The document provides an overview of inheritance types in C++, focusing on identification of inheritance types, member accessibility, and class size computation. It outlines various inheritance types including single, multiple, multilevel, hierarchical, and hybrid, along with the rules for accessing members through objects and member functions. The size of a class is explained in terms of the sizes of its data members and its parent classes.
Inheritance question class 12th
- 2. GET 100% MARKS IN COMPUTER SCIENCE TOPIC COVERED : QUESTION BASED ON INHERITANCE
- 3. IN THIS PART 4 TYPE OF QUESTIONS CAN BE FORMED IN YOUR EXAM 1. To Identify the type of inheritance in the given question 2. To identify the members accessible through an object 3. To identify the members accessible through a member function 4. To calculate size of any class
- 4. 3 TERMS CAN BE USED IN THIS TYPE OF QUESTION DATA MEMBERS MEMBER FUNCTIONS/METHODS MEMBERS DATA MEMBERS REFERS TO THE VARABLES DECARED WITHIN CLASS MEMBER FUNCTION/METHOD REFERS TO THE FUNCTION WITHIN CLASS MEMBERS REFERS TO BOTH VARABLES AND FUNCTIONS DECARED WITHIN CLASS
- 5. Q.1 IDENTIFY TYPE OF INHERITANCE TYPES OF INHERITANCE IN C++ ARE 1.) SINGLE 2.) MULTIPLE 3.) MULTILEVEL 4.) HIERARICHAL 5.) HYBRID
- 6. LET’S UNDERSTAND TYPE OF INHERITANCE THROUGH THE MEAN OF DIAGRAMS BASE/PARENT/ SUPER CLASS CHILD/DERIVE D/SUB CLASS SINGLE INHERITANCE BASE/PARENT/ SUPER CLASS BASE/PARENT/ SUPER CLASS CHILD/DERIVE D/SUB CLASS MULTIPLE INHERITANCE BASE/PARENT/ SUPER CLASS CHILD/DERIVE D/SUB CLASS CHILD/DERIVE D/SUB CLASS HIERARICHAL INHERITANCE
- 7. BASE/PARENT/ SUPER CLASS CHILD/DERIVE D/SUB CLASS CHILD/DERIVE D/SUB CLASS MULTILEVEL INHERITANCE BASE/PARENT/ SUPER CLASS BASE/PARENT/ SUPER CLASS CHILD/DERIVE D/SUB CLASS CHILD/DERIVE D/SUB CLASS CHILD/DERIVE D/SUB CLASS HYBRID INHERITANCE
- 8. Q.2TO IDENTIFY THE MEMBERS ACCESSIBLE THROUGH AN OB RULES TO SOLUTION RULE 1: AN OBJECT CAN ACCESS ONLY PUBLIC MEMBERS OF ITS OWN CLASS. RULE 2 : AN OBJECT CAN ACCESS PUBLIC MEMBERS OF IT’S PARENT/SUPER CLASS BUT THE MODE OF INHERITANCE SHOULD BE PUBLIC ONLY.
- 9. Q.3.TO IDENTIFY THE MEMBERS ACCESSIBLE THROUGH A MEMBER FUNCTION RULES TO SOLVE IT EASILY RULE 1: A MEMBER FUNCTION CAN ACCESS ALL MEMVERS/DATA OF ITS OWN CLASS. RULE 2 : A MEMBERS FUNCTION CAN ACCESS ONLY PUBLIC AND PROTECTED OF SUPER/PARENT CLASS IN ANY MODE OF INHERITANCE.
- 10. Q.4. CALCULATE SIZE OF A CLASS • SIZE OF ANY CLASS = SIZE OF THAT CLASS + SIZE OF ITS PARENT CLASSES • TO CALCULATE SIZE OF ANY PARTICULAR CLASS JUST ADD SIZE OF ALL IT’S DATA MEMBERS SIZE OF SOME DATA TYPES INTEGER : 2 BYTES CHARACTER : 1 BYTE FLOAT : 4 BYTES LONG : 8 BYTES DOUBLE : 8 BYTES Note: You have to count size of all data members(variables) including public, private and protected section variables.
- 11. CLASS A CLASS B CLASS C SIZE OF CLASS A ONLY SIZE OF CLASS B + SIZE OF CLASS A SIZE OF CLASS B + SIZE OF CLASS A + SIZE OF CLASS C CLASS A CLASS B CLASS C SIZE OF CLASS A ONLY SIZE OF CLASS B ONLY SIZE OF CLASS B + SIZE OF CLASS A + SIZE OF CLASS C
- 12. CLASS A CLASS B CLASS C SIZE OF CLASS A ONLY SIZE OF CLASS B + SIZE OF CLASS A SIZE OF CLASS C + SIZE OF CLASS A
