Hi,
char a = '\c'; //line 1
char b = '\r';
char c = '\"';
char d = '\b';
char e = '\p'; //line 5
why we use \ inside the quotes is to the characters ', ", ` and for backspace (\b), carriage return (\r) and line feed (\n).
I think (\p) does not mean any thing. thtsy it is throwing error.
char a = '\r'; //line 1
char b = '\b';
char c = '\"';
char d = 'b';
char e = 'p'; //line 5
if you execute this, it wont show the error.
