Dado un número octal como entrada, la tarea es convertir ese número en un número binario.
Ejemplos:
Input : Octal = 345 Output : Binary = 011100101 Explanation : Equivalent binary value of 3: 011 Equivalent binary value of 4: 100 Equivalent binary value of 5: 101 Input : Octal = 120 Output : Binary = 001010000
Número octal : un número octal es un sistema de numeración posicional con una raíz o base de 8 y utiliza ocho símbolos distintos.
Número binario : Un número binario es un número expresado en el sistema numérico binario de base 2, que utiliza solo dos símbolos: 0 (cero) y 1 (uno).
Para convertir un número octal a binario, el equivalente binario de cada dígito del número octal se evalúa y se combina al final para obtener el número binario equivalente.
A continuación se muestra la implementación del enfoque anterior:
C++
// C++ program to convert
// Octal number to Binary
#include <iostream>

string binary = "";
while (octnum[i]) {
switch (octnum[i]) {
case '0':
binary += "000";
break;
case '1':
binary += "001";
break;
case '2':
binary += "010";
break;
case '3':
