Transcription: These two code samples show two equivalent methods of copying data from one file to another by reading the input file one character at a time and writing each character to the output file. In the code on the left, the GET function is used to read single characters from source and the PUT function is used to write them to DEST. In the code on the right, the input operator is used to extract character values from the source and the output operator is used to insert them into DEST.
