As i know.....
Definition is one which allocates memory.
Ex: int x;

Declaration never occupy any memory space.
Ex:Function prototype declarations such as....
int func(int,int);

Initialization: If any variable assigned with some value at
time definition itself is called initialization.
Ex:int x=0;

Answer / shabeer v c

A good example to illustrate this Question ges like this:

Whenever we apply for a job the company declares that we
have been selected. Similarly we declare a variable like

int emp;
(here emp behaves as an employee).

Then he will be assigned with a initial salary which
will be incremented in course of time period or on
experience basis.
Similarly the variable int is assigned a initial
value.
i.e int emp=20;
(value can be changed in between program)

The employee is now identified by his post, which can
define his status in the company.
Same way the variable is also defined in the
program.
ie. int emp;

Answer / nirmal kumar tailor

declaration means you declare variable.
ex: int a;
defination means this integer type a variable take 2 byte
memory space.
initialization means we initialize the value of integer a
variable type.
ex: int a=2;
in declaration we declare variable and variable type , in
initialization we define the value and in defination we
define the type of variable.

Answer / 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
