Question

I am looking for some brief explanations on how the below program or code works.Thanks

public void Convert( int iNum )
{
    int m = 0;
    if (iNum == 1 )
        System.out.print( iNum );
    else
    {
        m = iNum % 2;
        Convert(iNum/2);
        System.out.print(m);
    }
}

Answer 1

This program tries to convert a decimal number to binary using recursion. Lets take an example:

Decimal 5 -> Binary 101

Convert(5):
m = 5 %2 -> 1
   Convert(2):
       m -> 2%2 -> 0
       Convert(1)
          The first if is true: -> 1

Output: 101
