Question

Does "Declaration" allocate memory? (in C language) I google it before, there

are many people said that "Declarations" allocate memory

But in some books it is written that once you declare a variable, you allocate some space for that variable

I tested it too by using pointers
And i saw that Declaration allocates memory

Why is there this disagreement?
