I did encounter and solve this problem with Java but I cannot seem to implement the use of structures in solving this problem. Help is appreciated, thank you. Using the concept of structures, write a program to assign passenger seats in an airplane. Assume a small airplane with seats numbered as follows: 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D The program should display the seat pattern, marking with an ‘X’ the seats already assigned. For example, after seats 1A, 2B, and 4C are taken, the display should look like: 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D Seats are assigned by specifying a number and a letter. If the user types in a seat that is already assigned, the program should say that the seat is occupied and ask for another choice. The program should run until all seats are…
- In what ways may an enumeration type be preferable to a collection of named constants? In what ways may a subrange type be preferable to its base type? In what ways may a string be preferable to an array of characters?Please help in C++ I can only make changes in the sentences.cpp file.C++ Programming Problem: After Elon Musk decided to make a new business idea. He found a social network called "Friends.com". It has currently N registered users. Likewise in any social network many users can be friends. Elon Musk wants the world to be as super connected as possible, so he has this new way to suggest friendship to some pairs of users. He suggests user u to have a friendship with user v if they are not friends yet and there is a user w who is friends of both of them. Note that u, v and w are different users. Elon Musk is too busy with SpaceX these days, so he hired you to develop a C++ program to count out how many friendship suggestions he has to send over his social network "Friends.com".
