(Geometry: distance of two points)
Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them.
The formula for computing the distance is:
Square root of ((x2 - x1) squared + (y2 - y1) squared)
Note that you can use pow(a, 0.5) to compute square root of a.
Sample Run
Enter x1 and y1: 1.5 -3.4
Enter x2 and y2: 4 5
The distance between the two points is 8.764131445842194
(Find future dates) Write a program that prompts the user to enter an
integer for today’s day of the week (Sunday is 0, Monday is 1, …, and Saturday is
6). Also prompt the user to enter the number of days after today for a future day
and display the future day of the week.
(Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input.
Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number
because 1+2+3+4 = 10 and 1 +0 = 1, while 1235 is not (1 +2+ 3 +5 = 11 and 1 +1 = 2). Write a program that prints out
the first N magic numbers, seven on each line.
Here is the sample output:

You are required to use the following function prototype:
bool isMagic(int value); // Returns true if value is a magic number
The outline of this function will be as follows:
Step 1: Calculate the sum of digits of value
Step 2: Repeat Step 1 until we get a single digit
Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise not
