    two variables?

    I need to test the following code fragment for the variable num. For me to completely test all branches, would I use 2 values of num?

    How many values of the variable num must by used to completely test all branches of the following code fragment?
    if (num > 0 )
    if (value < 25 )
    {
    value = 10 * num;
    if ( num < 12 )
    value = value / 10;
    } / * if sum * /
    else value = 20 * num;
    else value = 30 * num;



    Thanks!
