How to program a button to calculate pricing and adding to a list box:

my teacher was very vague on how to do this, we are using else/if statements to do this, my question is how would I go about adding information using radio buttons and pricing them and then adding them to the list box using Else/if statements

Define a class Fixed_Deposit with the following specifications, the program uses three overloaded constructors. The parameter values to these constructors are provided at run time. The user can provide input in the following forms.

   1. Amount, period and interest in decimal form.

   2. Amount, period and interest in percent form.

   3. Amount and period.

PRIVATE DATA MEMBERS:

P_Amount long int type Years integer type Rate float type R_value float type

PUBLIC MEMBER FUNCTIONS:

Fixed_Deposit() Null constructor

Fixed_Deposit(p, y, r=0.12) Parameterized constructor with default arguments to accept values for P_Amount, Years and Rate(in Percent e.g., 0.12, 0.09)

Fixed_Deposit(p, y, r) Parameterized constructor with default arguments to accept values for P_Amount, Years and Rate(in Decimal e.g, 12%, 8%)

display() Function to display the P_Amount and R_Value

~Fixed_Deposit() Destructor to destroy the data objects

 Develop a C++ program to calculate sum of square root from 1 to n numbers using recursive functions.

Declare the base class circle with attribute radius. Assign the values in default constructor, member functions are getdata() to get input values for data members, develop member function area() to find the area of circle and display() to print the area of circle using multilevel inheritance.

Declare the class Employee, consisting of data members are emp_number and emp_age. Invoke a null constructor Employee() when an object is created, the parameterized constructor Employee(en, eg) to assign values for the data members, show() member function is used to display the information of Employee. Finally free the resources of data objects using destructor member function.

Declare the class Employee, consisting of data members are emp_number, emp_name, department, salary and net_salary. The member functions are GetEmpDetails() to accept information for an employee, Calculate_DA() to calculate DA=20% of salary and display() to display the information of a employee.

Write a function second_last_digit in C++ and call function that print the second last digit of the given number. The second last digit is being referred to the digit in the tens place in the given number. 

For example, if the given number is 197, the second last digit is 9.

Note 1 - The second last digit should be returned as a positive number. i.e. if the given number is -197, the second last digit is 9.

Note 2 - If the given number is a single-digit number, then the second last digit does not exist. In such cases, the program should print -1. i.e. if the given number is 5, the second last digit should be print as -1.

Implement a C++ program to define function named as ext, to extract the digits that located at even and odd position of five digit number and show the result.

Rohit goes to the market to buy Apples. After surveying the market he has to decide the quantity of apples he is supposed to buy.

Following are the requirements, which helps Rohit to decide how many kgs he can buy.

1. Capture the price of apple.

2. If the price of Apples is 100, the buy 5 kgs of apple.

3. If the price is an less than 100 but more than 80 then buy 8kgs of Apple.

4. If the price is less than 80 buy 10kgs of Apple.

5. Now calculate the cost price [Cost = Quantity * Price]

6. Display the cost at which Rohit has bought the Apples.

Develop a C++ program to get the temperature and print the following status according to the given temperature by using else if ladder statement. 

       1. T<=0            "Its very very cold"

           2. 0 < T <=10        "Its cold"

           3. 10 < T < =20      "Its cool out"

           4. 20 < T < =30     "Its warm"

           5. T>30            "Its hot
