Question

What is a local variable? How is access to a local variable restricted?

Short answer

#Short_Answer# A local variable is a variable declared inside a function or any block of code and can only be accessed within that specific scope. It is limited in scope and visibility, meaning it cannot be accessed from outside the function or block where it is declared. Consequently, trying to access a local variable outside its defined scope will lead to a compilation error.

Step-by-step solution

Definition of Local Variable

A local variable is a variable declared inside a function or any block of code, such as a loop or conditional statement. The variable can only be accessed within the scope of that function or block and is destroyed once the execution of that function or block ends.

Scope of Local Variable

The scope of a local variable is limited to the function or block of code in which it is declared. It is not visible or accessible from outside that function or block. For example, if you declare a local variable inside a function 'A', you cannot access that variable from another function 'B' or the main program.

Access Restrictions of Local Variables

Access to a local variable is restricted due to its limited scope. A local variable can only be accessed within the function or block of code where it is declared. Attempting to access a local variable outside of its scope results in a compilation error, as the variable is not recognized outside its defined scope.
