Finds INTEGRAL of f(x) by Trapezoidal and Simpson method Simultaneously
TRAPEZOIDAL RULE :-
Integral of F(x) in between the limits a and b is given by
=(h/2)*(y+2(y+y+y+..y)+y)
where y=F(x),
x=x+h,
h=(b-a)/n.

Networking is all about transmitting messages from one node to another. The simplest example can be to transmit "Hello World" from one computer to another. Socket programming in C/C++ has already been covered. Today we will see how to check if the transmitted data has any errors.
There are many...

I thought of sharing the code snippet. It just does the basic operations like inserting a node at the end of the linked list and deletion of any particular node in the linked list. The deletion of a node in linked list is based on the data of the node and not on the index at which data is located....
