Re: [Dev-C++] function errors

[Per W. <pw...@ia...>]

I think you have picked the wrong line for the error. You have the error
in:

if(contin =3D=3D '')

You might specify an empty string with "" but you may not specify an empty
character with '' - a character is always a character - just as a number
always have at least one digit. There are actually multi-character
constants too, i.e. '\r\n' is a dual-character constant. However, these
kind of character constants are a bit special and normally requires
knowledge about byte-order of the machine to be used safely.

You might write one of:
if (contin =3D=3D '\0')
or just:
if (contin =3D=3D 0)

to test for a "null" character.
