C++ Programming issue

Apr 14th, 2007

I am writing a simple (extremely simple) hangman program. Basically the user inputs a word, then they have double the number of letters in the word for guesses (for instance if the word has 7 letters they get 14 guesses). Please don't ask why I want the user to input the word, because it is a homework assignment and that is what the instructor is wanting us to do.

I am having a problem getting the strlen() to write the value to another variable so that I can double it to get the # of guesses and also get one "_" per letter.

If you're using C++, you should probably be using the std::string type rather than C-style strings (char*).

And your line strlen(getWord) = numLetters; is backwards. Try flipping it around.

>getWord.length();
This line doesn't do anything.

And a couple of other things: change "void main" to "int main" and get rid of <conio>.

Hello frens

I m a bit new to programming in C++, but still from what i understood this is a pretty good program. Keep posting such programs they will help newbies like me to understand the programming tricks.

As my small contribution i suggets a site www.ITpalace.com , this is a quite informative site and will provide you some interactions regarding programming.

Ok, now I am having issues with more sections of code. The first I am trying to create a function that will take getWord.length() and will output the "_" one for each letter remaining. So if the word is say "hippo" and you guess "p" it would look like _ _ pp_.

Warning W8070 hangman1a.cpp 72: Function should return a value in function dashes()
*** 1 errors in Compile ***

Aside from the undefined symbol issue, my problem is that I need to call numLetters for the dashes, but at the same time I need to decrement the number of dashes by the number of letters that are displayed. I also need a method by which to display the correctly guessed letters in the correct location. So that "hippo" doesn't show up as pp_ _ _ when you guess "p". To resolve this issue would it be feasible (or possible) to change the string into a char array, or is there a better method to do this?

Re: C++ Programming issue

The string class overloads the [] operator so individual characters can be accessed just like with a char array. the c_str() method will return a const char* to the char array embedded within the string object if you want to change the string into a char [].

You could do something like this:

string displayString ;
int len = getWord.length();
for(int i = o; i < len; ++i)
displayString += "_";

now displayString has as many underscores as there are letters in getWord. And you can display what evers in displayString by something like:

cout << displayString;

then when user inputs a valid guessLetter you loop through getWord and if guessLetter equals getWord[i] then you assign guessLetter to displayString[i]. After loop is completed you can then just output displayString with all the correct guesses in their appropriate slots with remaining underscores intact.

Why not have an answer string which you load with '_'s and just output that string. As correct guesses are made, replace each '_' with the letter.

Re: C++ Programming issue

#10

Apr 24th, 2007

ok, I have completely changed the program. I now have three components that work seperately, but not when I attempt to mesh them.
Here is the code individually. Keep in mind that each seperate function is in fact written as a seperate program and when I mesh them I do change variables a bit so that there is no multiple declarations and such. The error I get is Invalid indirection in function main().

Can someone please help direct me in the proper way to mesh these three pieces together...I was thinking creating 2 parts as header files or some such method.

I am also thinking I am not needing all three parts. Basically I am trying to create the hangman program that uses a users input (the instructor) who will then "guess" the input word, with a mix of capital and non-capital letters and have the program return the word as it is entered (that is if it is Antique it would come out as Antique, AnTiQuE would come out as AnTiQuE and so on) but as long as the letters are there in the correct order it would come out as correct. Also the number of guesses is decremented by 1 each guess. If guesses run out...you are hung. I cannot seem to mesh the parts to come out with a whole though.

This is the attempt at meshing the code:
which causes the aforementioned error
