BASIS FOR COMPARISON	LOCAL VARIABLE	GLOBAL VARIABLE
Declaration	Variables are declared inside a function.	Variables are declared outside any function.
Scope	Within a function, inside which they are declared.	Throughout the program.
Access	Accessed only by the statements, inside a function in which they are declared.	Accessed by any statement in the entire program.
Life	Created when the function block is entered and destroyed upon exit.	Remain in existence for the entire time your program is executing.
Storage	Local variables are stored on the stack, unless specified.	Stored on a fixed location decided by a compiler.
