help with this code ...

I am trying to make a simple game of Hangman. The following code does run
when compiled. It is missing the "meat" of the game. What I need to figure
out is how am I going to check to see whether the letter entered by player
is in the answer or main word of the game. Oh and to run this code youll
need a text file named words.txt in the same directory as the .exe. This is
where it gets the words from.

Okay, to be honest, I didn't look at all your code or try to run it.
What I did look at looked fine, though.

Checking a letter against the word or phrase trying to be guessed is
fairly straight-forward. All you need to do is check the character
entered against the characters in the string. This is about how you
would do it:

char enteredCharacter;
char stringToGuess[] = { "W", "o", "m", "b", "a", "t" };

// get user input here

int guessLen = strlen( stringToGuess );
int numOccurances = 0;
for( int i=0; i < guessLen; i++ )
{
if( toupper(stringToGuess[i]) == toupper(enteredCharacter) )
++numOccurances;
}

// check to see if they guessed correctly
if( numOccurances > 0 )
// guess correctly method
else
// guess incorrectly method

The toupper simply converts both characters to a case-insensitive
compare. That's about it.

Line 1 should be #include "iostream.h"
I'm not quite sure how this compiled correctly. But, since it did, I suggest
you use Frecklefoot's method. Since you want to convert things to
lower-case, use tolower(); instead of toupper();
This chunk of code is really unnecessary then:
while (letter<65||(letter>90&&letter<97)||letter>122); /*if
they do enter a letter then make it lowercase*/
if(letter>=65&&letter<=90)
letter=97 +letter - 65;
//changes fom uppercase to lowercase
if(letter>=65&&letter<= 90)
letter=97+letter-65;
return (letter);
}
I hope that I was of help :-)
