What does it means?

#define abc '\xE8'
# 2  
Old 03-22-2011
This is a pre=processor macro replacement
Code:
perl -e 'print chr(0xE8), "\n";'
è

So you have a constant abc which is replaced by the e-grave character before compilation.

that means can we say that the variable 'abc' is assigned with hex value.....??

No, there's no variable 'abc'. abc is a text block that will be replaced by the pre-processor. It's like telling the compiler to run a sed search/replace before starting compilation.
