'Single-Quotes' and "Double-Quotes" ...?

[BenderBendingRodriguez]

hi, i am new to this board and to the judge, but i'm also interested for solving some problems.

so, i have a question about 'Single-Quotes' and "Double-Quotes" in C++..
what is the difference between 'Single-Quotes' and "Double-Quotes" ...?

if my code looks like this:

Code: Select all

 char c;
... // c is an character, for example 'a'
if(c == "\n")
{ ...

...i get an ErrorMessage like this while compiling: "cannot compare char-pointer with constant string"

then i use the 'Single-Qutes' instead so that the one line looks like this:

Code: Select all

if(c == '\n')

...and there is no problem.

what is the exactly difference between 'Single-Quotes' and "Double-Quotes" ...?

Single-quotes are used to specify character constants while double quotes specify string constants. So the behaviour of your compiler is exactly what should be expected
