Getting scaf to accept strings with spaces in them?

How do I get scanf to accept strings with spaces in them, for instance 'Hello World,' whereby it'll take the whole sentence and not just the first word.

Thanks

scanf("%s %s", variables);

but then you need to know how many words there are going to be.

use

gets, or fgets

Code:

---

char string[256];
fgets(string, sizeof(string), STDIN);

---

Is gets a reliable function to use? I heard its not. Is it reliable to use in coursework?

Never ever use gets(). Use fgets() instead.

How do you end a sentence? What you want to do moves into the realm of advanced scanf usage, where you'll be relying heavily on scansets. To read an entire line with scanf, assuming a buffer of size 1024, you could do this:

Code:

---

scanf ( "%1023[^\n]", buffer );

---

To read a whole sentence, you stop at the first sentence terminating punctuation character:

Code:

---

scanf ( "%1023[^.?!]", buffer );

---

Note that in both cases, the character that scanf stops at is left in the stream. Of course, for some reason a lot of people have trouble getting scanf right, so you'd be better off using fgets and then parsing as necessary.

stdin isn't capitalized in standard C.
