Strings: Finding if the first word is repeated using strcmp - c++

Question

I have an assignment where I have to type in the amount of names I want to compare. Then I have to see if the first name printed is repeated in the names I printed. For example if I put in 5 Reagan, Bush, Reagan, Bush, Clinton it will print out "The first name was repeated" but if I put in Davis for either of the Reagans it would say no. I've attempted a for loop and if statements but I can't seem to find the correct output. I am using Dev C++ and here is what I have so far.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main () {
char curname[30], firstname[30];
int num, i, freq = 1;
printf("How many names do you want to enter?\n");
scanf("%d", &num);
printf("What is the first name?");
scanf("%s", firstname);
printf("Enter each of their names.\n");
for (i=0; i<num; i++) {
scanf("%s", curname);
if (i==0) {
strcmp(curname, firstname) != 0;
printf("The first name in the list was repeated.\n");
}
else if (strcmp(curname, firstname) == 1)
printf("The first name in the list was not repeated.\n");
}
system("pause");
return 0;
}

Answer 1

You need to do only one comparison and print your message based on the result of that comparison.
if (strcmp(curname, firstname) == 0 ) {
printf("The first name in the list was repeated.\n");
}
else {
printf("The first name in the list was not repeated.\n");
}
Its always worthwhile to be very clear on what the return value of any function call is, in this case strcmp.

Answer 2

you have to compare names, strcmpi is more appropriate (case insensitive comparison)
if (strcmpi(curname, firstname)==0)
printf("The first name in the list was repeated.\n");
else
printf("The first name in the list was not repeated.\n");

Answer 3

strcmp return value may be greater 0 or less then 0, so:
strcmp(curname, firstname) == 1
change to:
strcmp(curname, firstname) != 0
others: You did not record the names into a list, so you can not find the name if or not repeated.

Answer 4

So I have edited my program based on the suggestions. Here is what I have now. It will only give me the correct output if the name is entered as the last value. Thank you so much!! :)
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main () {
char curname[30], firstname[30];
int num, i, freq = 1;
// Read in the number of students.
printf("How many names do you want to enter?\n");
scanf("%d", &num);
printf("What is the first name?\n");
scanf("%s", firstname);
printf("Enter each of their names.\n");
for (i=0; i<num; i++)
// Read the current name.
scanf("%s", curname);
// Always update the best seen for the first name.
if (strcmp(firstname, curname)== 0) {
printf("The first name in the list was repeated.\n"); }
else
printf("The first name in the list was not repeated.\n");
system("pause");
return 0;
}
