Here's the C code implementation. It is working, but with a wierd output:

Code:

#include<stdio.h>
#include<string.h>
#include<ctype.h>

struct morse {
        char letter;
        char morseCode[6];
};

int main(int argc, char *argv[]) {
        struct morse morse[36];
        char input;

        morse[0].letter='0';
        strcpy(morse[0].morseCode,"-----");
        morse[1].letter='1';
        strcpy(morse[1].morseCode,".----");
        morse[2].letter='2';
        strcpy(morse[2].morseCode,"..---");
        morse[3].letter='3';
        strcpy(morse[3].morseCode,"...--");
        morse[4].letter='4';
        strcpy(morse[4].morseCode,"....-");
        morse[5].letter='5';
        strcpy(morse[5].morseCode,".....");
        morse[6].letter='6';
        strcpy(morse[6].morseCode,"-....");
        morse[7].letter='7';
        strcpy(morse[7].morseCode,"--...");
        morse[8].letter='8';
        strcpy(morse[8].morseCode,"---..");
        morse[9].letter='9';
        strcpy(morse[9].morseCode,"----.");
        morse[10].letter='A';
        strcpy(morse[10].morseCode,".-");
        morse[11].letter='B';
        strcpy(morse[11].morseCode,"-...");
        morse[12].letter='C';
        strcpy(morse[12].morseCode,"-.-.");
        morse[13].letter='D';
        strcpy(morse[13].morseCode,"-..");
        morse[14].letter='E';
        strcpy(morse[14].morseCode,".");
        morse[15].letter='F';
        strcpy(morse[15].morseCode,"..-.");
        morse[16].letter='G';
        strcpy(morse[16].morseCode,"--.");
        morse[17].letter='H';
        strcpy(morse[17].morseCode,"....");
        morse[18].letter='I';
        strcpy(morse[18].morseCode,"..");
        morse[19].letter='J';
        strcpy(morse[19].morseCode,".---");
        morse[20].letter='K';
        strcpy(morse[20].morseCode,"-.-");
        morse[21].letter='L';
        strcpy(morse[21].morseCode,".-..");
        morse[22].letter='M';
        strcpy(morse[22].morseCode,"--");
        morse[23].letter='N';
        strcpy(morse[23].morseCode,"-.");
        morse[24].letter='O';
        strcpy(morse[24].morseCode,"---");
        morse[25].letter='P';
        strcpy(morse[25].morseCode,".--.");
        morse[26].letter='Q';
        strcpy(morse[26].morseCode,"--.-");
        morse[27].letter='R';
        strcpy(morse[27].morseCode,".-.");
        morse[28].letter='S';
        strcpy(morse[28].morseCode,"...");
        morse[29].letter='T';
        strcpy(morse[29].morseCode,"-");
        morse[30].letter='U';
        strcpy(morse[30].morseCode,"..-");
        morse[31].letter='V';
        strcpy(morse[31].morseCode,"...-");
        morse[32].letter='W';
        strcpy(morse[32].morseCode,".--");
        morse[33].letter='X';
        strcpy(morse[33].morseCode,"-..-");
        morse[34].letter='Y';
        strcpy(morse[34].morseCode,"-.--");
        morse[35].letter='Z';
        strcpy(morse[35].morseCode,"--..");

        while((input=fgetc(stdin))!=EOF) {
                if(input=='\n') fprintf(stdout,"\n");
                if(input==' ') {
                        fprintf(stdout,"   ");
                }
                if(input>47&&input<58) {
                        fprintf(stdout,"%s ",morse[input-48].morseCode);
                        continue;
                }
                input=toupper(input);
                fprintf(stdout,"%s ",morse[input-55].morseCode);
        }

}

The letter in the struct is not used because I am manipulating the array index, but if you try to add symbols, it may be necessary to actually run through the entire array every time and compare the input value with the letter and print the corresponding morse code value. And I can't understand the output that I'm getting either.

Code:

# ./a.out < test
- .... .. ...    ��� .. ...    ��� .-    ��� - . ... -    ��� ..-. .. .-.. .    ��� - . ... - .. -. --.    ��� ..-. --- .-.    ��� -- --- .-. ... .    ��� -.-. --- -.. .    ��� - .... .- -    ��� .. ...    ��� -- --- .-. ... .    ��� .- -. -..    ��� -. --- -    ��� -- --- .-. --.. .

Why are those symbols popping up after every " " that is encountered?
