Q) what is friend function?

 A)  A friend function for a class is used in object-oriented programming to allow access to public, private, or protected data in the class from the outside.
Normally, a function that is not a member of a class cannot access such information; neither can an external class. Occasionally, such access will be advantageous for the programmer. Under these circumstances, the function or external class can be declared as a friend of the class using the friend keyword.

Q) What is the scope of a variable?


 A) Scope refers to the visibility of variables. It is very useful to be able to limit a variable’s scope to a single function. In other words, the variable will have a limited scope

Q) What is a static identifier?


 A)  The static identifier is used for initializing only once, and the value retains during the lifetime of the program/application. A separate memory is allocated for ‘static’ variables. This value can be used between function calls. The default value of an uninitialized static variable is zero. A function can also be defined as a static function, which has the same scope as the static variable.

Q) What exactly is a digital signature?

 A)  Just as a handwritten signature is affixed to a printed letter for verification that the letter originated from its purported sender, digital signature performs the same task for an electronic message. A digital signature is an encrypted version of a message digest, attached together with a message.

Q) What is the difference between an array and a list?

 A) The array is a collection of homogeneous elements. The list is the collection of heterogeneous elements.
Array memory allocated is static and continuous. List memory allocated is dynamic and Random.
Array: User need not have to keep in track of next memory allocation.
List: User has to keep in Track of next location where memory is allocated.
The array uses direct access to stored members, list uses sequential access for members.
