CBSE Class 12 Computer Science Object Oriented Programming Worksheet

Q1. Give an example of polymorphism.
Ans. Polymorphism (overloading) Function overloading If a function name is same and use more than one time with different parameters is called function overloading.
void num( )
{
int a;
a= 5*10; }
void num1 (int a)
{
int b;
b= a*a;
return;
}

At calling time we can also overload the functions

Q2. Write 4 advantages of Object oriented programming.
Ans. Advantages of OOP
1. Re-use of code
2. Based on comprehensive approach
3. Program can be maintained using encapsulation and hiding of data
4. Easy to maintain , cost effective
5. Easy to redesign and easy to extend

Q3. Illustrate the concept of function overloading with the help a function namely Area that return a float type value
Ans. A function name having several definitions that are differentiable by the number of types of their arguments, is known as function overloading. For example, following code overloads a function area to compute areas of circle, rectangle and triangle.
float area (float radius) // for computing area of a circle
{
return 3.14 * radius * radius;
}
flaot area ( float length , float breadth) // for calculation area
{
return length * breadth;
}
