As we all know, C uses "/" to escape, the following is his common escape form
Side sequence: Description
/ N wrapper
/ T horizontal tab
/ r Enter
/ a warning sound
// /
/ ""
/ ''
But when using characters, pay attention to:
CHAR A = ''; // a space
CHAR B = ''; // Two spaces
The above A and B are the same, all spaces, but
CHAR C = '/ n'; // / n has a space
CHAR D = '/ n'; //// has a space
Char E = '/ n'; // No space
The above C and D are spaces, only E is a newline.
Be careful when using it.
(The above code runs on VC7)
