What is meant by storage class in C?
Storage Classes are used to describe the features of a variable/function. These features basically include the scope, visibility and life-time which help us to trace the existence of a particular variable during the runtime of a program.
What is the difference between static and extern storage class?
static means a variable will be globally known only in this file. extern means a global variable defined in another file will also be known in this file, and is also used for accessing functions defined in other files.
What is the purpose of storage classes?
A storage class specifier is used to refine the declaration of a variable, a function, and parameters. Storage classes determine whether: The object has internal, external, or no linkage. The object is to be stored in memory or in a register, if available.
What is storage and its types?
There are two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, such as a hard drive. Secondary storage can be removable, internal, or external.
What are the different storage classes in C?
Storage classes in c. Question: Explain the different of storage classes in C? Answer: C has three kinds of storage: static, automatic and allocated. changeable having block scope and without static specifier have automatic storage duration. Variables with block scope, and with static specifier have static scope.
What is the use of storage classes in C?
A storage class in C is used to represent additional information about a variable.
What is storage class in C language?
Storage classes in C. In C language, each variable has a storage class which decides the following things: scope i.e where the value of the variable would be available inside a program. default initial value i.e if we do not explicitly initialize that variable, what will be its default initial value.
What are the different types of storage classes?
There are four types of storage class: automatic, register, external, and static. Storage class defined for a variable determines the accessibility that is what portion of the program could have access to the variable and also the longevity of the variable that is how long the variable would exist.
