18.1.10.write a decimal integer as a binary number

#include <bitset>

#include <iostream>

#include <limits>



using namespace std;



int main( )

{

   // write a decimal integer as a binary number

   int num = 100;

   cout  << "\n\nDecimal number: " << num << "\tBinary equivalent: " << bitset<8>(num) << endl;

}
