Character constants are "mini-strings".  Each must start and end with a quote.

Strings use double quotes.  "This is a string" must start end and with the double-quote character for C to properly recognize the value as a string.

Character constants use single quotes.  'A' is the proper way to quote a single character.

Here's how the two look in C code:

char Name[20] = "My Name";
char Grade = 'A';

if (Grade == 'A')
  strcpy (Name, "Kdo");

Good Luck,

Try doing a search for the single quote character  '

Mine is near my enter key.  It is possible you have hit it on occasion.

ok a character did not mater.  Just one thing.  Why did that not show up as a parse error?

You may not be *intending* to use any characters. However, the error message indicates that the compiler has come across a line that has a quote character in it. Since it doesn't find a second one, the compiler is constrained to assume that it is missing.

Quotes can sometimes be hard to see. If the compiler tells you what line the problem is on, it may be simpler to delete it and retype it.

I'm not quite sure what you mean by "parse error". Isn't "unterminated character constant" a parse error?
