  • Ans. 

    No, continue statement can only be used inside loops.

    • The continue statement is used to skip the current iteration of a loop.

    Global variables are accessible throughout the program, while local variables are only accessible within a specific function.

    • Global variables can be accessed and modified by any function or module in the program.

    • Local variables are declared within a specific function and can only be accessed within that function.

    • Global variables can cause naming conflicts and make debugging difficult.

    • Local variables are preferred for t...

  • Q5. What do you mean by static variable?
  • Ans. 

    Static variable is a variable that retains its value even after the function execution is completed.

    • Static variables are declared inside a function with the keyword 'static'.

    • They are initialized only once and retain their value throughout the program.

    • They have a default value of 0 if not initialized explicitly.

    • They are useful in situations where we need to maintain the state of a variable across function calls.

  • Q6. Types of polymorphism?
  • Ans. 

    Polymorphism refers to the ability of an object to take on many forms. There are two types of polymorphism: compile-time and runtime.

    • Compile-time polymorphism is achieved through function overloading and operator overloading.

    • Runtime polymorphism is achieved through virtual functions and function overriding.
