Answer:
See explaination
Explanation:
class Counter:
def getValue(self):
return self._value
def undo(self):
if self._value > 0:
self._value = self._value - 1;
def click(self):
self._value= self._value + 1
def reset(self):
self._value= 0
tally= Counter()
tally.reset()
tally.click()
tally.click()
result = tally.getValue()
print("Value:", result)
tally.click()
result = tally.getValue()
print("Value:", result)
tally.undo()
tally.undo()
result = tally.getValue()
print("Value:", result)
tally.undo()
tally.undo()
result = tally.getValue()
print("Value:", result)
The following code will program that prompts the user to enter the num- ber of hours a car is parked at the airport and outputs the parking fee.
<u>Explanation:</u>
Code:
#include<iostream>
using namespace std;
int main()
{
float hours;
cout <<"Enter number of hours a car parked at the airport: "; // prompt the user to enter hours.
cin >> hours ; // strong the hours
if (hours > = 0 && hours < =3 ) // if 0 < = h < = 3
cout << "Parking fee: 5"; //printing parking fee is 5.
else if (hours > 3 && hours < = 9)//if 3 < h < = 9
cout<<"Parking fee: "<<6*int(hours);//converting float value to int the multiplying with 6 then printing fee.
else//if 9 < h < = 24
cout<< "Parking fee: 60";// printing parking fee 60.
return 0;
}
B. Because the computer can rearrange itself when it is in a phase of conversion
B. A data source is the answer. Hope it’s right.
Answer:
- policy_num = int(input("Enter policy number: "))
- lastName = input("Enter last name: ")
- firstName = input("Enter first name: ")
- premiumDate = input("Enter premius due date (mm/dd/yyyy): ")
- numAcc = int(input("Enter number of driver accident in the past three years: "))
-
- if(policy_num <1000 or policy_num > 9999):
- policy_num = 0
-
- dateComp = premiumDate.split("/")
- month = int(dateComp[0])
- day = int(dateComp[1])
- year = int(dateComp[2])
-
- if(month < 1 or month > 12):
- month = 0
- day = 0
- year = 0
- else:
- if(month == 1 or month == 3 or month == 5 or month == 7 or month == 8 or month == 10 or month == 12):
- if(day < 1 or day > 31):
- month = 0
- day = 0
- year = 0
- elif(month == 4 or month == 6 or month == 9 or month == 11):
- if(day <1 or day > 30):
- month = 0
- day = 0
- year = 0
- elif(month == 2):
- if(day < 1 or day > 29):
- month = 0
- day = 0
- year = 0
-
- print("Policy number: " + str(policy_num))
- print("Last name: " + lastName)
- print("First name: " + firstName)
- print("Premium Date: " + str(month) + "/" + str(day) + "/" + str(year))
- print("Number of driver accidentin the last three years: " + str(numAcc))
Explanation:
The solution code is written in Python 3.
Firstly use input function to prompt user to enter all the necessary insurance policy data (Line 1 - 5).
Next create an if statement to validate the input policy number. If the policy number is not within the range of 1000 - 9999, set the policy number to zero (Line 7 -8).
Next, split the input premium date into month, day and year (Line 10 -13). It is followed by checking the month if it is between 1 - 12. If not, set the month, day and year to zero (Line 15 - 18). Otherwise the program will proceed to validate the month based on the maximum and minimum number of days for a particular month (Line 20 - 34). If the day is out of range, set month, day and year to zero.
Lastly, use print function to display the policy data (Line 36 - 40).
