Answer:
1.ClassName and . operator
2. ClassName and [] operator
Explanation:
There are two ways to get the members of a class first one is by using dot(.) operator.
Example : with assumption that person is a class object and age is the member in it we can use it as:
person.age
Second way is to use [] operator with member as a string in it which is used by the compiler as key to get its value.
Example : person["age"]
