1.16 LAB: Input and formatted output: House real estate summary Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12 (Note: Output directly. Do not store in a variable.).
Ex: If the input is:
200000 210000
the output is:
This house is $200000. The change is $-10000 since last month.
The estimated monthly mortgage is $850.0.
Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming.
import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int currentPrice;
int lastMonthsPrice;
currentPrice = scnr.nextInt();
lastMonthsPrice = scnr.nextInt();
/* Type your code here. */
}
Answer:
Please find the complete code and the output in the attachement.
Explanation:
In the code, a class "LabProgram" is defined, and inside the main method two integer variable "currentPrice and lastMonthsPrice" is defined that uses the scanner class object is used for a user input value, and in the next step, two print method is declared that print the calculate of the integer variable.
The program is an illustration of output formats in Java
The statements that complete the program are:
System.out.printf("This house is $%d. The change is $%d since last month.\n",currentPrice,(currentPrice - lastMonthsPrice));System.out.printf("The estimated monthly mortgage is $%.1f.\n",(currentPrice * 0.051)/12);To format outputs in Java programming language, we make use of the printf statement, followed by the string literal that formats the required output
Take for instance:
To output a float value to 2 decimal place, we make use of the literal "%.2f"

Assuming dataFile is an ofstream object associated with a disk file named payroll.dat, which of the following statements would write the value of the salary variable to the file
A) cout <
B) ofstream
C) dataFile << salary;
D) payroll.dat <
Answer:
dataFile << salary;
Explanation:
To write salary to a file (payroll.dat) using ofstream, you make use of the following instruction:
ofstream dataFile;
myfile.open ("payroll.dat");
myfile <<salary;
myfile.close();
This line creates an instance of ofstream
ofstream dataFile;
This line opens the file payroll.dat
myfile.open ("payroll.dat");
This is where the exact instruction in the question is done. This writes the value of salary to payroll.dat
myfile <<salary;
This closes the opened file
myfile.close();

for(var i=0; i < copyNums.length; i++){
if(copyNums[i] == 1){
insertItem(copyNums,i,"hello");
}
}
This code will create an infinite loop. Why does it create an infinite loop?
Answer:
Explanation:
This code creates an infinite loop because it is detecting that the first value of copyNums is 1, therefore it runs the insertItem code. This code then adds the value "hello" to the array in position i which would be 0. Then moves to the next value of the array, but since the element "hello" pushed the value 1 to the next index then the code just repeats itself with the same value of 1. This continues to happen because every time the value "hello" is added it simply pushes the 1 to the next index and repeats the same code.
Answer:
[tex]var nums = [1,1, 2, 3, 5, 8, 13, 21];
var copyNums = [1,1, 2, 3, 5, 8, 13, 21];

Write a class called Person that has two data members - the person's name and age. It should have an init method that takes two values and uses them to initialize the data members.Write a separate function (not part of the Person class) called std_dev that takes as a parameter a list of Person objects (only one parameter: person_list) and returns the standard deviation of all their ages (the population standard deviation that uses a denominator of N, not the sample standard deviation, which uses a different denominator).
Answer:
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
def std_dev(person_list):
average = 0
for person in person_list:
average += person.age
average /= len(person_list)
total = 0
for person in person_list:
total += (person.age - average) ** 2
return (total / (len(person_list) )) ** 0.5
Explanation:
The class "Person" is a python program class defined to hold data of a person (name and age). The std_dev function accepts a list of Person class instances as an argument and returns the calculated standard deviation of the population.

/* missing precondition */
public String getChar(String str, int n) {
return str.substring(n, n 1); }
Write down the most appropriate precondition for the method so that it does not throw an exception.
Answer:
An appropriate precondition is:
0 <= n && n <= str.length() - 1
Explanation:
Required:
Write down an appropriate pre-condition for the program
From the question, we understand that the method accepts two parameters:
str -> A string value
n -> An integer value which represents the index of character to return from the string str
It should be noted that:
n must be within the range of 0 and str.length()-1
Take for instance:
str = "ABCDE";
n must be within the range 0 to 4 (inclusive) in order not to raise an exception. This is so because the string index starts at 0 and stops at 1 less than the length of the string.
Hence, the precondition can be written as:
0 <= n && n <= str.length() - 1
Which means: n = 0 to length - 1
Consider the following method, inCommon, which takes two Integer ArrayList parameters. The method returns true if the same integer value appears in both lists at least one time, and false otherwise.
public static boolean inCommon(ArrayList a, ArrayList b)
{

{
for (int j = 0; j < b.size(); j++) // Line 5
{
if (a.get(i).equals(b.get(j)))
{
return true;
}
}
}
return false;
}
Which of the following best explains the impact to the inCommon method when line 5 is replaced by for (int j = b.size() - 1; j > 0; j--) ?
A. The change has no impact on the behavior of the method.
B. After the change, the method will never check the first element in list b.
C. After the change, the method will never check the last element in list b.
D. After the change, the method will never check the first and the last elements in list b.
E. The change will cause the method to throw an IndexOutOfBounds exception.
Answer:
The answer is "Option b".
Explanation:
In the given code, a static method "inCommon" is declared, that accepts two array lists in its parameter, and inside the method two for loop is used, in which a conditional statement used, that checks element of array list a is equal to the element of array list b. If the condition is true it will return the value true, and if the condition is not true, it will return a false value. In this, the second loop is not used because j>0 so will never check the element of the first element.

