Define a class to represent a bank account. Include the following members:

Data members:

• Name of the depositor.
• Account number.
• Type of account.
• Balance amount in the account.
  Member functions:
• To assign initial values.
• To deposit an amount.
• To withdraw an amount after checking the balance.
• To display the name and balance.
  Write a main program to test the program.

Note: Here we will show output only for Three customers. But when you run this program you can see output for 10 customer.

Modify the class and the program of Exercise 5.12 such that the program would be able to add two vectors and display the resultant vector. (Note that we can pass objects as function arguments)

#include<iostream>
#include<iomanip>
#define size 8
using namespace std;
class vector
{
    float *p;
 
public:
    void creat_vector(void);
    void set_element(int i,float value);
    friend void add(vector v1,vector v2);
 
};
void vector::creat_vector(void)
{
    p=new float[size];
}
void vector::set_element(int i,float value)
{
    p[i]=value;
}
void add(vector v1,vector v2)
{
 
    float *sum;
    cout<<"sum["<<size<<"] = (";
    sum= new float[size];
 
    for(int i=0;i<size;i++)
    {
        sum[i]=v1.p[i]+v2.p[i];
        if(i==size-1)
             cout<<sum[i];
        else
            cout<<sum[i]<<" , ";
    }
    cout<<")"<<endl;
 
}
 
int main()
{
    vector x1,x2,x3;
    x1.creat_vector();
    x2.creat_vector();
    x3.creat_vector();
    cout<<" Enter "<<size<<" elements of FIRST vector : ";
    for(int i=0;i<size;i++)
    {
         float v;
         cin>>v;
         x1.set_element(i,v);
    }
 
    cout<<" Enter "<<size<<" elements of SECOND vector : ";
    for(i=0;i<size;i++)
    {
               float v;
         cin>>v;
         x2.set_element(i,v);
    }
    add(x1,x2);
 
    return 0;
}

Create two classes DM and DB which store the value of distances. DM stores distances in meters and centimeters and DB in feet and inches. Write a program that can read values for the class objects and add one object of DM with another object of DB.
Use a friend function to carry out the addition operation. The object that stores the results may be a DM object or DB object, depending on the units in which the results are required.
The display should be in the format of feet and inches or meters and centimeters depending on the object on display.

#include<iostream>
#define factor 0.3048
using namespace std;
class DB;
class DM
{
                    float d;
         public:
         void store(float x){d=x;}
         friend void sum(DM,DB);
         void show();
};
class DB
{
        float d1;
        public:
        void store(float y){d1=y;}
        friend void sum(DM,DB);
        void show();
};
 
void DM::show()
{
 
      cout<<"\n Distance = "<<d<<" meter or "<<d*100<<" centimeter\n";
}
 
void DB::show()
{
 
      cout<<"\n Distance = "<<d1<<" feet or "<<d1*12<<" inches \n";
}
void sum(DM m,DB b)
{
 
         float sum;
 
         sum=m.d+b.d1*factor;
         float f;
         f=sum/factor;
         DM m1;
         DB b1;
 
         m1.store(sum);
         b1.store(f);
 
       cout<<" press 1 to display result in meter\n"
          <<" press 2 to display result in feet \n"
          <<" What is your option ? : ";
          int test;
          cin>>test;
 
             if(test==1)
             m1.show();
             else if(test==2)
             b1.show();
 
 
}
 
 
int main()
{
     DM dm;
     DB db;
     dm.store(10.5);
     db.store(12.3);
    sum(dm,db);
     return 0;
