Double Matches

How can i make it so it doesn't output the same word more than once? And to make it go back to the entering input until they press CTRL+Z as the input?

Code:

---

#include <stdio.h>

/* This function takes all the characters and makes them UPPERCASE */
int LowUpp(int ch)
{
        if ( 'a' <= ch && ch <= 'z' )
        {
                return (ch + 'A' - 'a');
        }
        else
        {
                return ch;
        }
}


char c;

int main()
{
        int LowUpp(int ch);

        char word[23];
        char userstring[1024];
        char Array[1024][100];

        int wordcount = 0;
        int charcount = 0;
        int wordnumb = 0;
        int i = 0;
        int j = 0;
        int row = 0;
        int column = 0;

        printf("Word & Character Counter\n\n\n");
        printf("Enter your input ([CTRL+Z] To Quit): ");

        if(fgets(userstring, 1024, stdin) == NULL)
                return 0;

        printf("\n\nWord Count                ");
        printf("Word                        ");
        printf("Character Count        \n");
        printf("---------------------------------------------------------------\n");

        while(userstring[i] != '\0')
        {
                if((userstring[i] != ' ') && (userstring[i] != '\n') && (userstring[i] != '\t'))
                {
                        charcount++;
                                word[j++] = LowUpp(userstring[i]);
                }
                else
                {
                        wordnumb++;
                        word[j] = '\0';
                        Array[row][column] = word[i];

                        if(charcount < 8)
                                printf("%d\t\t\t%s\t\t\t%d\n", wordnumb, word, charcount);
                        else
                                printf("%d\t\t\t%s\t%d\n", wordnumb, word, charcount);

                        charcount = 0;
                        wordcount++;
                        j = 0;
                }
                        i++;
        }
       
        printf("---------------------------------------------------------------\n");
        printf("Total Words:  %d\n\n", wordcount);
       
        return 0;
}

---

Code:

---




int LowUpp(int ch)
{
        if ( 'a' <= ch && ch <= 'z' )
        {
                return (ch + 'A' - 'a');
        }
        else
        {
                return ch;
        }
}

Why" reinvent the wheel " here. Use one of the character classification functions (toupper or tolower) found in <ctype.h>

What OS is this on? If you plan ondoing Ctrl+Z in Linux, you need to setup a signal handler I beleive. Ctrl+Z is used for suspending and application and you want to avoid that.

(someone, correct me if i'm wrong please)

Windows. And for the assignment I can only use stdio.h So i had to do that function.

Windows uses CTRL-Z ...*nix uses CTRL-d <return>

Corrected :D

Store the words in a 2-d array, and before you print each one, check the array to see if your word is in there. You need a seperate function to do the checking. Just pass it the 2-d array name and the char array holding the need word, and get it to loop through the 2-d array doing strcmp()'s on each entry.

>make it go back to the entering input until they press CTRL+Z as the input?
You need a while loop, like this:

Code:

---

while (fgets(buf, sizeof buf, stdin) != NULL)
{
    /* Process words here */
}

For added fun, use a hash table instead! Maybe you'll get extra credit. ;)

Quzah.

If you are talkinga bo end of file then you are mostly right (no <return in linux>
I was talking about suspending the applicaiton, inwhichc ase ^Z is it in linux, but thanks for the clarification.
