Answer:
many forms
Explanation:
Polymorphism is a construct in object oriented programming which means multiple forms.For example: Suppose I have a function which performs the add operation on two integers and another function with the same name which concatenates 2 given strings:
- string add ( string a , string b)
The two functions represent polymorphic forms of the add function. The function to be invoked at runtime is determined by the runtime argument type.
For example , add (2,3) will invoke int add ( int a, int b);
Similarly, add("hello","world") will invoke string add ( string a , string b);
Answer:
a. (p*Main).age = 20;
Explanation:
Pointers use ->
where as normal variable use . to access its members
pMain is the pointer.
*pMain is the value inside pMain.
pMain->age = 20;
This statement equals to
(*pMain).age = 20;
