difference between assignement and initialisation

[sushant]

hi all,

whats the difference between assignement and initialisation in C.
is assignement related with scanf() and initialisation with (int x=10;)

Initialisation is, you give a value during the creation of the
variable, like this:
int i = 10;

Assignment is that you give the variable some value after it got
created, like this:

int i; /*Creating the variable, but may have garbage value */
i = 10; /* Assigning 10 to the integer variable i*/

is assignement related with scanf() and initialisation with (int

x=10;)
To some extent yes, but may cover other scenarios too.

Initialization is the specifying of a value for an
object at the time you create it. Assignment is
the giving of a value to an already existing object.

int i = 10; /* define a type 'int' object, */
/* inititalized with value of 10 */

i = 25; /* assign a value to the already */
/* existing object 'i' */
is assignement related with scanf()
Not directly. However one of the operations 'scanf()'
can do is assign values to objects.
and initialisation with (int x=10;)

Yes, that's the correct syntax for initializing an object.

Which C book(s) are you reading?

Initialize: assign value to a variable as it is declared/crated.

Assignment: assign value to a variable. It doesn't matter in this case
whether the variable was already assigned any value or not.

scanf does assign values to variables and so does various other
operations.
and initialisation with (int x=10;)

Perfect this is intialization.
This is very basic questions in C. I'd rather you go thru your C book
again and again!

HTH.
