Question

In this segment of code the scanf is requesting twice and I am not sure what could be causing it to do so.

int t;
for(t = 0;t<5;t++)
{
    //scanf requests twice for some reason
    scanf("%s ",input);
    fprintf(fp,"%s ", input);
    printf("%d Word(s)\n", (t+2));
}

and the output is
(words in quotes are entered in by the user)

"hello"
"world"
1 Word(s)
"how"
2 Word(s)
"are"
3 Word(s)
"you"
4 Word(s)
"lostword"
5 Word(s)

And

"hello world how are you "

would be given back to me and saved into the file.

Remove the whitespace in scanf.

Change:

scanf("%s ",input);

to:

scanf("%s",input);

Due to the space, scanf keeps skipping whitespace characters until it reads something that’s not a whitespace (after reading one string for %s).
