An operator is a symbol that “operators” on one or more expressions, producing a value that can be assigned to a variable. C has a rich set of operators which can be classified as
• Arithmetic Operators: There are following arithmetic operators supported by C language:
• Logical Operators :-C has the following logical operators, they compare or evaluate logical and relational expressions.
• Assignment Operators :- The Assignment Operator evaluates an expression on the right of the expression and substitutes it to the value or variable on the left of the expression.
• Relational Operators :- Often it is required to compare the relationship between operands and bring out a decision and program accordingly.
• Increment and Decrement Operators :- The increment and decrement operators are one of the u nary operators which are very useful in C language.
• Conditional or Ternary Operator :-The conditional operator consists of 2 symbols the question mark (?) and the colon

when one class acquires the properties of another class then this concept is called inheritance. This is used for reuse the existing functionality.
For Example: children acquire the properties of their parents.
New class is called sub class and existing class is called super class.

In this Video, Shikha Khullar, Asst. Professor, IT Dept, Biyani Group of Colleges explains the Instruction Set. We have two type of Instruction set , CISC stands for Complex Instruction Set Computer .It takes complex and variable size instruction . It uses various addressing methods. RISC stands for Reduced Instruction Set Computer. In this fewer instruction and fixed length instruction.

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.

This Video Lecture given by Mr. Gajendra Sharma, Assistant professor, Biyani girls College, jaipur has covered the various characteristics of Computers and because of these characteristics the computers have become an integral part of the Society and are playing vital role in working environment. And these characteristics include Speed, Accuracy, Diligence, Storage Capacity, Versatility.

In this Video, Miss Komal Mehna is explaining to students regarding VLSI Design Flow. It explains the various design steps for design a chip. VLSI Design flow is bidirectional approach i.e it follow both top-down and bottom-up approach.

This topic s related with the subject microprocessor & microcontroller. Stack is a part of RAM memory, which is used to store the data or binary information temporary for execution of program. Stack is basically worked on LIFO principal. In stack data is store by using push opcode and the data is removed from stack by using pop opcode.
