Suggestions for my Code for Hangman /* Ansi C-based */

Lan · #1 14-Mar-2006, 10:18

It is a single player hangman that uses text files to read phrases that will be used for the game and can /* store top 5 players in a text file */ and uses functions and a library for other utilities.

This is the main.c

CPP / C++ / C Code:

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

#include "util.h"

#define MAX 80

typedef struct {
        char name[30];
        int score;
        } players;

char Phrase[MAX], temp1[MAX], storage[26];
int choice, chance1, tries1, diff;
players player;

void printSpace();   /* Tools that the program needs. */
int getCharacter();
int checkCharacter(char guessedChar, int noOftries);   

int menu();          /* These are the main functions of the game */
int diffSelect();
int playGame();
int mainGame();

int main()
{   
   printf("\n\n");
   printf("   |***********************| \n");
   printf("   \\* Welcome to Hangman  */\n");
   printf("   /*           by Lan    *\\ \n");
   printf("   |***********************| \n");
   printf("\n\n");
   menu();
}

int menu()
{
   int x; tries1 = 0, choice = 0;
    
      printf("\nPlayer Mode\n");
      printf("  [1].Play\n  [2].High Scores\n  [3].Im Tired\n\n");
      printf("Select you choice: ");
      scanf("%d", &choice); 
		
      if(choice==1)
	diffSelect();
      else if(choice==2)
             { displayHigh(); menu(); }
      else
	return 1;
}

int diffSelect()
{  
   char dummy[50];
   
   putchar('\n');
   printf("You chose to play.\n");
   printf("\nSelect difficulty\n  1(Hard) - 9(Easy) : ");
   scanf("%d", &diff); chance1 = diff+5;
   printf("Player name: ");
   scanf("%s", player.name);
   
   randPhrase(Phrase);
   playGame();
}
       
/* int randPhrase()
{   
   putchar('\n');
   printf("Choosing Random Phrase...");
   strcpy(Phrase, "Hello");
   printf("Done.\n\n");
   playGame();
} */

int playGame()
{
   int x, y;
   for(x = 0; x < strlen(Phrase); x++)
   {
      temp1[x] = '_';
      Phrase[x] = toupper(Phrase[x]);
   }
      temp1[strlen(Phrase)] = '\0';  
      
      
   y = mainGame();
   
      if(y)
      {
         printSpace();
         printf("You win %s , you got %s in %d tries.\n", player.name, Phrase, tries1);
         player.score = (100-(10-chance1)*10)+10;
         printf("Your score is %d points\n\n", player.score);
         menu();
      }
               
      else
      {
         printSpace();
         printf("You Lose %s, no points for this game.\n", player.name);
         printf("The correct phrase is \"%s\"\n\n", Phrase);
         menu();
      }
}

int mainGame()
{
   int x, y = 0, cond1; char guess;
   

      while(chance1>=1)
         {
            if(!strcmp(temp1, Phrase)) break;
            y = 0;
            printf("\nHint: %s\n", temp1);
            printf("Guess a letter: ");
            guess = getCharacter(); guess = toupper(guess); tries1++;
            
			for(x = 0; x < strlen(Phrase); x++)
			{
				if(!checkCharacter(guess, tries1))
				   { printf("Error. Already Guessed.\n"); y--; break; }
				else if(guess==Phrase[x])
				   { temp1[x] = guess; y++; continue; }
			}
					 
            if(y>0) praise();
            else if(y==0)
            {
               insult(); chance1--;
               printf("You got %d chance/s left.\n\n\n", chance1);
            }	 
         }
          
      if(!strcmp(temp1, Phrase)) return 1;
      else return 0;
}

void printSpace()
{ printf("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n"); }

int  getCharacter()
{
    int ch;       
    do             
    {
       ch = getchar();        
    } while((ch <= 0x20)||(ch >= 0x7F)/* check above SPACE, below the last ASCII char */ );                    
    return ch;
}

int checkCharacter(char guessedChar, int noOftries)
{
    int x;
    
    for( x = 0;  x < strlen(storage); x++)
       if(guessedChar == storage[x]) return 1;
       else
       {
          storage[noOftries-1] = guessedChar; return 0;
       }
}
/* Im having problems implementing checkCharacter, what it exactly does is that it puts the scanned char at a string and makes it an error-checker if the guess is already guessed xD */

This is the util.h

CPP / C++ / C Code:

extern void randPhrase();
extern void praise();
extern void insult();
extern void displayHigh();

void randPhrase(char *array)
{
	int x=0;
	char *temp = { "Hello" }; 
 
	for(x=0; x<strlen(temp); x++)
	{
		array[x] = temp[x];
	}

	array[x] = '\0';
}

void praise()
{
char praise[5][20] = { "Good Job.", "Great!", "Amazing!", "Keep it up!", "Go go go!" };

   srand( time() );                           
   printf("%s.\n", praise[(rand()%10%5)+1]);
}

void insult()
{
char praise[5][30] = { "Think Again.", "Bah Humbug!", "You're a Big Joke", "Go Home.", "Press Ctrl+C." };

   srand( time() );                           
   printf("%s.\n", praise[(rand()%10%5)+1]);
}

void displayHigh()
{
   printf("Hello World.\n");
}

Please appologize if there are several mistakes in my program. It is currently under development. But that is the main program. My main objectives are to:

1. Have random praise or insult. /* Implemented */
2. Case insensitive character checking. /* Implemented */
3. Save the top 5 players in a seperate file. /* Under Debug */
4. Encrypton/ Decryption Scheme. /* Alpha Stage */
5. Use comments so the phrase will not be repeated. /* Not yet done. */
6. Use srand() to change the sequence of rand(). /* Implemented */

Suggestions, comments, additional codes, improvements is very much needed.

