What are the functions of a storage class?
There are four storage class specifiers in C and C++. These are - 1. auto : The storage specifier auto refers to automatic variable declaration. The life of an automatic variable is the time during which its parent function is running. The scope of an auto variable is the function scope. They can be accessed only from their parent functions. Syntax : auto int a; 2. register : A register variable has all the characteristics of an auto variable. The only difference is that auto variable uses the main memory to store data and register uses the CPU registers. 3. extern : This storage specifier is used to declare a global variable. The life of these variables is the time during which the program runs.
If you don't supply any access specifier with class name than which specifier it should have?
It will have the default access which means - this class will be accessible only within the current package.
Storage classes available in c language?
There are four types of storage class or variable in c. 1) auto storage class. 2) register storage class. 3) static storage class. 4) external storage class.
What value is assigned to extern variable?
Default initial value of extern integral type variable is zero otherwise null.
Is the default access specifier same as protected?
A private member of a class can only be accessed by methods of that class. A protected member of a class can only be accessed by methods of that class and by methods of a derived class of that class.

Storage class specifier.
What is the difference between an auto storage class and a register storage class in c?
The register storage class specifier is typically used for a heavily-used primitive data type, such as a loop control variable, and indicates to the compiler that this variable should be stored in a machine register to reduce access time. However, there are very few registers available and they are limited in size, so the compiler is free to ignore the specifier, in which case the variable is treated as if it were specified as an auto storage class. The auto storage class specifier allows you to explicitly declare a variable with automatic storage. Such variables are treated as being local to the block, and will fall from scope when the block ends. Since this is the default behaviour of all local variables, the auto specifier is redundant.
How the jvm is able to access your class even you declare it using default access specifier but the same class is not accessed from other class which is declared in another package?
The JVM knows about all of your classes, no matter what package they are in or what access specifier you declared them with. The access specifier is only used to limit access from other classes.
Explain the different access storage specifiers available in c?
The storage class specifiers in C and C++ are:autoexternmutableregisterstatictypedefA storage class specifier is used to refine the declaration of a variable, a function, and parameters
What is mistake if you get error that declaration has no storage class or type specifier?
bad: x; static y; good: int x; static float y;
What is the use of public access specifier?
use of public access specifier iswe can access the class members(methods,variables) out side the class using class reference

What is private specifier in c plus plus?
The private specifier states that the member can only be accessed by the containing class, and not by any derived class, nor by any other code outside of a class.

It will have the default access which means - this class will be accessible only within the current package.

Which is public to all access class or struct or function or variable?
The default access specifier for a class is private. The default access specifier for a struct is public. It does not matter if it is a function or a variable.
What value is assigned to extern variable?
Default initial value of extern integral type variable is zero otherwise null.
