Answer / ashish
Local:-
These variables only exist inside the specific function that
creates them. They are unknown to other functions and to the
main program. As such, they are normally implemented using a
stack. Local variables cease to exist once the function that
created them is completed. They are recreated each time a
function is executed or called.
Global:-
These variables can be accessed (ie known) by any function
comprising the program. They are implemented by associating
memory locations with variable names. They do not get
recreated if the function is recalled.
