Program description: a c# app is to be created to produce morse code. the morse code assigns a series of dots and dashes to each letter of the alphabet, each digit, and a few special characters (such as period, comma, colon, and semicolon). in sound-oriented systems, the dot represents a short sound and the dash represents a long sound. separation between words is indicated by a space, or, quite simply, the absence of a dot or dash. in a sound-oriented system, a space is indicated by a short period of time during which no sound is transmitted. the international version of the morse code is stored in the data file morse.txt.
