 Create a class “CString” to represent a string (Hint: Check Book Chapter Examples)   
    a) Overload the + operator to concatenate two strings.
    b) = = to compare 2 strings.

Answer:

#include "stdafx.h"

#include"iostream"

#include"conio.h"

#include"stdio.h"

#include"string.h"

 

using namespace std;

class CString

{

private:

       char s[20];

public:

       void input()

       {

       cout << "Enter String......" << endl;

       cin.getline(s, 20);

       }

       void output()

       {

              cout << "String is :"<<s << endl;

       }

       CString operator +(CString s0)

       {

              CString temp;

              strcpy(temp.s,s);

              strcat(temp.s, s0.s);

              return temp;

       }

       int operator ==(CString s3)

       {

              if (strlen(s3.s) == strlen(s))

              {

                     return 1;

              }

else

{

       return 0;

}

       }

};

 

int _tmain(int argc, _TCHAR* argv[])

{

       CString s1, s2,s3;

       cout << "Enter 1st String....." << endl;

       s1.input();

       cout << "1st String....." << endl;

       s1.output();

       cout << "Enter 2nd String....." << endl;

       s2.input();

       cout << "2nd String....." << endl;

       s2.output();

       cout << "3rd String....." << endl;

       cout << "s3=....." << endl;

       cout << "After Contatenation...." << endl;

       s3 = s1 + s2;

       cout << "s3 = ";

       s3.output();

       if (s1 == s2)

       {

              cout << "Both string are of same lenght " << endl;

       }

else

{

       cout << "Both strings are not of same lenght " << endl;

}

       _getch();

       return 0;

}


Create Two Objects m1 and m2 , Fill both objects matrices and display matrices then Find out m3=m1+m2 (use operator overloading).

Answer:

#include "stdafx.h"


#include"iostream"

#include"conio.h"

 

using namespace std;

class Matrix

{

private:

       int m[3][3];

public:

       void input()

       {

cout << "Enter values in matrix 3x3 :" <<endl;

       for (int i = 0; i < 3; i++)

              {

              for (int j = 0; j < 3; j++)

                     {

                           cin >> m[i][j];

                     }

              }

       }

       void output()

       {

       cout<<"The values in matrix 3x3 :"<<endl;

              for (int i = 0; i < 3; i++)

              {

                     for (int j = 0; j < 3; j++)

                     {

cout << "value in the matrix index [" << i << "][" << j << "]= " << m[i][j] << endl;

                     }

              }

       }

       void operator +(Matrix c)

       {

              Matrix temp;

              for (int i = 0; i < 3; i++)

              {

                     for (int j = 0; j < 3; j++)

                     {

              temp.m[i][j] = m[i][j] + c.m[i][j];

                     }

              }

       cout << "After Addition Matrix 3 is" << endl;

              for (int i = 0; i < 3; i++)

              {

                     for (int j = 0; j < 3; j++)

                     {

cout << "value in the matrix index [" << i << "]["

<< j << "]= " << temp.m[i][j] << endl;

 

                     }

              }

       }

       };

 

       int _tmain(int argc, _TCHAR* argv[])

       {

              Matrix a, b;

              cout << "Enter values in Matrix 1 " << endl;

              a.input();

              cout << "Enter values for Matrix 2 " << endl;

              b.input();

              cout << "Matrix 1 " << endl;


              a.output();

              cout << "Matrix 2 " << endl;

              b.output();

              a + b;

 

 

              _getch();

              return 0;

       }

  Pakistani journalists rally on the occasion of World Press Freedom Day in Karachi, Pakistan, May 3, 2018. The report, Press Freedom Barometer 2018, published ahead of Thursday’s observance of World Press Freedom Day, documents more than 150 violations against journalists and media groups in the country. The 16-page report’s violations include officially enforced censorship, written or verbal threats, killings, harassment, arrests, abductions, illegal confinements and physical assaults, conducted by state and nonstate actors and political and religious parties. “At least 157 cases of attacks and violations were documented in Pakistan between May 1, 2017, and April 1, 2018, across all four provinces, Islamabad and tribal areas. That’s an average of about 15 cases of violations a month,” the report noted. The executive director of Freedom Network, Iqbal Khattak, told VOA that despite a noticeable decline in overall terrorism in the country, journalism and journalists have remained v...

Write a program that will take 10 integer values from the user. a. If the entered value is Even then enqueue it into a queue at even index and if the entered value is Odd then enqueue it into a queue at odd index. (Note: Even index will start from 0 & odd will start from 1 ). b. Dequeue the values and display the sum of the even values and the sum of the odd values.

  Write down about at least three companies which were the victim of Computer or Internet crime. Apple Company:   Apple's iPhones enjoy a reputation for being ultra-secure and hard to hack, so most cybercriminals don't bother trying. However, you shouldn't think of your iPhone as a device that's totally safe from hackers. In February, a team of researchers at Google alerted Apple to vulnerabilities that persisted for two years and allowed hackers to embed malware on iPhones after people visited particular websites. What Happened? Even though researchers at Google found these issues months ago and reported them to Apple at that time, the team  only recently went public  with the discoveries. They revealed five so-called exploit chains that link security vulnerabilities together and allow hackers to get through each layer of the security protections built into an operating system. The exploit chains took advantage of 14 total security flaws that allowed cybercrim...
