Thread: Read in n, then n words, and check to see if first word is repeated.

Read in n, then n lastnames, and check to see if the first in the list is ever repeated again.

Here's what I have so far:

Code:

#include <stdio.h>
#include <stdlib.h>




int strcmp(char *w1, char *w2);


int main() {
    int j, n;
    char string1[30], string2[30];
    
    printf("Enter n, followed by n last names (each last name must be a single word): ");
    scanf("%d", &n);
    
    for(j=0; j<n; j++)
    {
        scanf("%s", string1);
    }




    if(strcmp(string1, string2))
        printf("First name in the list is repeated\n");
    else
        printf("First name in the list is not repeated\n");
        
    system("pause");
    return 0;
}

I see the problem is that it lies within n amount of string that I am not going through every string to compare to the first one.

How will do compare every string to the first one?


Current output:
3
alex
alex
alex
Not repeated
------------------
3
alex
ash
peter
Not repeated

correct input should be:
5 Reagan Bush Clinton Bush Obama
First name in list is not repeated.
------------------------------
4 Bush Clinton Bush Obama
First name in list is repeated.


Thanks
