The Video all about the types Inheritance in C++. There are five types of Inheritance provided by C++. They are: – Single Inheritance, Multilevel Inheritance, Multiple Inheritance, Hierarchical Inheritance and Hybrid Inheritance. In single inheritance there is only one base class and one derived class. In multilevel inheritance a class can be derived from derived class also. In multiple inheritances a class can inherit the features of two base classes. In hierarchical inheritance a base class can use by many sub classes. While the hybrid inheritance is the mixture of two or more inheritances.

The Video all about the Comparison between FCFS scheduling and SJF Scheduling Algorithm. In First Come First Served (FCFS) Scheduling scheme, the process that requests the CPU first is allocated the CPU first. The average waiting time under the FCFS policy is very long. While in Shortest-Job First (SJF) Scheduling scheme, job requiring the minimal CPU time is selected first for CPU allocation. SJF provide minimum average waiting time in compare to FCFS. Hence this is the optimal algorithm.
