Student List
A teacher wants to list all her students’ full names,
considering only for the two students at the front and the end of the list that must be in alphabetical order
. That meant the student at the top and at the end of the list will be set alphabetically according to their full name.
Write a C++ program that can help her with the issue. The list of names could be either read in from an external text file or entered from the keyboard, one full name at a time.
Once all the names have been read in, the program reports which name should be at the top of the list, and which name should be at the end of the list, in alphabetical order of their names. Also, the list of names must be displayed on the screen, together with the original order that their names were entered, for the teacher to check back of her record.
Assume that no two students have the same name.
Using an array, (or C++ standard library vector, set, list), is not allowed and will have no credit, absolutely.
Lastly, allow your program to run continuously as often as the user wishes (for another set of names). Before ending the program, your name as the programmer must be displayed.
Input validation: the number of students must be
in the range of 5 to 45, inclusively
.
Hint: Why is array not allowed? Because there is no need for sorting alphabetically all the names. (
considering only for the two students at the front and the end of the list that must be in alphabetical order
.) So, use an external file as a temporary place to store all the names entered, and use string comparison with relational operators, (<,>) to check for their alphabetical order.
