Question

What is the difference between:

char fast_car[15]="Bugatti";

and

char fast_car[15];
fast_car="Bugatti";

Because the second one results with compile error:

error: incompatible types when assigning to type ‘char[15]’ from type
‘char *’

While the first one works fine. Putting a string in array in different place than array initialisation would be helpful.

Answer 1

The first is an initialization while the second is an assignment. Since arrays aren’t modifiable values in C you can’t assign new values to them.

Mind you, you can modify array contents, you just can’t say fast_car = .... So the contents are modifiable, the arrays themselves are not.

Using the same symbol = for these widely different concepts is of debatable value.
