C++ car parking management system

This is C++ car parking management system. The statement of car parking management system is:

There are three floors in a building and every floor has capacity of ten cars to park.one floor is for Civic, one for Accord and one for City. Whenever a car system should ask either it is civic, Accord or City and it should be park on its floor if there exists room.

#include<iostream>

using namespace std;

enum{M=10};

class park

{private:

int capacity[M];int front,rear,g;

public:

            park()

            {front=rear=-1;g=0;}

            void inpark()

            {if(rear==M-1)

How to make copy constructor in C++,with code example

In copy constructor, we copy a constructor to another object. When we have to make a constructor with same values of attributes which another constructor have, then we use copy constructor technique.

I give an example code in C++ to understand copy constructor concept.

#include<iostream>

using namespace std;

class distancee

{ private:

int feet;

How to concatenate two or more strings of different objects in C++ with example code

In concatenation, we concatenate two or more strings together. Concatenation syntax in C++ is:

strcat(str1,str2);

Here:

str1 and str2 are two strings which are concatenated and the result is stored in left side’s string which is in above case is str1,so here result will be stored in str1.

Example Code:

In this example code strings which belong to two different objects are concatenated.

#include<iostream>

using namespace std;

#include<string>

Toll Plaza management system

                                                     This project is on toll plaza management, whenever any vehicle will pass the toll plaza, it has to pay tax. This system tell us that there are how many vehicles which have paid and how many such vehicles which don’t paid toll plaza tax.

#include<iostream>

using namespace std;

char a;

char b;

char c;

class sir

{

private:  

                unsigned int cars;

                unsigned int amount;

public:

How to pass objects as parameters in the function with code example

We can pass objects as parameter in the functions.to use objects as parameter, we just pass the object’s name as in the case of array.

Let a1 and a2 are two objects and “add” is a function name then we will pass these objects as parameters as

add(a1,a2);

When we make function to pass objects as parameter then the data types of function attribute must be the name of that class in which we are making that function.

I explain this concepts using a complete code example

This code add, subtract and multiply two objects values

#include<iostream>

#include<math.h>

using namespace std;

class complex

{

private:

            float real;

            float imaginary;

public:

            complex():real(0),imaginary(0)

            {}

complex(float re,float im):real(re),imaginary(im)

{}

void add(complex a,complex b)

{float z;

            float x,y,k;

            z=a.real+b.real;

            x=-(a.imaginary);

            y=-(b.imaginary);

            k=sqrt(x)+sqrt(y);

            cout<<endl<<"addition is  "<<z<<"+"<<k<<"i"<<endl;

}

void subtruct(complex s,complex w)

{float z;

            float x,y,k;

            z=s.real-w.real;

            x=-(s.imaginary);

            y=-(w.imaginary);

            k=sqrt(x)-sqrt(y);

            cout<<endl<<"subtrucrtion is  this"<<endl<<z;

if(k>=0)

{cout<<"+"<<k<<"i"<<endl;}

else

{cout<<"-"<<k<<"i"<<endl;}}

void product(complex f1,complex f2)

{float z;

            float x,y,k,o,t,r1,r2;

            z=f1.real*f2.real;

            x=-(f1.imaginary);

                        y=-(f2.imaginary);

                        k=(f1.real)*(sqrt(y));

                        o=(f2.real)*(f1.imaginary);

                        t=x*y;

                        r1=z+t;

                        r2=k+o;

                        cout<<endl<<"production is this   "<<r1;

                        if(r2>=0)

                        {

                                    cout<<"+"<<r2<<endl;}

                        else

                        {cout<<"-"<<r2<<endl;}}

void getdata()

{

cout<<"enter real and imaginary  ";

            cin>>real>>imaginary;}

};

void main()

{

             complex i(12.2,-25.3);

            complex e1,e2,e3,e4;

            e1.getdata();

            e2.add(i,e1);

            e3.subtruct(i,e1);

            e4.product(i,e1);

             system("pause");}

Here:

void add(complex a,complex b);

void subtruct(complex s,complex w);

void product(complex f1,complex f2);

These are the function declaration method to use objects as parameters and here complex is the name of class in which these functions are made.

And

            e2.add(i,e1);

            e3.subtruct(i,e1);

            e4.product(i,e1);

Here functions are called in which objects are passed as parameters;

Here i, e1, e2 and e3 are objects names.
