external, static, and register storage classes.
There are 4 storage classes in C: auto register static extern At least a few of these will look familiar to anyone who has done a cursory amount of Objective-C programming. Let’s go into more detail with each one: auto There’s a good chance you’ve never seen this keyword in the ...
From the above-mentioned concept of C language storage classes, it is clear to the reader that whenever we manage data through software, we need some variable or storage space to store the data. We now have a clear idea from this article about how the data is to be stored in a variable...

Storage Classes are used to determine in which space the value of variable will Stored. And what will be the value of variable, when we doesn’t Specify the value of variable. And In what Place we can use the value of variable. The Storage Classes Determ
However, in some applications it may be useful to have data which is accessible from within any block and/or which remains in existence for the entire execution of the program. Such variables are calledglobal variables, and the C language provides storage classes which can meet these requirements...
