Hi All,

C follows procedural oriented approach and in procedural
oriented programmers are more focussed on functions rather
than data, how they write the program is more concerned
rather than security. But in object oriented programmer's
have given more priority to data than blocks.
Also procedural oriented terms difficult to understand ,but
object oriented meets real world existing system every thing
is considered as objects. I cannot write a program like
factorial but i can write a class called person...
This is main difference between c and c++.
