C scanf with spaces problem [duplicate]

Answer 1

Well bookname surly is some kind of char ;-) Point is that scanf in this form stop on the first whitespace character.

You can use a different format string, but in this case, one probably should prefer using fgets.

scanf really should be used for "formatted" input.

Answer 2

Use fgets() instead of scanf()

Answer 3

The %s conversion specifier causes scanf to stop at the first whitespace character. If you need to be able to read whitespace characters, you will either need to use the %[ conversion specifier, such as

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

which will read everything up to the next newline character and store it to bookname, although to be safe you should specify the maximum length of bookname in the conversion specifier; e.g. if bookname has room for 30 characters counting the null terminator, you should write

 scanf("%29[^\n]", bookname);

Otherwise, you could use fgets():

 fgets(bookname, sizeof bookname, stdin);

I prefer the fgets() solution, personally.
