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

    >>how can i make it so it doesn't output the same word more than once?
    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 */
    }
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

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

    Hope is the first step on the road to disappointment.

    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.
