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...
The are four storage classes in C: automatic, register, static, and external. Storage class specifiers: auto, register, static, and extern. The storage class of a variable determines its lifetime, scope, initial value, and storage location.
Learn about the different types of storage classes in C programming, including automatic, external, static, and register storage classes.
Storage classes in C Brief description about Storage classes in C According to the storage classes of “c” the lifetime of the auto variable is restricted within the body that’s why how many times we are calling the abc function that many times it will created....
As a result, extern variable will be hidden in that case.3) static The main property of static variables is that they can retain their values even when they are used out of their scope. So, they are able to store the value of their last use in their scope. The static variables are ...

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 ...
Storage class in C Topics Automatic variables External variables Static variables Register variables Scopes and longevity of above types of variables. Few terms Scope: the scope of a variable determines over what part(s) of the program a variable is actually available for use(active). Longevity: ...
