Why I can add a c behiand a charactor, when I create a defalt value of a string variable

Why I can add a c behiand a charactor, when I create a defalt value of a string variable
"."c is a legal defalt value of a string variable.
Is there any different between “.” and "."c when I declare the default value of the variable?
