The kids Ram and Anandh are using magic numbers. For example, Ram magic number is 4 and Anandh magic number is 6. The kids exchange their magic number and display the Ram magic number is 6 and Anandh magic number is 4. Implement the above logic using function. [Note: Use call by address]

Write a function Unique_digit and the function to find the count of unique digits in a given number N. The number will be passed to the program as the input of type int.

Assumption: The input number will be a positive integer number>=1 and <= 25000.

For e.g.

If the given number is 292, the program should print 2 because there are only 2 unique digits "2" and "9" int this number.

A program prompts a user to enter two numbers, obtains the two numbers from the user, calculates and prints the sum, product, difference, and quotient of the two numbers.

Write a program that asks the user for a number between 10 and 30 inclusive and will validate, that is test, the input. It should repeatedly ask the user for this number until the input is within the valid range.

Develop a C++ program to display the string in left and right justifications. Specify the width as 20 and consider the special character to be filled as ‘&’.

Write an inline function sum() with four parameters that calculates the

arguments

provided and returns their sum.

Parameters: Four variables of type long.

Returns: The sum of type long.

Use the default argument 0 to declare the last two parameter.

Develop a C++ program to find the given number is positive or negative using user-defined manipulators.

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

Create the class Circle with attribute radius to find the area of circle. Assign the values for data member using copy constructor and display the result. Finally free the resources of data objects using destructor member function. (Note: Area of circle = 3.14 * radius * radius)
