accessing user entered array elements by index?

Hi,
If you initialize an array of strings like:

Code:

---

char string[4][10] = {"monday", "tuesday", "wednsday", "thursday"}

---

Each element can be accessed by index. But is there a way to make an array that has its contents entered by the user accessable by index, for instance, if the user entered a sentence, could each word be accessed by index? like:

Code:

---

char string[21];

gets(string);

"today is thursday"
  0    1    2

printf("%s" , string[2]);

---

Any help would be appreciated.

Code:

---

        char string[3][10];

        gets(string[0]);
        gets(string[1]);
        gets(string[2]);

        printf("%s\n%s\n%s", string[0], string[1], string[2]);

---

Also, gets is bad.

so each word would have to be entered by a separate prompt?

Or a loop.

Code:

---

for(i = 0; i < 3; i++)
{
        scanf("%s", string[i]);
}

---

I see. But there is no way you can enter the sentence at once and be able to access each word as an individual element?

Sure. Read it all into one buffer and then split it up, copying it to the appropriate array.


Quzah.

This is crappy.

Code:

---

gets(string[0]);

---

This is one notch better than crappy, but still crappy.

Code:

---

scanf("%s", string[i]);

---

There is an FAQ.

ahh yes,
I have experienced the problem with gets() already. The program crashes with a windows error if the input is to large.

I'd have thought scanf("%s", foo) would be on the same crappiness level as gets(foo) since they're both crap for the same reason. :p

fgets() -- non-crappy version

Everything becomes clear if you read the FAQ . . .
