Suppose I have to extract data from ranging latitude=6 N to 40 N and longitude=66 E to 100 E, what will be the code for this range of data for a nc file 'example.nc'

The answer depends on your example.nc file. Load the lat and lon variables with ncread and find the indices of lat and lon corresponding to your grid box of interest. Then use ncread with corresponding start and stride variables declared to load your gridded variable. Or you could load the whole variable and trim it down from there.
