    // The JSON response to be parsed looks like this:
    // {
    //   "LifeAmount": 513.85,
    //   "LifeResidualAmount": 123.38,
    //   "CriticalIllnessAmount": 0,
    //   "CriticalIllnessResidualAmount": 0,
    //   "DisabilityAmount": 881.70,
    //   "PolicyFee": 0.00,
    //   "PolicyFeeSecondary": 0,
    //   "PolicyFeeHidden": 50.00,
    //   "PolicyFeeHiddenSecondary": 0
    // }

    // We can get the floating point numbers as strings.  Then convert to double
    // using the appropriate string-to-double conversion for your programming language.
    // For example, in C++ use atof.  In C# use Convert.ToDouble.

    wprintf(L"LifeAmount = %s\n",lifeAmount);
    wprintf(L"LifeResidualAmount = %s\n",lifeResidualAmount);
