hi namita ,
thanks for the reply , but my actual doubt was how could we create
basic data types like int , and incorporate them into the library and
use them again and again ,.....this was all started when i was
thinking about a 'smart int' (which is not a genuine idea, picked up
from the GSoc ideas for BoostC++), this type of variable can have
limits in which the value must lie !!
