How to use struct for this purpose?

STEPS:
1. Declare an input string as follows:
char InputString[] = "the dog thought up a lie done";
Note that "done" is the last word that appears in the sentence, but not part of the sentence itself.

2. Use strtok() to extract each word from the InputString and store it in the WordList. (Assume space is the only delimiter separating the words).
Note: to access the "Word" array inside WordList use the "dot" operator. (eg. strcpy(WordList[n].Word, "hello"); )
Do not store the word "done" in the WordList, we are simply using it to mark the end of the sentence.

3. Print the contents of the WordList.

Here is what is done so far

Code:

---

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


struct WordStruct      // Structure Definition
{
        char Word[51];  // A "Word" is a string that can store up to 50 characters and the null string terminator
        int length;            // Number of characters stored in the Word (not including null)
} WordList[25];        // Declare an array to store 25 words

typedef struct WordStruct WS;

//void Printit(WS t);

int main()
{

  char InputString[] = "the dog thought up a lie done";
  int i;

  WS s1;
  s1 = InputString;


  /*WordList[0] = strtok(InputString, " ");
  for(i=1; i<9; i++)
  {
        WS[i] = strtok(NULL, " ");
  }
  */


return 0;
}

---

clearly not doing it right. I thought I could get it into the array like this, in RED.

Someone please help. Structures is giving me a head ache.

Why would you think that? strtok returns a character pointer. WS[i] isn't a character pointer. Also, strtok doesn't actually duplicate or copy anything. It uses a local static buffer to contain a portion of its arguments. You still have to end up copying some place, and you have to do that yourself. Furthermore, arrays start at 0 not 1.


Quzah.

Structures shouldn't give you a headache.... structures are very simple things. I think you have a headache because you think the struct will do a lot more than it does.

I'm not sure I understand what you're trying to do though, so apologies if I missed the point.

You have
Wordstruct: a struct which contains a char array and an int
WordList: An array of 25 these structs

So to copy the words from InputString to Wordlist you'll have to strcpy one element at a time.

Code:

---


  strcpy(WordList[0].Word, strtok(InputString, " "));
  WordList[0].length = strlen(WordList[0].Word);
   
  for(i=1; i<9; i++)
  {
      strcpy(WordList[i].Word, strtok(NULL, " "));
      WordList[i].length = strlen(WordList[i].Word);
  }

---

You can't take a char array and assign it to an array of a different type. Nor can you do

Code:

---

struct WordStruct myws = "some string";

---

The compiler doesn't know you mean "copy the string into the char array and store the length in the int". How could it?

I see where I went wrong.

@smokeyangel
Thank you for showing me this. I appreciate this more than you will know. I believe I understand now how you went about this.

I followed that with this.

Code:

---

for(i=0; i<10; i++)
  {
      printf("%s\n", WordList[i].Word);
  }

---

Once again, thank you so much for taking the time for this.
