Inheritance is the process by which objects can acquire the properties of objects of other class.

A structure is a collection of variable which can be same or different types.

Example:

struct student

{

int regno;

char name[20];

char class[5];

char combination[4];

float fees;

} st1,st2,st3;

The different types of type conversion are

Implicit conversion and 

Explicit conversion.

Declaration syntax of two dimensional array.

Syntax:

<data-type> <array-name> [<rowsize>] [<columnsize>];

Example: int marks[5][5];

Operating activities and Investing Activities are two activities of Cash Flow Statement.

The two types of functions are in-built functions and user defined functions. The functions are also classified as function with no argument and no return value, function with argument and no return value, function with argument and return value and recursive function.

Excess of Current assets over Current Liabilities is called working Capital. i.e. Current Assets – Current Liabilities

The word art is application of text that can be presented as graphical rich text. The graphical text can be filled with effects, shown upside down, wavy texts, text in arch shape etc.,

A statement of Assets and Liabilities prepared at the end of accounting year to depict the financial position of the business is called position statement.

Impact printers forms characters or images by striking a mechanism such as a print hammer or wheel against an inked ribbon, leaving an image on paper.

For example, dot matrix printer.

It may be affected by window dressing.

#include <iostream>

//main() is where program execution begins.

int main()

{

cout <<"Hello world";// prints Hello world

return o;

}

The various parts of the above program:

1. headers, which contain information that is either necessary or useful to program. For this program, the header is needed. 

2. The next line // main() is where program execution begins, is a single-line comment available in C++. Single-line comments begin with // and stop at the end of the line.

3. The line int main() is the main function where program execution begins.

4. The pair of { } indicates the body of the main function.

5. The next line cout<< “This is my first C++ program.”; causes the message “This is my first C++ program” to be displayed on the screen.

6. The next line return 0; terminates main( )function and causes it to return the value 0 to the calling process.

\(tan(\frac\pi4 + \theta) + tan(\frac\pi4 - \theta) = x\)

⇒ \(\cfrac{tan\frac\pi4 + tan\theta}{1- tan\frac\pi4 \,tan\theta} + \cfrac{tan\frac\pi4 - tan\theta}{1 + tan\frac\pi4\,tan\theta} = x\)

⇒ \(\frac{1 + tan\theta}{1 - tan\theta} + \frac{1-tan\theta}{1 + tan\theta} =x\)

⇒ \(\frac{(1 + tan\theta)^2 + (1 - tan\theta)^2}{(1 - tan\theta)(1 + tan\theta)} = x\)

⇒ \(x = \frac{2(1 + tan^2\theta)}{1 - tan^2\theta}\)     ......(1)

Now, \(tan^2(\frac\pi4 + \theta) + tan^2(\frac\pi4 - \theta)\)

\(= \left(\frac{1 + tan\theta}{1 - tan\theta}\right)^2 + \left(\frac{1 - tan\theta}{1 + tan\theta}\right)^2\)

\(= \frac{(1 + tan\theta)^4 + (1 - \tan\theta)^4}{(1 - tan\theta)^2(1 + tan\theta)^2}\)

\(= \frac{2(1 + 6tan^2\theta + tan^4\theta)}{(1 - tan^2\theta)^2}\)    ......(2)

From (1), 

\(x^2 -2 = \frac{4(1 + tan^2\theta)^2}{(1 - tan^2\theta)^2} - 2 \)

\(= \frac{4(1 +2tan^2\theta + tan^4\theta)}{(1 - tan^2\theta)^2} - 2\)

\(= \frac{4(1 + 2tan^2\theta + tan^4\theta) - 2(1 - 2tan^2\theta + tan^4\theta)}{(1 -tan^2\theta)^2}\)

\(= \frac{2 + 12tan^2\theta + 2tan^4\theta}{(1 - tan^2\theta )^2}\)

\(= \frac{2(1 + 6tan^2\theta + tan^4\theta)}{( 1 - tan^2\theta )^2}\)

\(= tan^2(\frac\pi4 + \theta) + tan^2(\frac\pi4 -\theta)\)    (From(2))

Hence proved.

The three Advantages of flowchart are:

1. It is a means of communication and easy to understand

2. Easy to convert into a program code.

3. Independent of programming language. i.e., a flowchart can be used to write programs using different programming languages.

4. Easy to test the program for errors and easy removal of such errors

Maximum number of Partners in a partnership firm are 50.

The language translators translate user written high level language programs to equivalent machine or assembly language program. There are three different types of translators. They are compiler, interpreter and assembler.

1. Compiler:

It is a computer language translator that checks the entire userwritten program and if error-free, produces a complete program in machine language.

2. Interpreter:

The Interpreter is a language translator which translates high level programs one statement at a time and, if error free, executes.
