find palindromes in the row and display them

A string consisting of words, no longer than 100 characters, is supplied. Words consist of Latin characters and are separated by a single space. It is necessary to output to the standard output stream a string containing only the words palindromes.
The source data must be read into memory as a whole and all manipulations must be carried out in memory, the result obtained in memory and then printed.

#define _CRT_SECURE_NO_WARNINGS

#include <stdio.h>

#include <stdlib.h>

#include <string.h>



int check(char str)

{

    int i, length;



    length = strlen(str);



    for (i = 0; i < length; i++)

        if (str[i] != str[(length - 1) - i]) return 0;

    return 1;

}



int main(void)

{

    char str[100];

    char* t;



    gets(str);

    t = strtok(str, " ");





    while (t != NULL) {

        if (check(t) == 1) {

            printf("%s ", t);



        }



        t = strtok(NULL, " ");

    }

    _getch();

    return 0;

}

this is my code (it fails the tests)
Please help me fix the code

Never ever use gets! It's a dangerous function that have even been removed from the C standard. Use e.g. fgets instead.

I don't know what else you can change (thanks for the fgets I will definitely change it), who can email me the corrected code please

Why for (i = 0; i < length? length/2 seems enough.

Instead of fgets use function getline(&buffer, &size, stdion) for example.

Your for loop in the check function works fine but resolve another problem, than that you expected.

Palindrome a word or group of words that is the same when you read it forwards from the beginning or backwards from the end.

this code it works, try to enter any words of palindromes and it will output them if this is true (but for some reason my tests do not pass this code 0/16)
