struct Student stu_1; // define a variable of type struct Student stu_1 struct Student * P; // defined data type struct Student point pointer variable P = & stu_1; // P point stu
If p points to a structure variable stu equivalent:
(1) stu. Member name (such as stu.num)
(2) (* p). Member Name (such as (* p) .num)
(3) p-> member name (e.g., p-> num)
