Labels: text | screenshot | font OCR: If we assume that we have typed the command line cnt_letters chapter1 datal to execute this program, then "argv[0]" points to the string "cnt letters", "argy[1]" points to the string "chapter1", and "argy[2]" points to the string "datal". Thus, the file "chapter1" is opened for reading with file pointer "ifp" referring to it, and the file "datal" is opened for writing with file pointer "ofp" referring to it.
