1>c is an procedural language and c++ is an object oriented.
2>c uses a TOP DOWN approach and c++ BOTTOM UP.
3>c++ introduces the idea of Data hiding using class..shere
in c there is no such facility for that purpose
4>c++ introduce the concept of the message passing with that
objects can communicate.
5>c++ has the inheritence, using it we can reuse our code.
6>Using polymorphism of c++ we can achieve the overloading
of operator and functions, but it is not possible in c.

there may be more difference on this but these are the main..

write a program to enter a string like"sunil is a good boy and seeking for a job" not more than 10 characters including space in one line,rest characters should b in other line.if the next line starts from in between the previous word,then print whole word to next line.
