extern is a keyword that is prefixed in function
declaration. It means tht function definition is in source
file.
for eg.
source file contains int sum(int x,int y) definition part.
To make use of this function in file by simply declare as
extern int sum(int ,int); is a good practice.
But to compiler happy extern sum(); is enough.
