Morse Code for C

sibyl03 · #1 12-Oct-2004, 20:42

Hi All,
i need to input ("English Letter") and print the output as Morse Code.
Rather new to C program. SO i don't know about strings etc...
But i do know that it involves char, put char(), print char () and probably even switches.
Can someone give me an idea how to begin doing?

thanks!

The way I's do this is with character arrays.
Define a character array inbuf for your input of "English Letter".
Define a 2 dimensional array for the Morse Code:

CPP / C++ / C Code:

char inbuf[128];
char morse[256][10] = 
{    0,0,0,0 ... (32 times for non printing characters)
      "  ",         // space
      ".-..-.  ",   // quotes
      "",          // #
      "",          // $
      etc
      "-----  ", // 0
      ".----  ", // 1
      "..---  ", // 2
      "...--  ", // 3
      "....-  ", // 4
      ".....  ", // 5
and so on

The 256 is for each ASCII character. Look up each character's value in an ASCII chart
The 10 is for the characters needed for each morse code symbol.

Read a sentence into inbuf and look at each character. Use that character as an index into the morse array to output the morse code for the character.
