True

False

​

Answer 1

Answer:True

Explanation:

Answer 2

It's probably what is called the "struct hack". By allocating a large block of memory, the array becomes dynamic. The one element is just a placeholder to make it compile, in fact there will be many floats.

The dynamic array has to be the last element.

Use like this:

struct abc *ptr = malloc(sizeof(struct abc) + (N-1) * sizeof(float));

ptr->variable1 = N; /* usually store length somewhere in struct*/

so yes or true
