Telégrafo

[Zeero]

E aí galera.

Esse aplicativo utiliza o speaker do gabinete para transmitir mensagens em código morse. O usuário escreve a mensagem, o programa converte para código morse e trasmite pelo speaker.

Note: se o speaker da sua máquina não estiver funcionando a mensagem não será transmitida.

Código:

#include <stdio.h>
#include <conio.h>
#include <dos.h>
#include <math.h>

char morse[600];
int c = 0;

int main()
{
    char msg[200];
    int i;

    void addDitDah(char);

    printf("Telegrafo C v1.0\n");
    printf("por Raphael Pina Viana\n\n");

    printf("Mensagem: ");

    for(i = 0; i < 200; i++)
    {
        printf("%c", msg[i] = getch());
        if(msg[i] == 13)
        {
            msg[i] = '';
            break;
        }
    }
    printf("\n");
