Answer: You can see the truth table in the image.

Explanation:We can do this question by using truth table.

As we can see in the truth table that there is no effect on the output of the expression by c if a and b both are false then the output is false and if any of them is True or both of them are True then the result is True.

Write a program that converts a time in 12-hour format to 24-hour format. The program will prompt the user to enter a time in HH

podryga [215]

Answer:

This program is written in Python

inputtime = input("HH:MM:SS AM/PM: ")

splittime = inputtime.split(":")

secondAM = splittime[2].split()

if secondAM[1] == "AM":

print(splittime[0]+":"+splittime[1]+":"+secondAM[0])

elif secondAM[1] == "PM":

HH = int(splittime[0])

HH = HH + 12

print(str(HH)+":"+splittime[1]+":"+secondAM[0])

Explanation:

This line prompts user for input

inputtime = input("HH:MM:SS AM/PM: ")

This line splits the input string to HH, MM and "SS AM/PM"

splittime = inputtime.split(":")

This line splits "SS AM/PM" to SS and AM/PM

secondAM = splittime[2].split()

This line checks if time is AM

if secondAM[1] == "AM":

This line prints the equivalent time

print(splittime[0]+":"+splittime[1]+":"+secondAM[0])

Else;

elif secondAM[1] == "PM":

The equivalent 24 hour is calculated

HH = int(splittime[0]) + 12

This line prints the equivalent time

print(str(HH)+":"+splittime[1]+":"+secondAM[0])

(1) Prompt the user to enter two words and a number, storing each into separate variables. Then, output those three values on a

Sergeu [11.5K]

Answer:

import java.util.Scanner;

public class num3 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter Favorite color");

String word1 = in.next();

System.out.println("Enter Pet's name");

String word2 = in.next();

System.out.println("Enter a number");

int num = in.nextInt();

//Point One

System.out.println("You entered: "+word1+" "+word2+

" "+num);

//Point Two

String passwordOne = word1+"_"+word2;

String passwordTwo = num+word1+num;

System.out.println("First password: "+passwordOne);

System.out.println("Second password: "+passwordTwo);

//Point Three

int len_passwrdOne = passwordOne.length();

int len_passwrdTwo = passwordTwo.length();

System.out.println("Number of characters in "+passwordOne+" :" +

" "+len_passwrdOne);

System.out.println("Number of characters in "+passwordTwo+" :" +

" "+len_passwrdTwo);

}

Explanation:

This question is solved using java programming language
The scanner class is used to receive the three variables (Two string and one integer)
Once the values have been received and stored in the respective variables (word1, word2 and num), Use different string concatenation to get the desired output as required by the question.
String concatenation in Java is acheived with the plus (+) operator.
