B, Parallel ports are faster than serial ports.

A parallel port can move a set of 8 bits at a time on eight different wires, it uses a 25 pin connector, called a DB-25 connector, whereas a serial port only has a DB-9 connector.

Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending whe

dalvyx [7]

Answer:

string=""

while string not in {"Quit","quit","q"}:

string=input("Enter line to be reversed") #line of text will be entered

if string!="Quit" and string!="quit" and string!="q": #If quit is not entered

print("Reverse of line is : ")

print(string[::-1])

OUTPUT :

Enter line to be reversedThis code is in python language

Reverse of line is :

egaugnal nohtyp ni si edoc sihT

Enter line to be reversedHello world

Reverse of line is :

dlrow olleH

Enter line to be reversedquit

Explanation:In the above program, First a while loop is executed and checked if line of text is not 'quit', 'Quit' or 'q'. If condition is true, then loop is executed and in python any string or list can be traversed from end if step is given -1. Similarly line of text is accessed from the last element. If quit is entered, then the program will be broken out of the loop.

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use

jeyben [28]

Question:

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use the gas equation PV = nRT, where P is pressure in Pascals, V is volume in cubic meters, n is number of moles, R is the gas constant 8.3144621 ( J / (mol*K)), and T is temperature in Kelvin.

Answer:

This solution is implemented in C++

double compute_gas_volume(double P, double T, double n){

double V = 8.3144621 * n * T/P;

return V;

}

Explanation:

This line defines the function, along with three parameters

double compute_gas_volume(double P, double T, double n){

This calculates the volume

double V = 8.3144621 * n * T/P;

This returns the calculated volume

return V;

}

To call the function from the main, use:

<em />

<em>Where P, T and n are double variables and they must have been initialized</em>

Write code to take a String input from the user, then print the first and last letters of the string on one line. Sample run: En

Ainat [17]

<h2>Answer:</h2>

//import the Scanner class to allow for user input

import java.util.Scanner;

//Begin class definition

public class FirstAndLast{

//Begin the main method

public static void main(String []args){

//****create an object of the Scanner class.

//Call the object 'input' to receive user's input

//from the console.

Scanner input = new Scanner(System.in);

//****create a prompt to tell the user what to do.

System.out.println("Enter the string");

//****receive the user's input

//And store it in a String variable called 'str'

String str = input.next();

//****get and print the first character.

//substring(0, 1) - means get all the characters starting

//from the lower bound (index 0) up to, but not including the upper

//bound(index 1).

//That technically means the first character.

System.out.print(str.substring(0,1));

//****get and print the last character

//1. str.length() will return the number of character in the string 'str'.

//This is also the length of the string

//2. substring(str.length() - 1) - means get all the characters starting

// from index that is one less than the length of the string to the last

// index (since an upper bound is not specified).

// This technically means the last character.

System.out.print(str.substring(str.length()-1));

} // end of main method

} //end of class definition

<h2>Explanation:</h2>

The code has been written in Java and it contains comments explaining important parts of the code. Kindly go through the comments.
