Home Forums C Programming WhiteSpaces and Blank Lines Re: Re: WhiteSpaces and Blank Lines


I’m not sure what compiler your using but the include file ctype.h has a macro called isspace() that can be called on characters , like:

The definition is listed as

The isspace() function returns non-zero if its argument is some sort of space (i.e. single space, tab, vertical tab, form feed, carriage return, or newline). Otherwise, zero is returned.
