cin

if-else

Following is the conversion code

code:

#include <iostream>

#include <cmath>

using namespace std;

int main()

{

    int num, binaryNumber,decimal;

    cout << "Enter a decimal number: ";

    cin >> num;

   

    decimal=num;

    

    int remainder, i = 1;

    while (num!=0)

    {

        remainder = num%2;

        num /= 2;

        binaryNumber += remainder*i;

        i *= 10;

    }

     

    cout << decimal << " in decimal = " << binaryNumber << " in binary" << endl ;

    return 0;

}

Output:

Enter a decimal number: 54

54 in decimal = 110110 in binary
