dataoutputstream. Inputstreamreader and inputstreamwriter are used to convert a byte stream to a bytes stream based on the specified character sequence set, for example: Inputstreamreader in = new inputstreamreader (system. in, "gb2312"); outputstreamwriter out = new outputstreamwriter (system. out, "gb2312"). For example, the following sample Java encoding meets the requirements: // Read. JavaImport java. Io .*;Public class read{Public static void main (string [] ARGs)Throws ioexception{String

Finally, I implemented it using C ++ because STL does not contain the Regular Expression, so I used the Regex ++ in Boost. But because it is not very familiar, the code is very poor and I will read it. Haha. # Include # Include # Include # Include Using namespace std; Void readFile (const char * filename, string str );Void writeFile (const char * filename, const string str );Void filter (const string input, string output ); Int main (int argc, const char * argv []){If (argc {Cout Return 1;}S
