O iniciante em eletrônica esta sempre em busca de programas para ajudá-lo em cálculos de resistores.
Este programa tem uma interface agradável com menus inteligentes e poderá ajuda-lo
nos seus cálculos de resistência. O código foi compilado no MinGw mais os programadores experientes
poderá compilá-lo em qualquer compilador e ainda fazer alterações para torná-lo mais adequado as suas necessidades.

Veja o Código abaixo:

#include <stdio.h>

#include <conio2.h>

#include <time.h>
