Answer:
following are the program to the given question:
Program:
x = 0#defining an integer variable that holds a value
if x < 0:#defining if that checks x less than 0
print("This number ", x, " is negative.")#print value with the message
else:#defining else block
if x > 0:#defining if that checks x value greater than 0
print(x, " is positive")#print value with message
else:#defining else block
print(x, " is 0")#print value with message
if x < 0:#defining another if that checks x less than 0
print("This number ", x, " is negative.")
elif (x > 0):#defining elif block that check x value greater than 0
print(x, " is positive")#print value with message
else:#defining else block
print(x, " is 0")#print value with message
Output:
Please find the attachment file.
Explanation:
In this code, an x variable is defined which holds a value that is "0", in the next step nested conditional statement has used that checks the x variable value and uses the print method that compares the value and prints its value with the message.
In another conditional statement, it uses if that checks x value less than 0 and print value with the negative message.
In the elif block, it checks x value that is greater than 0 and prints the value with the positive message, and in the else block it will print the message that is 0.

Explanation:
The following code was written in Java it creates a switch statement for all the month values in order to turn them from Strings into integer values. Then it reads every line of input places them into an array of dates if they are the correct input format, and loops through the array changing every date into the correct output format.Ouput can be seen in the attached picture below.
import java.util.ArrayList;
import java.util.Scanner;
class Brainly {
public static int intForMonth(String monthString) {
int monthValue;
switch (monthString) {
case "January": monthValue = 1;
break;
case "February": monthValue = 2;
break;
case "March": monthValue = 3;
break;
case "April": monthValue = 4;
break;
case "May": monthValue = 5;
break;
case "June": monthValue = 6;
break;
case "July": monthValue = 7;
break;
case "August": monthValue = 8;
break;
case "September": monthValue = 9;
break;
case "October": monthValue = 10;
break;
case "November": monthValue = 11;
break;
case "December": monthValue = 12;
break;
default: monthValue = 00;
}
return monthValue;
}
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
ArrayList<String> dates = new ArrayList<>();
String date;
String month;
String day;
String year;
int i = 0;
while (true) {
date = scnr.nextLine();
if (date.equals("-1")) {
break;
}
dates.add(date);
}
for (i = 0; i < dates.size(); i++) {
try {
month = dates.get(i).substring(0, dates.get(i).indexOf(" "));
day = dates.get(i).substring(dates.get(i).indexOf(" ") + 1, dates.get(i).indexOf(","));
year = dates.get(i).substring(dates.get(i).indexOf(",") + 2, dates.get(i).length());
System.out.println(intForMonth(month) + "/" + day + "/" + year);
} catch (Exception e) {}
}
}
}
