I would like to write a console copy program in C++ that copies a file into another file like linux or windows copy programs.this programs take name of file and copy into the same folder with the same name concatenate it to a "copy_" word.this is a simple program but i would like to develop it's features.
there are some problems at this way.when you give a executable program name to this simple copy program , the new "copy_executablefile" can't run.for other files such as files with 'pdf' extension it has no problems and copied file (copy_pdfextensionfile) is exactly like the same original file.but in executable file i have a problem.after some check and compare between original file and copied file byte by byte using "Hex Editor" program i discovered that at the end of copied file one byte with 00H value is extra.after removing this extra byte using Hex Editor ,copied file runs successfully.but i can't find out why this extra byte appends into copy_file.what do you know about this prob?please help me.perhaps copying character by character is the reason.because a character is 4byte.what's the solution?
you can see this simple prog following.

//this prog tested in Ubuntu 10.10 with Gcc compiler and works correctly.
//begining of copy program.
cout<<"Enter file name:\n";
