Initialization of C array at time other than declaration?

Question

I know in C that I can do the following.

int test[5] = {1, 2, 3, 4, 5};

Now this is only legal when declaring the array. However I was wond

Answer 1

The point is that using int array[]={ } is declaring and initializing the object that you have created.

You can actually assign values to an array after it has been declared:

int array[5];
array[0] = 1, array[1] = 2, ...

What you were doing was assigning several values to one single array entry:

array[5] = {1,2,3,4,5}; // array[5] can only contain one value

This would be legal instead:

array[5] = 6;

Hope this makes sense. Just a question of syntax.
