Validate IP Address. Create a program and reads an IP address and determines whether it is syntactically correct or not. Assume the format of the IP address is 999.999.999.999 where 999 represents a number between 0 and 255. Use the `split function to access th

Assume a given email is valid. Write a program which extracts the username and domain from a valid email address using string::find and string::substr methods. Sample output: Type your valid email: eyildirim@qcc.cuny.edu Username: eyildirim Domain: qcc.cuny.edu   C++ #include <iostream>#include <string>using namespace std

The International Standard Book Number (ISBN) is a number that uniquely identifies a book. Publishers can buy or receive ISBNs from the International ISBN Agency. There are two types of ISBNs: ISBN-13 and ISBN-10, which are 10- and 13-digits long, respectively.ISBN-10 has a pattern, where the last digit can be found using the first 9. Additionally, ISBN-10 can also be used to calculate its ISBN-13 equivalent (and vice versa). Write two functions in ISBN.java. The main method is implemented for you so you can test your functions. Instructions on how to run this file to make use of the test.txt file are detailed below. calculateISBN10(int[] isbn) computes the last digit of the ISBN-10 number. The first 9 of the 10 digits of the ISBN will be passed to the function as the parameter isbn integer array of size 10. The last integer in the array will be -1. Your job is to calculate the last digit (called the check digit), and update the last index of the isbn array with the computed…

I'm running a 5-star restaurant and I can only have the best items on my menu. My menu offers 6 items, each represented by a number from 1-6. If an item on my menu does not sell or does not sell that much compared to others, I must act and replace it with something that sells! Identify which dishes do not sell. If every dish sells, print the set of dishes that were ordered least. Input: A single line containing the dish number that were ordered. Treat as one number. INPUT: 156356231 Output: The list of dishes not ordered in numerical order. If every dish sells, print the set of dishes that were ordered least. Separate each number with a new line. OUTPUT: 4

Q2: Secret Courses Dan's recently announced that he's teaching n top-secret courses next semester. Instead of enrolling in them through ACORN, students need to email Dan to express their interests. These courses are numbered from 1 to n in some arbitrary order. In particular, if a student named s is interested in taking a course c, they need to send an email to Dan containing the message c s. Note that if a student is interested in taking multiple courses, they need to send multiple emails, one per course. Upon receiving a message c s, Dan looks at the list of students already enrolled in course c. If there's already a student on the list whose name is too similar to s, Dan assumes s is the same student and ignores the message. Otherwise, he enrolls s in the course. Dan considers two names too similar if and only if they have the same length and differ in at most one letter (note that "a" and "A" are considered the same letter). For example, "Josh" and "Josh" are too similar. "Sam" and…
