Answer:
Electromagnetic interference and noise from the transmitting or receiving device.
Explanation:
Communication involves four processes, they are; encoding, sending, decoding, and feedback. A message, during this process of communication, can be altered, this is known as noise.
Telecommunication is simply communication between long distances. The effect of noise is more pronounced and can be noticed by listeners. These noises are produced by the transmitter and electromagnetic signals or waves of other transmitting devices.
Answer: Option C is correct
Explanation:
Option C is correct
A complete program with the method ShowCar:
import java.util.Scanner; // header file
public class ShowChar
{
public static void main(String[] args)
{
String lnOfText;
int i;
Scanner input = new Scanner(System.in);
System.out.print("Enter a line of text:");
lnOfText = input.nextLine();
System.out.print(" Enter your index: ");
i = input.nextInt();
show_Char(lnOfText,i);
}
public static void show_Char(String str_a, int i)
{
System.out.print(str_a.charAt(i));
}
}
In this program, both the inputs ie. a sentence or line of text as well as the index position is obtained. A method is written to find the string at that particular position. Finally the method prints that character at the particular index.
