How would I order the names alphabetically?

You're supposed to be able to enter the amount of classmates (in the first line) and then write their names (e.g. 4 and Alex, Bones, Charles). Everything works out except for the last part. It doesn't print out the names in an alphabetic order. E.g. if you type in "Bones" in the last line as an answer, the program is supposed to print out Bones, Charles. Because it will start from "B" and go down in an alphabetic order, leaving behind the names with a letter that comes before the one that was written in the given name.

You ask for 4 students ... and then enter 3?

Not convinced.

Last part of what?

Well, it's hoped that you entered the names in alphabetical order in the first place; otherwise, you will have to sort them (std::sort).



vet[i] isn't a c-string, so don't use strcmp.

vet[i] is only one array element - so it's not going to print out everything after it as well.
Perhaps:

	std::sort(vet, vet + n);

	for (size_t i = 0, fnd = 0; i < n && i < N; ++i) {

		if (fnd)
			std::cout << vet[i] << '\n';
	}
}



Enter the amount of scholars: 3
Enter the name of the scholar: 1: bones
Enter the name of the scholar: 2: alex
Enter the name of the scholar: 3: charles

Enter the name of the scholar to start from: bones

Alphabetically ordered names:
bones
charles
