binary

hi!
I need to write a progam that will convert a number to binary.
Example
user enters number between 0 and 15
output is the value of the number returned to screen
and then the output in binary returned to the screen

thank you!

Here's one solution -

#include <iostream>
#include <bitset>

using namespace std;

Code:

---

#include <iostream>
#include <bitset>

using namespace std;

int main()
{

    int i =0;

    do
    {
        cin >>i;
    }while (i<0 || i>15);

    //need four bits to represent 0-15

    bitset <4> j = i;
    cout << i << " = " << j << endl;


    return 0;
}

However, if this is a homework assignment then I doubt that this will be the answer you're looking for. Let's see what you've done so far.
