C/C++ :: Using Strings To Find Out If A Name Is Repeated?

I have to write a code that will read in n amount of names and the names. Then it will tell me if the first name entered has been repeated or not.

This is my input:

5 Bush Reagan Lincoln Bush Obama

This is my output:

First name in list is not repeated.
First name in list is not repeated.
First name in list is repeated.
First name in list is not repeated.

I would like to just give one answer; if it is repeated then the output should simply be "First name in list is repeated."

If the answer is that it was not repeated, I would like the output to say once "First name in list is not repeated."

// lastnames.c

#include <stdlib.h>
#include <stdio.h>
int main(void) {
char FIRST[25];
