Question

C. how do i print out a sentence that the user typed in?

so far this is what i have

char sent[100];

printf("type a short sentence: ");
scanf("%s", sent);

prtinf("%s", sent);

problem is it only print out the first word =/

Answer 1

The reason it is only capturing the first word is because scanf only reads up to the first whitespace or newline.
You can try doing something like:
scanf("%[^\t\n]s", sent);

Answer 2

you may also use fgets(), a nice alternative to scanf() if you need to get strings: http://www.cplusplus.com/reference/clibrary/cstdio/fgets/


fgets reads until you enter a newline, until EOF is reached, or until n-1 characters (n is the second argument to fgets) have been read so it should accept tabs and spaces

Answer 3

Make sure you specify "stdin" as the stream to pick up what the user types in, and make sure the the string is big enough for whatever limit you prescribe.
