Dado un número decimal como entrada, necesitamos escribir un programa para convertir el número decimal dado en un número binario equivalente.
Ejemplos:
C++
// C++ program to convert a decimal
// number to binary number
#include <iostream>
using namespace std;
// function to convert decimal to binary
void decToBinary(int n)
{
// array to store binary number
int binaryNum[32];
// counter for binary array
int i = 0;
while (n > 0) {
// storing remainder in binary array
binaryNum[i] = n % 2;
n = n / 2;
i++;
}
// printing binary array in reverse order
for (int j = i - 1; j >= 0; j--)
cout << binaryNum[j];
}
// Driver program to test above function
int main()
{
int n = 17;
decToBinary(n);
return 0;
}
C
// C Code to convert Decimal number into Binary
#include <stdio.h>
void decToBinary(int n)
{
// array to store binary number
int binaryNum[32];
// counter for binary array
int i = 0;
while (n > 0) {
// storing remainder in binary array
binaryNum[i] = n % 2;
n = n / 2;
i++;
}
// printing binary array in reverse order
for (int j = i - 1; j >= 0; j--)
printf("%d", binaryNum[j]);
}
// Driver program to test above function
int main()
{
int n = 17;
decToBinary(n);
return 0;
}
Java
// Java program to convert a decimal
// number to binary number
import java.io.*;
class GFG {
// function to convert decimal to binary
static void decToBinary(int n)
{
// array to store binary number
int[] binaryNum = new int[32];
// counter for binary array
int i = 0;
while (n > 0) {
// storing remainder in binary array
binaryNum[i] = n % 2;
n = n / 2;
i++;
}
// printing binary array in reverse order
for (int j = i - 1; j >= 0; j--)
System.out.print(binaryNum[j]);
}
// driver program
public static void main(String[] args)
{
int n = 17;
decToBinary(n);
}
