The program should concatenate the content of the n files separated by ' ' and write the result on the standard output and also into output.txt. Read the input files and write the output file using the binary mode. Use a char buffer of size 64 bytes and chunks of size 1 byte when reading and the same buffer with chunks of size 64 bytes (or less if the last write and file size is not a multiply of 64) when writing.
