Question

C++ Project.

For this project, you will create a class for an elementary school that will allow a teacher to enter each student's seating assignment. Occasionally, the teacher may need to switch the seating assignment of a student. If there is a seat available, the student is moved. If all of the seats are already assigned, the teacher will have two students trade seats.      

Minimum Requirements:

Create a class that has a string array of size 20 as a private data member. You cannot use a vector for this assignment (5 points).

Include a function to add students to the seating chart array (5 points). Position 0 of the array represents the seat closest to the teacher's desk. The array index will represent each seat number for the seating assignments.

Include a function that will accept a student name and a target seat. This function should find the students name in the array and move the student's name from his or her original seat to the target seat. If the target seat is empty, move the student's name to the target seat. If the target seat is not empty, swap the names of the students so they trade seating assignments. (5 points).
