palindrome function

ok here is how i figure i would do it...

get input
determine lenght of string and reverse it bu looping a decreasing for loop and concatenating the strings into a second string
eg: text[100] added to reversedstring then text[99] added to reverstring and so on...

then i would use the strcmp function to test for equality and see if it is indeed a palindrome... is this the best way to do it? anyone else have some faster or better pseusocode also i dont know how to determine the lenght of a string :(

use strlen(string) for length
strcmp(str1,str2) for cmp

yeah its fast but more mem will be used

or you could use 2 loops one from 0 and incrementing and the other one from 99 and decrementing; comparing 0-99, 1-98 so on to see for palindrome.

This has been handled many times before, just click on this to see.

ok no i have a litle problem the uncommented lines i do not understand... what does tolower do?

Code:

---

char* start = text; //pass the whole array into the start variable
  char* end = text + strlen(text) - 1; //pass the last charecter of the array into end
  while(end > start)
  {
      if(tolower(*start) != tolower(*end))
      {
          return(0);
      }
      end--;
      start++;
  }
  return(1);

---

tolower will return the upper case equivalent of the character that you pass to it.
