Printing out 2 largest words

The program is meant to read text input and simply print out the lengths of the 2 longest words and the actual words themselves. The words, you can assume are no longer than 100 characters. The problem I have is more to do with obtaining the actual string to process (I'm not really flash with strings and co. )

Heres what I've done so far:

Code:

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

#define MAXWORDLEN 100

int main(int argc, char *argv[])
{
  char max_word[MAXWORDLEN], sec_word[MAXWORDLEN];
  char current_word[MAXWORDLEN];
  int max_length = 0, sec_length = 0;
  int length = 0;
  int input = 0;
  
  printf("Input words here: \n");
  do {
  // ****** PROBLEM HERE **********
  while (current_word = gets(stdin)){
    // check if it contains a space, which means its a word
    if (isspace(current_word) == 1)
    {
        // test for length
        for (int i = 0, length = 0; current_word[i] != NULL; i++, length++)
          ;
        // if biggest store in max_word[]
        if (length > max_length)
        {
                sec_length = max_length;
                max_length = length;
                strcpy(max_word, current_word);
        }
        // test if second biggest, if yes store in sec_word[]
        else if (length > sec_length)
        {
                sec_length = length;
                strcpy(sec_word, current_word);
        }
    }
    
    printf("Press 1 if you want to exit!\n");
    scanf("%d",&input);
  } while (input != 1);  // terminates when input == 1
  
  return 0;
}

I know that while() line is totally wrong haha, but how could I change it so that it reads a character and checks if the character is a space/tab or not (using isspace()) and then store it in the current_word[] string. If isspace() returns a 1, the rest of the code should work.. unless I missed out something small or big

Any suggestions would be greatly appreciated!

Lucky for you, there's a FAQ link on exactly this topic.

Quzah.

Blah I could only see the C++ version of doing it when I browsed through the faq but thanks *off to read it*
