Is it:-

a.) int random_number;

random_number = 666;

-or-

b.) int random_number = 666;

?

Either way will work, so there is no INcorrect way.

If the variable needs to be initialized to a certain value then use b.

If it will be set to a value later in the program (maybe a return value from a function) then

int random_number; .

...

random_number = rand();

would be best.

b

Is it:-

a.) int random_number;

random_number = 666;

-or-

b.) int random_number = 666;

?
