I am using the API TranslateColors() to convert RGB to CYMK. I could convert it.

In the above sample RGB value is left shifted by 8 and passed to the above function. And the result, CYMK is right shifted by 8.

As I know CYMK values vary from 0 to 1. But the result are more than 1.

Can any one tell me how to get the CYMK values in 0-1.

RGB values are between the range 0-255
to get this range between 0-1
you will need to do:

ic[0].rgb.red = (255.0 / 255.0) << 8 ;
ic[0].rgb.green = (0 / 255.0);
ic[0].rgb.blue = (0 / 255.0);

basically

value = value / max_range_of_value;

make sure the variables used are floats or decimals (or anything that supports decimals).
