Yes compiler always ignores the first '\' and if it finds a recognizable character after this escape sequence . it will interpret it. Otherwise it just dumps it according to predefined semantics of machine code generation.But I would suggest everyone in this group to try out http://www.codepad.org Where you can easily test the code in any language of your choice. It must be using gcc compiler. Thanks
