11-7 A Programming Example— Morse CodeMorse code, patented by Samuel F. B. Morse in 1837, Morse code, patented by Samuel F. B. Morse in 1837, is the language that was used to send messages by is the language that was used to send messages by telegraph from the middle of the nineteenth century telegraph from the middle of the nineteenth century until the advent of the modern telephone and today’s until the advent of the modern telephone and today’s computer controlled communications systems. In this computer controlled communications systems. In this section, we use a C program to convert English to section, we use a C program to convert English to Morse and Morse to English. Morse and Morse to English.
