Loop doesn't work correctly (strings)

Question

I'm writing a program that will sort words you input alphabetically, but I found it impossible to progress because the loop doesn't work as intended.

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

int main()
{
char string[50][50];
int i, n;

printf("Insert the number of strings: ");
scanf("%d ", &n);

for(i=0; i < n; i++)
    {
        printf("Insert %d. string: ", i+1);
        fgets(string[i],50,stdin);
    }

return 0;
}

I tried using gets() and tried to use fgets(), but the result is the same. It prints:

Insert 1. string: Insert 2. string:

Then you can insert strings, but 1 less than specified.

Remove semicolon after `for (i=0; i < n; i++);` Voting to close as a typo. — Sergey Kalinichenko, Mar 26 '17 at 11:42
Okay, I removed it but it still doesn't work. I know because I tried it in class and got the same results, didn't put a semicolon then. — nekro, Mar 26 '17 at 11:52
Now this is probably a dup of this http://stackoverflow.com/questions/5918079/fgets-doesnt-work-after-scanf I'd vote to close but already voted for a typo before the OP edited the post — StoryTeller - Unslander Monica, Mar 26 '17 at 12:00
But I didn't know what caused the problem. The semicolon was an oversight on my part. — nekro, Mar 26 '17 at 12:06
That semicolon *was* the problem. You got an answer to that. It doesn't mean you can edit the post to ask a completely different question about a completely unrelated problem This is not how one conducts themselves on SO. — StoryTeller - Unslander Monica, Mar 26 '17 at 12:24
I'll just make the same thread, but now without the semicolon to get the answer to that. — nekro, Mar 26 '17 at 12:28
