With the objectives of spreading Tamil to the entire world through internet, Tamil Virtual University was established on 17th February 2001 by the Govt. of Tamil Nadu. Now, this organisation is functioning with the name "Tamil Virtual Academy". This organisation offers different courses regarding Tamil language, Culture, heritage etc., from kindergarten to under graduation level.

Based on Python programming language, the first Tamil programming language "Ezhil" (cm) is designed. With the help of this programming language, you can write simple programs in Tamil.

No. The return type of overloaded functions are not considered for overloading same data type.

The purpose of the destructor is to free the resources that the object may have acquired during its lifetime. A destructor function removes the memory of an object which was allocated by the constructor at the time of creating a object.

Errors: (); is missing (ii) spaces are missing at two places (iii) structure name given wrongly.
Corrected structure:
struct employee (int eno; char ename [20];
char dept;}
employee e1, e2;

The declaration of a 2-D array is data-type array_name[row-size][col-size];
In the above declaration, data-type refers to any valid C++ data-type, array_name refers to the name of the 2-D array, row-size refers to the number of rows and col-size refers to the number of columns in the 2-D array.

Arguments or parameters are the means to pass values from the calling function to the called function. The variables used in the function definition as parameters are known as formal parameters. The constants, variables or expressions used in the function call are known as actual parameters.
Types : Default arguments and Constant Arguments.

The strelen() takes a null terminated byte string source as its argument and returns its length. The length does not include the null(\0) character.

double x = 10.5, y = 4.5;
int a;
a = int (x) + int (y);

56L- The suffix L forces the constant to be represented as long, which occupies 4 bytes.
56- This will be represented as int type constant which occupies 2 bytes as per Turbo C++.

Character data type accepts and returns all valid ASCII characters. Character data type is often said to be an integer type, since all the characters are represented in memory by their associated ASCII Codes. If a variable is declared as char, C++ allows storing either a character or integer value.

A	B
(a) Modulus	(2) Remainder of a division
(b) Separators	(3) Punctuators
(c) Stream extraction	(4) get from
(d) Lexical Units	(1) Tokens

Keywords are the reserved words which convey specific meaning to the C++ compiler. They are the essential elements to construct C++ programs. Most of the keywords are common to C, C++ and Java. Keywords are reserved and cannot be used as identifiers.

Algorithm	Program
Algorithm is for human readers to understand.	Program is for the computers to execute directly.
Knowledge of English is needed.	Knowledge of programming language is required.
Easy to understand.	It is difficult to understand.

1. Recursion is a method of solving problems that involves breaking a problem down into smaller and smaller sub problems until user gets in to a small problem that it can be solved trivially.
2. Usually recursion involves a function calling itself. While it may not seem like much on the surface, recursion allows us to write elegant solutions to problems that may otherwise be very difficult to program.

In iteration, the loop body is repeatedly executed as long as the loop condition is true. Each time the loop body is executed, the variables are updated.
However, there is also a property of the variables which remains unchanged by the execution of the loop body. This unchanging property is called the loop invariant.

The server distribution in Linux OS:
(i) Ubuntu Linux
(ii) Linux Mint
(iii) Arch Linux
(iv) Deepin
(v) Fedora
(vi) Debian
(vii) Centos

Open source refers to a program or software in which the source code is available in the web to all public, without any cost.

A Multi-user Operating system is a computer operating system (OS) that allows multiple users on different computers or terminals to access a single system with one OS on it.

A program counter (PC) is a CPU register in the computer processor which has the address of the next instruction to be executed from memory. It is a digital counter needed for faster execution of tasks as well as for tracking the current execution point.

It depends on
(a) Clock speed
(b) Instruction set
(c) Word size

Input Unit	Output Unit
An input device feeds information to a computer system for processing.	output device reproduces or displays the results of that processing.
Input devices only allow for input of data to a computer.	output devices only receive the output of data from another device.
It is a peripheral device used to provide data and control signals to an information processing system such as computer.	It is a unit which sends data from the computer to another device.
Eg. keyboard, mouse	Eg. printer, monitor

The control unit controls the flow of data between the CPU, memory I/O devices. It also controls the entire operations of a computer.

The Components of CPU are (a) Control Unit, (b) Arithmetic and Logic Unit (ALU), (c) Memory Unit.

Computer is an Electronic Machine, capable of performing basic operations like addition, multiplication, division etc. Computer accepts data as input, process it, produce output and stores it for future.
