Header files

A file with an extension that has some predefined declarations and definitions is called a header file. Every computer program imports a set of header files to perform common tasks such as getting input, displaying output, and so forth. Every language has different header files (such as C, JAVA, Python, and C++). In this article, header files are explained mainly in the context of the C/C++ language.

Question

We have if statement, and we want to use an exception to check the right input with if-else and how it works

Task:
Write a program that converts dates from numerical month/day/year format to normal “month day,
year" format (for example, 12/25/2021 corresponds to December 25, 2021). You will define three
exception classes, one called MonthException, another called DayException, and a third
called YearException. If the user enters anything other than a legal month number (integers from
1 to 12), your program will throw and catch a MonthException and ask the user to reenter the
month. Similarly, if the user enters anything other than a valid day number (integers from 1 to either
28, 29, 30, or 31, depending on the month and year), then your program will throw and catch a
DayException and ask the user to reenter the day. If the user enters a year that is not in the range
1000 to 3000 (inclusive), then your program will throw and catch a YearException and ask the
user to reenter the year. (There is nothing very special about the numbers 1000 and 3000 other than
giving a good range of likely dates.)
In the main program, you will ask user to enter the date in MM/DD/YYYY format and then print
the formatted date if user enters the valid date.
[Hint: Use StringTokenizer class to parse the date input by user. Read some stuff about
StringTokenizer here https://docs.oracle.com/javase/7/docs/api/java/util/StringTokenizer.html]

Java
For Java Write code for an if-else block that checks separates integers into the following categories: An integer less than 0, An integer greater than 0 and less than or equal to 10, An integer greater than 10 that is even, and an integer greater than 10 that is odd. Have each category print out a different statement. What are some ways you can make your code more efficient when using if-else blocks?
C++ Accept a package weight of zero; we'll ship it! If the user enters a weight that is less than zero, set it at zero instead. Do not display an error. If the distance is less than 500 miles, we'll ship that as well but we will charge for a full 500 miles. But if the distance is less than zero, set the distance to zero (which is really 500) and charge the user accordingly. This means that we will in fact ship your package less than ten miles (which differs from what the textbook says) but we will charge you quite a bit for that. We charge by the mile, so accept distances that are not multiples of 500 (e.g. 650 miles) and compute the fee accordingly (more than the cost for 500 miles, but less than for 1000). Fractions of miles are allowed so bring that input in as a double. For your screen shot, enter a package weight of 12.5 kg to be shipped 1310.5 miles. As always for money, the shipping charge should show exactly two digits after the decimal point. For parameters that are out of…
Can you write this in C++?? Assignment 8 B: Hit Boxes (Part 2). Back in Assignment 2 (so long ago!) we created a simple program to determine what a hit box would be. Now we’re going to use that information to determine if two characters would collide based on those hit boxes.You will create a Player class that takes in the following private attributes (as integers) when creates Width Height X position Y position In addition to Getter methods for all four attributes, the Player class should also have the following methods:  MoveHorizontal(int x_delta)◦ Takes in either a negative integer (for moving left) or a positive integer (for moving right). It should update the X position of the Player object MoveVertical(int y_delta)◦ Takes in either a negative integer (for moving down) or a positive integer (for moving up). It should update the Y position of the Player object DidTheyCollide(Player otherPlayer)◦ Takes in another player object, and returns true if they collided with each…
