Help setting a hidden word

mcdef

I am trying to write a hangman program that has only two functions other than main.

One of the functions:
void sethiddenword(char hidden[]);
is supposed to randomly assign a word to hidden. I have a list of 10 words i would like to use but can't use a control statment to set one of them into the array.

So far i have written
void sethiddenword(char hidden[]){
int rnum;
srand(time(0));
rnum = rand() %10;
}

This gives me the random number but i dont know how to assign the words to hidden. If you can do it with control statements i would like to see that. Either way, thanks.

Do you have a string array of 10 words? If yes, then you can have the index be the random number.

Expand|Select|Wrap|Line Numbers

 
void sethiddenword(){     // no need to pass an array

      int rnum;

      srand(time(0));

      rnum = rand() %10;

      string hidden = wordlist[rnum]; //you can do it with strings

      return hidden;

                 or

      char hidden[] = wordlist[rnum];       // or with char arrays

      return hidden;

}

That's what I did when I made my hangman. Also, you might want to change the function from a void to string return or a char array so you can return the word to main. I recommend using strings if you are using C++ but you can also do it with char arrays.

I have to do it in just C i cant do it in C++ so i guess i have to use char arrays. I do not know what a word list is, but i have 10 words on paper that i can use, like "computer", and "hello", i do not know how to bring them into th program without doing something like.
char wordone[size] = "word"; 10 times.

Well you can store the words in a text file and read them in to an array from the file. That can help when you decide to add more words.

Expand|Select|Wrap|Line Numbers

 
int count = 0;    //used to store index in array

ifstream file ("location_of_file");

while (!file.eof()){

    getline(file, wordlist[count]);     //wordlist is an array

    count++;}   //increment index

file.close();   //important to close file

Hope that helps.

I dont think we are allowed to use file i/o. How do you set, inside of sethiddenword(), an array of char strings. Like if the array is hidden, how can i set 10 words to 1 array. ie. hidden[0] = "word1", hidden[1] = "word2", i know that this will not work because the number inside the array is the size of the array.

You can declare the array like this:

Expand|Select|Wrap|Line Numbers

 
char* hidden[10];

//that makes it an array of char arrays

then:

Expand|Select|Wrap|Line Numbers

 
hidden[0] = "word1";

hidden[1] = "word2";

etc.

Does that work for you?

hidden[1] = "word2";

etc.

Does that work for you?

if my function is
void sethiddenword(char hidden[]){
int rnum;
char *words[10];
srand(time(0));
rnum = rand() % 10;
printf("%d\n", rnum);
words[0] = "clemson";
words[1] = "tigers";
printf("%s\n", words[0]);
}
The printf stuff is just to see if my code worked. How do i assign the word to hidden[].

hidden[] = words[rnum]; Does not work?

You can either try:
hidden = words[rnum];
and make the arguement from char hidden[] to char *hidden which I'm not sure will work,

or
have the function return the array like this:

Expand|Select|Wrap|Line Numbers

 
char* sethiddenword(){

    int rnum;

    char *words[10];

    srand(time(0));

    rnum = rand() % 10;

    words[0] = "clemson";

    words[1] = "tigers";

    char hidden[] = words[rnum];

    return hidden;}

    words[1] = "tigers";

    char hidden[] = words[rnum];

    return hidden;}

can i PM you what i have so far so you can get an idea of what my problem is.

I changed it to hidden = words[rnum] and that worked.
but when i call sethiddenword from my main function it doesnt not return the value of hidden.