Please bear with the code. I haven't got the time to document it.

Thanks.

All I did was make it so that your code would compile cleanly without errors. There are still numerous warnings. Here is the code:

util.h

CPP / C++ / C Code:

#ifndef UTIL_H
#define UTIL_H

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

extern void randPhrase();
extern void praise();
extern void insult();
extern void displayHigh();

void randPhrase(char *array)
{
    int x=0;
    char *temp = { "Hello"}; 

    for( x=0; x<strlen(temp); x++ )
    {
        array[x] = temp[x];
    }

    array[x] = '\0';
}

void praise()
{
    char praise[5][20] = { "Good Job.", "Great!", "Amazing!", "Keep it up!", "Go go go!"};

    srand( time( 0 ) );                           
    printf("%s.\n", praise[(rand()%10%5)+1]);
}

void insult()
{
    char praise[5][30] = { "Think Again.", "Bah Humbug!", "You're a Big Joke", "Go Home.", "Press Ctrl+C."};

    srand( time( 0 ) );                           
    printf("%s.\n", praise[(rand()%10%5)+1]);
}

void displayHigh()
{

You've got globals, multiple statements on single lines, multiple variables declared on single lines, no return values for functions declared to return a value, you use single-line and multi-line conditional braces, in some cases you jam your variables and operators together and in others you separate them with appropriate whitespace, you were missing headers and inclusion guards...give it a bit more work and clean it up and we'll take another look at it, okay?

:davis:

Lan · #3 15-Mar-2006, 22:20

Well, thanks man..

It helped me a lot. Sorry for the trash... I will clean it up ASAP.

Err.. I have managed to clean it up and im down with the problem of how to restate an argument like this?

CPP / C++ / C Code:

temp[x] = toupper( temp[x] )

As of now, my only warnings are two of that type. Ansi C forbids braced groups to be used in an expression?

Lan · #4 16-Mar-2006, 10:01

Ive now encountered my second problem in decypting a text file. I managed to encrypt it by changing each character to it hex equivalent and decrypting it is successful. The problem is it doesnt have any newlines. So the multi-lined source file becomes a single line source file!

Encryption.c

CPP / C++ / C Code:

#include <stdio.h>

int main()
{

  FILE 	*Ptr;

  char	 Line[80];
  int x, length;
  /* ...	Open a file for output. */

  Ptr = fopen("hello1.txt", "w");
  
  while( gets(Line) )		/* Get data from stdin */
  {
	length = strlen(Line);
	for( x = 0; x < length; x++ )
    fprintf(Ptr, "%02x ", Line[x]); 
    putc('\n', Ptr);
  }
    putc('\b', Ptr);
    
  fclose(Ptr);
  
  exit(1);
}

Decryption.c

CPP / C++ / C Code:

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

main()
{
   FILE *source, *dest, *temp;
   char data[80];
   int hex;
   
   if((source=fopen("hello1.txt", "r"))==NULL)
   {
      printf("Error opening source file\n");
      exit(1);
   }
      
   if((dest=fopen("hello.txt", "w"))==NULL)
   {
      printf("Unable to write/create destination file");
      exit(1);
   }
   
   fscanf(source, "%x", &hex);
   while(!feof(source))
   {
      fprintf(dest, "%c", hex); 
      fscanf(source, "%x", &hex);
   }

   fclose(source);
   fclose(dest);
}

So a file with:
// Hello
// world
is encypted as:
// 68 65 6c 6c 6f
// 77 6f 72 6c 64
and decrypted as:
// helloworld

I want an expected output of:
// hello
// world

Any one?

Lan · #5 16-Mar-2006, 12:04

After cont's debugging, problem solved.

Thanks people.

Lan · #6 19-Mar-2006, 01:25

To prevent plagiarized codes, can the admin please erase my C codes? Because this hangman was assigned to be a project individually. Im afraid that someone can gain access to this codes with simple searches on google.

Ive done one and this thread showed on page 3. !

admin · #7 19-Mar-2006, 09:16

Unfortunately, I cannot delete the code. I am not obliged to do so.

This is why we exist... So (other) people can find things already being discussed and shared. We cannot control what people do with the information they find here.

This may be obvious but I'll state it again -- please refrain from posting or replying if you don't want certain information to be shared with others.

As far as I am concerned, you already did the responsible thing by suggesting / advising people what they can and cannot do with your code examples inside this thread.

Lan · #8 19-Mar-2006, 19:29

I realized that after posting the last post.

Oh well, what done is done. Its up to them now.

BTW, thanks.
