Question

Given the C++ statement alpha[i]->beta = 13.5; what do you know about alpha?

Answer 1

There is a structure array which has float/double variable named beta as data member. And, Alpha is a pointer holding the structure array.

Explanation :-

alpha[i] shows that it is array

aplha[i]->; -> shows that it is pointer as the structure members are accessed with -> through pointers

aplha[i]->beta shows that it is structure and it has a member named beta.

beta=13.5 tells that it is double/float type.
