Set a linkelist collection −var list = new LinkedList();Now, add elements −list.AddLast("One"); list.AddLast("Two"); list.AddLast("Four");Now, let us add new elements in the already created LinkedList −LinkedListNode node = list.Find("Four"); list.AddBefore(node, "Three"); list.AddAfter(node, "Five");Let us now see how to traverse through the nodes in a Singly Linked List −Exampleusing System; using System.Collections.Generic; ...

In the electromagnetic spectrum, waves within the frequencies 1GHz to 300GHz are called microwaves.Features of MicrowavesMicrowaves travel in straight lines, and so the transmitter and receiver stations should be accurately aligned to each other.Microwave propagation is line – of – sight propagation. So, towers hoisting the stations should be placed ... Read More

A communication satellite is an artificial satellite that acts as a large repeater in the sky. It receives signals from the source transmitter, amplifies using transponders, and relays them to the receiver. Thus, it creates a communication channel between locations of the earth that would not have been able to ... Read More

Let us first set an array of 5 characters −char[] ch = new char[15]; ch[0] = 'T'; ch[1] = 'r'; ch[2] = 'i'; ch[3] = 'c'; ch[4] = 'k';Now convert them into a string −string str = new string(ch);Here is the complete code −ExampleUsing System; class Program {    static ... Read More
