Question

Define Global scope with an example.

Answer 1

Global Scope:

A variable that is declared outside of all the functions in a program is known as a global variable. This means a global variable can be accessed inside or outside of all the functions in a program. Consider the following example 

On execution of the above code the variable a which is defined inside the function displays the value 7 for the function call Disp( ) and then it displays 10 because a is defined in the global scope.