In this program we are going to practice using the Math class by computing some important values on the unit circle. Starting at 0 and going up by
PI/4 radians (or 45 degrees), print out information of the format below.
Radians: (cos, sin)
0.0: 1.0, 0.0
0.79: 0.7, 0.71
1.57: 0.0, 1.0
2.36: -0.71, 0.7
3.14: -1.0, 0.0
3.93: -0.7, -0.71
4.71: 0.0, -1.0
5.5: 0.71, -0.71
Hints:
You’ll need to use the Math.sin, Math.cos methods
and the Math.PI constant!
You’ll also need to loop from 0 to 2*PI
You can round a decimal to 2 decimal places by multiplying by 100, rounding to the nearest int, and then dividing by 100. Here’s an example:
double value = 0.431675;
value = value * 100; // 43.1675
value = Math.round(value) // 43.0
value = value / 100.0; // 0.43
// Or put it all on one line:
value = Math.round(value * 100) / 100.0;
Answer:
The program in Java is:
import java.lang.*;
public class MyClass {
public static void main(String args[]) {
for(int i= 0;i<360;i+=45){
double angle = Math.round(Math.toRadians(i)*100.0)/100.0;
double cosX = Math.round(Math.cos(angle)*100.0)/100.0;
double sinX = Math.round(Math.sin(angle)*100.0)/100.0;
System.out.println(angle+": "+cosX +" "+ sinX);
}
}
}
Explanation:
This line iterates through the angles from 0 to 360 or 0 to 2*Pi
for(int i= 0;i<360;i+=45){
This calculates the angle to radians
double angle = Math.round(Math.toRadians(i)*100.0)/100.0;
This calculats the cosine of the angle rounded to 2 decimal place
double cosX = Math.round(Math.cos(angle)*100.0)/100.0;
This calculats the sine of the angle rounded to 2 decimal place
double sinX = Math.round(Math.sin(angle)*100.0)/100.0;
This prints the required output
System.out.println(angle+": "+cosX +" "+ sinX);
}

A drink costs 2 dollars. A taco costs 3 dollars. Given the number of each, compute total cost and assign totalCost with the result. Ex: 4 drinks and 6 tacos yields totalCost of 26.

int main() {
int numDrinks = 0;
int numTacos = 0;
int totalCost = 0;
numDrinks = 4;
numTacos = 6;
/* Your solution goes here */
totalCost = (2 * numDrinks) + (3 * numTacos);
cout << "Total cost: " << totalCost << endl;
return 0;
}
Answer:
See Explanation
Explanation:
The question has been answered; however, the program is not dynamic enough because the output will always be 26.
To make it dynamic, replace the following lines of code:
numDrinks = 4;
numTacos = 6;
with:
cout<<"Number of drinks: ";
cin>>numDrinks;
cout<<"Number of Tacos: ";
cin>>numTacos;
The above lines of code will let the user input different values for numDrinks and numTacos each time the program is executed.
Computing the total cost using code can be represented as follows:
def total_cost(no_of_drinks, no_of_talcos):
totalCost = 2*no_of_drinks + 3*no_of_talcos
return totalCost
print(total_cost(4, 6))
Python code explanation:A function named total_cost is declared and it accept the parameters no_of_drinks and no_of_talcos.
The totalCost is used to store the result of the cost of the total drinks and tacos bought in dollars.
Then, we return the totalCost.
Finally, we use the print statement to call the function with its required parameters.

Write a method named numUnique that accepts a sorted array of integers as a parameter and that returns the number of unique values in the array. The array is guaranteed to be in sorted order, which means that duplicates will be grouped together. For example, if a variable called list stores the following values: int[] list
Answer:
The method in Java is as follows:
public static int numUnique(int list[]) {
int unique = 1;
for (int i = 1; i < list.length; i++) {
int j = 0;
for (j = 0; j < i; j++) {
if (list[i] == list[j])
break;
}
if (i == j)
unique++;
}
return unique;
}
Explanation:
This line defines the numUnique method
public static int numUnique(int list[]) {
This initializes the number of unique elements to 1
int unique = 1;
This iterates through the list
for (int i = 1; i < list.length; i++) {
The following iteration checks for unique items
int j = 0;
for (j = 0; j < i; j++) {
if (list[i] == list[j]) If current element is unique, break the iteration
break;
}
if (i == j)
unique++;
}
This returns the number of unique items in the list
return unique;
