Whenever compiler found special character .. it gives these king of compile error .... what error i found is as following
error: stray '\302' in program and error: stray '\240' in program
....
Some piece of code i copied from chatting messanger. In messanger it was special character only.. after copiying into vim editor it changed to correct character only. But compiler was giving above error .. then .. that stamenet i wrote mannualy after .. it got resolve.. :)
