what is the difference between declaration ,defenetion and
initialization of a variable?

Answer Posted / harshit

there is no practical such as declaration its in theory only
the only practical application is :

int a; //defination
a=10; //intialization

this is a normal thing we do,,,now

somemethod()
{
int a;//defination
}


main()
{
extern int a;//declaration
a=10//intialization
}

here we declare that there is a variable "a" somewhere
n this is the only use of declaration ...
to best of my knowledge...
plz suggest if someone kno better
