Given two dates D1 and D2, write a program to count the number of Saturdays and Sundays from D1 to D2 (including D1 and D2).

The date in string format is like "8 Feb 2021".

sample input:

25 Jan 2021

14 Feb 2021

output:

Saturday: 3

Sunday: 3

The output should contain the sum and average of the numbers that appear in the string.

Note: Round the average value to two decimal places

sample input:

I am 25 years and 10 months old

output

37

17.5

In this Javascript coding program they had two test cases

We need all two test cases can be came when code was run. I want exact outputs for all two test cases

Star Children’s Academy has opened a movie theater in its own capacity to host movie afternoon once a week for every class (including all sections e.g. Class 1 has three sections Class1-A, Class1-B, Class1-C divided because of large strength in one class, so here one class means 3 sections’ students will be watching a movie together one week and then next week another class and its sections) covering the topics such as patriotism, kindness, love, self-awareness, animal care and protection, etc.   As a Visual Programmer, you are required to design and develop a Windows Form Application that facilitates the class teachers to reserve tickets on behalf of students for the movie. No student can reserve directly for himself.

Create a class string whose private data member is a character array of size 50. Create the constructor in default constructor assigns the null into the string. In parameter, constructor assigns the string which is passed by the user. Overload the '+'operator to add two string values. Overload the =' to compare to strings. Create its disp( function to display the string.
