Hi,
JQ+ 952739446690
Which of the foll are invalid?
a) char b='\u0062'
b) char \u0062='b'
c)ch\u0061r b='b'
d)char lf='\u000a' \\ '\u000a' represents linefeed
JQ+ says only 1,3 are correct . 4 is not .It states " Though \u000a represents a line feed it is translated to a line feed in the first parse so it puts a line feed wherever it occurs. In
this case we should use escape sequence : char lf = '\n';
why is it then that we cannot represent it by a unicode value. Is there any rule that sequences like \n,\t,\b etc can't be represented in unicode?
Thx in advance

The reason is such unicode sequences convert to the actual chars before the compilation takes place so
char lf='\u000a'; this is is equivalant to:
char lf='
';

BTW, 2 is also correct. The s/w shows that correctly.
