 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;

       }

  Write a C++ program to implement a suitable data structures (using array) of marble plates. Your program should cover the following scenario, Suppose a waiter in a hotel is collecting plates from different tables and giving to dish washer. Dish washer is washing plates and throwing them into rack of plates. Some plates hit others very hard to break other (one above it) and/or itself. You need to develop an application that will find how many plates are broken and plates from which tables are broken. You will identify plates with unique numeric identity number. Every 5 th plate thrown into rack will break itself and one plate below it while every 7th plate will only break itself. Answer: #include "stdafx.h" #include "iostream" #include "conio.h" using namespace std; class Dishwasher { private :       int data[10];       int top;       int bottom;       int size; public :      Dishwasher() { ...

  How can we make our presentation attractive?  Use all the important techniques regarding oral presentation skills and prepare the material for a speech on “awareness raising for fighting against COVID-19 pandemic”.   To make our presentation attractive user the following tips: Vary the speed & tone of your voice to keep your voice interesting to listen to. Project your voice to be easily heard and to show confidence in what you are saying. Pause to gain attention and allow students the opportunity to digest information. Maintain eye contact with the audience and stand up straight to project confidence. Smile to communicate that you value what you are saying. Use movement to convey energy but avoid excessive gesturing because it can divert attention from your message. Project excitement and energy to capture your audience’s attention.  Slide presentations are useful for organizing a variety ...
