- Statement A declares the address of a structure containing the
members plot, street and city.
- Statement B declares a structure having 3 members: name, marks,
and adr. The data type of adr is structure address, which is given by
statement C.
- Statement D defines the variable student1 of the data type struct
student.
- Statement E defines an array class with 20 elements. Each element
is a structure.
- You can refer to marks of the students of class[1] using the
notation class[1].marks. class[1] indicates the first element of the
array, and since each element is a
structure, a member can be accessed using dot notation.
- You can refer to the plot of a student of class[1] using the notation
class[1].adr.plot. Since the third element of the structure is adr, and
plot is a member of adr, you can refer to members of the nested
structures.
- If you want to refer to the first character of the character array
plot, then you can refer it as
8.
Class[1].adr.plot[0]
because plot is a character
array.
