Using fgets

[coding1000]

hi,
just trying to input a word and returning the number of letters the word has.
For some reason, my i counter always gets to 1 higher than the actual number of letters.
Why is this happening? (i understand it is easier to use strlen but just want to know why this is happening).

#include <stdio.h>
int main(void) {
char input[1042] = {};
printf("Input word:");
fgets(input, 1042, stdin);
int i = 0;
while (input != '\0') {
i++;
}
printf("%d", i);
return 0;
}

Please use code tags next time, it turned into italics halfway through and dropped the array index bit. It's one greater because there's a newline character at the end of your input. Throw a line like the following at the beginning of your while loop to inspect it.

printf("i = %d (%c)\n", i, input[i]);
