local variables are the variables which are declared with in
a function and the scope of that variables are only within
that function.Global variables are the variables which are
declared globally.Since it is declared globally it can
accessible to all the functions inside the program...

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.

Answer / pushpendra

local variable:-its uses inside the function that is these variable exist inside the function and other fu no access out side the main function.
while global variables are variables and which are declared both sides of function inside and outside that is globally.all functions can access out of main function.

Main must be written as a.the first function in the program b.Second function in the program c.Last function in the program d.any where in the program
