Write a program that reads in the following data, all entered on one line with at least one space separating them: a) an integer

representing a month b) an integer representing the day of the month c) an integer representing a year 1. Check that the month is between 1 and 12. If it’s not print an error message. 2. Day cannot be 0 or less nor can it be more than 31 for all months. Print an error message if these conditions occur. If day is in the range of 0 and 31, you will still need to check other conditions as noted below in 4. 3. Year cannot be less than 1. Print an error message if that occurs. If any one of these three conditions occurs, only one error message should print and no further code should be executed. If everything is good so far, then continue as below: 4. Check that day is correct for the month. Remember the poem "30 days has September, April, June and November, All the rest have 31 except February which has 28 but in a leap year has 29"

Answer:

import java.util.Scanner;

public class DataConstraint {

public static void main(String[] args) {

System.out.print("Enter month, day, year separated by spaces :");

Scanner sc=new Scanner(System.in);

int M,D,Y;

M=sc.nextInt();

D=sc.nextInt();

Y=sc.nextInt();

if(1<=M && M<=12 && 1<=D && D<=31 && Y>=1)

{

if(M==4 || M==6 ||M==9 || M==11){

if(D==31) {

System.out.println("month "+M+" can not have more than 30 days");

System.exit(0);

}

}

else if(M==2)

{

if((Y%400==0) || (Y%4==0 && Y%100!=0)) {

if(D>=30) {

System.out.println("month "+M+" cannot have "+D+" days");

System.exit(0);

}

}

else {

if(D>=29) {

System.out.println(Y+" is not a leap year, "+D+" is invalid");

System.exit(0);

}

}

}

System.out.println(M+" "+D+" "+Y+" is a valid date");

}

else{

if(1>=M || M>=12) System.out.println(M+" is not a valid month");

if(1>=D || D>=31) System.out.println(D+" is not a valid date");

if(Y<1) System.out.println("year can not be negative");

}

}

}

Explanation:

  • Use a conditional statement to check the month is between 1 and 12.
  • Check that the date is between 1 and 31 and year must be positive value.
  • If no. of days are more than 29, then the year cannot be a leap year.

6.23 LAB: Convert to binary - functions Instructor note: This is a lab from a previous chapter that now requires the use of a fu
Kitty [74]

Answer:

The program in Python is as follows:

import math

def integer_to_reverse_binary(integer_value):

   remainder = ""

   while integer_value>=1:

       remainder+=str(integer_value % 2)

       integer_value=math.floor(integer_value/2)

   reverse_string(remainder)

def reverse_string(input_string):

   binaryOutput=""

   for i in range(len(input_string)-1,-1,-1):

       binaryOutput = binaryOutput + input_string[i]

   print(binaryOutput)

integer_value = int(input("Enter a Number : "))

integer_to_reverse_binary(integer_value)

Explanation:

This imports the math module

import math

This defines the integer_to_reverse_binary function

def integer_to_reverse_binary(integer_value):

This initializes the remainder to an empty string

   remainder = ""

This loop is repeated while the integer input is greater than or equal to 1

   while integer_value>=1:

This calculates the remainder after the integer value is divided by 2

       remainder+=str(integer_value % 2)

This gets the floor division of the integer input by 2

       integer_value=math.floor(integer_value/2)

This passes the remainder to the reverse_string function

   reverse_string(remainder)

The reverse_string function begins here

def reverse_string(input_string):

This initializes the binaryOutput to an empty string

   binaryOutput=""

This iterates through the input string i.e. the string of the remainders

   for i in range(len(input_string)-1,-1,-1):

This reverses the input string

       binaryOutput = binaryOutput + input_string[i]

This prints the binary output

   print(binaryOutput)

<u>The main begins here</u>

This gets input for integer_value

integer_value = int(input("Enter a Number : "))

This passes the integer value to the integer_to_reverse_binary function

integer_to_reverse_binary(integer_value)
