integer to binary code example

Example 1: integer to binary java

Integer.toString(100,8) // prints 144 --octal representation

Integer.toString(100,2) // prints 1100100 --binary representation

Integer.toString(100,16) //prints 64 --Hex representation

Example 2: decimal to binary

//Java Solution for Decimal To Binary Conversion

import java.util.*;
public class DecimalToBinary {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner sc = new Scanner(System.in);
		int dec = sc.nextInt();
		StringBuffer sb = new StringBuffer();
		while(dec!=0)
		{
			sb.append(dec%2);
			dec=dec/2;
		}
		System.out.println(sb.reverse());
		
	}

}

Example 3: decimal to binary

# Python program to convert decimal to binary
   
# Function to convert Decimal number
# to Binary number
def decimalToBinary(n):
    return bin(n).replace("0b", "")
   
# Driver code
if __name__ == '__main__':
    print(decimalToBinary(8))
    print(decimalToBinary(18))
    print(decimalToBinary(7))

Example 4: decimal to binary

std::string binary = std::bitset<8>(n).to_string();

Example 5: decimal to binary

#include <iostream>
#include <stdlib.h>

int main ()
{
    int i;
    char buffer [33];
    printf ("Enter a number: ");
    scanf ("%d",&i);
    itoa (i,buffer,10);
    printf ("decimal: %s\n",buffer);
    itoa (i,buffer,16);
    printf ("hexadecimal: %s\n",buffer);
    itoa (i,buffer,2);
    printf ("binary: %s\n",buffer);
    return 0;
}
