Write the definition for a class called complex that has floating point data members for storing real and imaginary parts. The class has the following member functions: void set(float, float) to set the specified value in object void disp() to display complex number object complex sum(complex) to sum two complex numbers & return complex number 1. Write the definitions for each of the above member functions. 2. Write main function to create three complex number objects. Set the value in two objects and call sum() to calculate sum and assign it in third object. Display all complex numbers.

 




#include <iostream>
using namespace std;
class complex
{
    int real, img;

public:
    void inputdata(int r, int i)
    {
        real = r;
        img = i;
    }

    void displaydata()
    {
        cout << real << " +i " << img;
    }

    friend complex sum(complex c1,complex c2)
    {
        complex temp;
        temp.real = c1.real + c2.real;
        temp.img = c1.img = c2.img;
        return (temp);
    }
};

int main()
{
    complex C1, C2, C3;
    C1.inputdata(5, 4);
    C2.inputdata(3, 7);
    C3 = sum(C1,C2);
    cout << "first complex number " << endl;
    C1.displaydata();
    cout << "second complex number " << endl;
    C2.displaydata();
    cout << "sum of two complex data :" << endl;
    C3.displaydata();
}

output :

5 +i 4second complex number 3 +i 7sum of two complex data : 8 +i 7

Define a class to represent a Bank Account. Include the following members: Data Members: i. Name of the depositor ii. Account number iii. Type of account iv. Balance amount in the account Member Functions: 1. To Input initial values 2. To deposit an amount 3. To withdraw an amount after checking the balance 4. To display name and balance Also write constructor for this class that takes four arguments. It should also handle type of account as savings by default

Assume that a bank maintains two kinds of accounts, are called as saving account and current account. The saving account provides compound interest and withdrawal facilities but no cheque book facility. The current account provides cheque book facility but no interest. Current account holders should also maintain a minimum balance and if the balance falls below the level, a service charge is imposed. Create a class account that stores customer name, account number and type of account. From this derive the classes cur_acct and sav_acct to make them more specific to their requirements. Include necessary member functions in order to achieve the following tasks: a.Include constructor for all the three classes. b.Accept deposit amount from the customer and update the balance. c.Display the balance. d.Compute and deposit interest. e.Permit withdrawal and update the balance. f. Check for minimum balance, impose penalty, necessary and update the balance.
