SOLUTION

The peak voltage of the source is, $$\begin{gathered} Vm=\sqrt{Vrms} \\ =\sqrt{2}\times 220 V=331 V \\ The rms current is given by, \\ I=\frac{P}{Vrms} \\ =\frac{200 W}{220 V} \\ =0.86 A \end{gathered}$$

SOLUTION

The two nails are attracted to same pole of the bar magnet and hence, acquires same polarity. As a result, like poles of the nail repel each other.

SOLUTION

The capacitive reactance is, $\mathit{X}\mathit{c}\mathbf{=}\frac{\mathbf{1}}{\mathbf{2}\mathbf{\pi }\mathbf{\nu }\mathbf{C}}$ $\frac{1}{2\pi \times 50(20\times {10}^{-6})}\Omega$ $3.184 \Omega$ $$\begin{gathered} The rms current is, \\ I=\frac{V}{X_C} \\ =\frac{200 V}{31.84 \Omega }=6.281 A \\ The peak current is, \\ {i}_m=\sqrt{2}I=(1.41)(6.281 A) \\ =8.856 A \end{gathered}$$

SOLUTION

I, instantaneous value of current is, $I=I_0\sin \omega t$ and rms value of current is ${\mathrm{I}}_{\mathrm{rsm}}=\frac{{\mathrm{I}}_0}{\sqrt{2}}$ Here, I instantaneous value of current is, $$\begin{gathered} \mathrm{I}=\left(\frac{1}{\sqrt{2}}\right)\sin \left(\mathrm{\omega t}+\mathrm{\Phi }\right) \\ \mathrm{Thus}, {\mathrm{I}}_0=\frac{1}{\sqrt{2}} \\ {\mathrm{I}}_{\mathrm{rms}}=\frac{{\mathrm{I}}_0}{\sqrt{2}} \\ =\frac{{\displaystyle \raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$\sqrt{2}$}\right.}}{\sqrt{2}} \\ =\frac{1}{2} \end{gathered}$$  

SOLUTION

Every statement in C++ terminates with a semicolon (;). It indicates the end of the line.

SOLUTION

Every C++ program has a function named main(). In a program execution is always starts from main() function.

SOLUTION

Procedural programming aims at procedures. It is a list of instructions telling a computer, step by step, what to do, usually having a linear order of execution from the first statement to the second.

SOLUTION

:: is a scope resolution operator, used to access global value of i.

SOLUTION

Identifiers can start with _, but not digits. Identifier is an arbitrarily long sequence of letters and digits. Upper and lower case are different. Single character constants have type int.

SOLUTION

A real constant in exponent form has two parts: a mantissa and an exponent. The mantissa must be either an integer or a proper real constant. The mantissa is followed by a letter E or e and the exponent. The exponent must be an integer.

SOLUTION

The property by which one class (subclass) inherits the properties of super class is known as inheritance. This is a relationship between subclass (derived class) and superclass (base class).

SOLUTION

A string literal is a sequence of characters surrounded by double quotes.

SOLUTION

A temporary instance of a class means an anonymous object (having no name) of the same class.

SOLUTION

{} are used for more than one statement in the block of a for loop. When there is a single statement then () are used.
For example:
for (i=0; i <=10; i++).
It will execute the code within for loop for 10 times.

SOLUTION

An if statement tests a particular condiiton; if the condition evaluates to true, a course-of-action is followed i.e., a statement or set-of-statements is executed. Otherwise, the course-of-action is ignored. It will always print hello because we have used assignment operator here instead of comparison operator.

SOLUTION

Relational operators determine the relation among different operands. It compare numbers and characters and does not work with strings. If comparison is true, the relational expression results into value 1 or 0.

SOLUTION

A function that calls itself directly or indirectly is referred to as recursive  function.

SOLUTION

The three expressions are the initialization expression, test expression and the increment/decrement (reinitialization) expression.

SOLUTION

puts() belongs to stdio.h header file and strcmp() belongs to string.h header file.

SOLUTION

The two types of functions available in C++ are:

Implicit and Explicit functions.

SOLUTION

Modular programming is the breaking down of the program into smaller sub tasks, which in turn may be broken down again so that the lowest-level functions are as simple as possible.

SOLUTION

The output of the above code is 2 4 2.

SOLUTION

The basic features of object oriented programming are data abstraction, data encapsulation, inheritance, and polymorphism.

SOLUTION

The header files needed for the successful compilation of the above code are: string.h and stdio.h.

SOLUTION

The key to function overloading is a function's argument list which is also known as the function signature.

SOLUTION

Data abstraction is focussing on important features leaving behind the unessential part.

SOLUTION

Data hiding is a concept related to data abstraction.

SOLUTION

Through encapsulation, an inteface is made available to the world through which users can use the class.

SOLUTION

Procedural programming is susceptible to design changes, which leads to many modifications in the code. This results in increased time and cost overheads at times.

SOLUTION

Paradigm refers to a way of doing things. A programming paradigm gives you an idea how problems are generally analyzed and solved in a particular programming language.

SOLUTION

Public data is accessible even outside the class.

SOLUTION

Private data is accessible within a class only. Any data which is declared private inside a class is not accessible from outside the class. A function which is not a member or an external class can never access such private data.

SOLUTION

A class is a way to bind the data describing an entity and its associated functions together.

SOLUTION

The object-based programming is a subset of object-oriented programming. It implements some of the features of object oriented programming but it does not implement inheritance and thereby polymorphism.

SOLUTION

Object oriented programming offers all the features of object based programming and overcomes its limitations by implementing inheritance.

SOLUTION

Dynamic binding is the process of binding in which compiler binds the indentifiers with its addresses at run-time. It is also known as late binding.

SOLUTION

When a system determines how to implement an action at compile time, is called early binding or static binding.

SOLUTION

The signature of a function is roughly equivalent to its prototype definition.

SOLUTION

A virtual function is one whose behaviour can be overriden within an inheriting class by a function with the same signature.

SOLUTION

Function overloading is the feature of OOP in which more than one function could have some name with different argument list.

SOLUTION

Polymorphism is the attribute that allows one interface to be used with different situations.

SOLUTION

Inheritance is implemented in C++ by specifying the name of the (base) class from which the class being defined(the derived class) has to inherit from.

SOLUTION

Concrete class is the derived class that implements all the missing functionalities which are not implemented in the base class or abstract class.

SOLUTION

There are two kind of members in a class: data members and member functions. Data members are exactly like the variables in a structure and member functions act on data members in the class.

SOLUTION

The output is as follows -

          2023

          1023

SOLUTION

C++ provides four storage class modifiers : auto, register, static and extern. The auto specifier tells that this variable will be created when the function is called and it will be destroyed when the function returns. 

SOLUTION

Header files, also called include files, provide function prototype declarations for library functions.

SOLUTION

In call by value method, the called function creates its own copies of original values sent to it. Any changes, that are made, occur on the function's copy of values and are not reflected back to the calling function.

Whereas, in call by reference method, the called function accesses and works with the original values using their references. Any changes, that occur, take place on the original values and are reflected back to the calling code.

SOLUTION

(i)  The # include compiler directive includes desired header files in our program.
(ii)  It supports modularity, i.e., a bigger program can be decomposed in terms of header files and later included as a pre-processor directive.

SOLUTION

(i)  Whenever a C++ program is executed, only the main() is executed. The execution of a program starts and ends at main().

(ii) The main() is the driver function of the program. If it is not included in the program, no execution can take place.

SOLUTION

The output is:

               5 9

               9 7

               7 7

               7 9
