Scanning an inputted array of words, and separating each word into a new array?

[Loopah]

Is this possible? I would like to have a user input a sentence, and then have each word in that sentence be put into its own array.

[WolfPack]

Yes it is possible.

[SpS]

make use of string class and its functions...it is very easy

[Loopah]

Oh, thanks for the information. I will be sure to look at the string class tonight when I get a chance to finish my program. I assume you are talking about the <string.h> class right? If so, I have tried using the strtok function to break each word into a function. After trying this I cannot seem to figure out how to separate each token into a new array. Or is that even needed to do what I need to do? Do I need to use something other than strtok?

[SpS]

I was talking about <string>

[Loopah]

Oh, I have never heard of that. I am using C, not C++ if that makes a difference. Do you know about the strtok function that I am speaking of?

[Dave Sinkula]

Post your attempt. The basics are something like this:

static const char delim[] = " \n";
      size_t size = 0;
      char word[10][20], *ptr = strtok(sentence, delim);
      while ( ptr != NULL )
      {
         strcpy(word[size], ptr);
         if ( ++size >= sizeof word / sizeof *word )
         {
            break;
         }
         ptr = strtok(NULL, delim);
      }

Ok, this is my program. I included the entire thing, because when I went to add the part in the main() function about choosing which game to play, it gives an error when I run it. Something is wrong and I have no clue what it is. My attempt at the arrays is in the cellPhone function which is not complete.

Also my compiler is giving me an error if i try to shorten the line length of the menu by entering half of it to a new line. Why is it doing this?

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

void nameGame();
void pigLatin();
void changeLatin(char [], int);
void cellPhone();
void cellButtons(char [], int);

main()
{
	int input = 0;

	printf("\n\tEnter your choice:\n\t1. Name Game\n\t2. Pig Latin\n\t3. Text Messaging\n\t4. Exit\n");

	scanf("%d", &input);

	while (input != 4)
	{
		if (input == 1)
			nameGame();
		else if (input == 2)
			pigLatin();
		else if (input == 3)
			cellPhone();
		else
			printf("Invalid choice.  Enter a number 1-4.");

		printf("\n\tEnter your choice:\n\t1. Name Game\n\t2. Pig Latin\n\t3. Text Messaging\n\t4. Exit\n");
		scanf("%d", &input);

Ok, I ran your code through my program in place of mine for the pigLatin() function and it works, but how do I access each word's array? I need to modify each word.

[Dave Sinkula]

From my earlier mockup:

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

int main(void)
{
   char sentence[200];
   puts("enter a sentence:");
   fflush(stdout);
   if ( fgets(sentence, sizeof sentence, stdin) != NULL )
   {
      static const char delim[] = " \n";
      size_t i, size = 0;
      char word[10][20], *ptr = strtok(sentence, delim);
      while ( ptr != NULL )
      {
         strcpy(word[size], ptr);
         if ( ++size >= sizeof word / sizeof *word )
         {
            break;
         }
         ptr = strtok(NULL, delim);
      }
      puts("words are:");
      for ( i = 0; i < size; ++i )
      {
         puts(word[i]); /* access to each word */
      }
   }
   return 0;
}

/* my output
enter a sentence:
The quick brown fox jumps over the lazy dog.
words are:
The
quick
brown
fox
jumps
over
the
lazy
dog.
*/

Oh nice! Any idea on why my program gets thrown into an error when I run it with the while loop in main()?

[Dave Sinkula]

First I think you need to obtain user input more cleanly. To that end, scanf is not your friend.

[Loopah]

Hmm, that is they way we were always taught to get input. Not sure of another way to get input. That way has always worked in the past.

[Dave Sinkula]

Well, there is lots of bad information out there and plenty of bad teachers.

[Loopah]

So I should use sscanf probably?

[Dave Sinkula]

Generally fgets with sscanf is a better idea. Here are a couple more:

Thank you very much for your help! I appreciate it. You guys here are very helpful, and I hope to do my part in the helping soon as well.
