The question is incomplete as there is no link pointing to the houseType struct of chapter 1.
So, I've answered the question from scratch
See attachment for explanation where I used comments to explain each line.
The program is as follows:
#include <iostream>
using namespace std;
struct houseType{

};
int main() {
houseType hT;
cout << "Enter the price of both house: ";

Construct a class that will model a quadratic expression (ax^2 + bx + c). In addition to a constructor creating a quadratic expression, the following operations can be performed:
- query quadratic expression for each coefficient
- evaluate the quadratic expression at a specified value
- determine the number of real zeros (solutions to associated quadratic equation)
- determine the real zeros
Also construct a test program which will test whether your implementation of this class is correct.
Answer:
Following are the code to this question:
#include <iostream>//header file
#include<math.h>//header file
using namespace std;
class Quadratic//defining a class Quadratic
{
private:
double a,b,c;//defining a double variable
public:
Quadratic()//defining default constructor
{
a = 0;//assigning value 0
b = 0;//assigning value 0
c = 0;//assigning value 0
}
Quadratic(double a, double b, double c)//defining a parameterized constructor
{
this->a = a;//use this keyword to hold value in a variable
this->b = b;//use this keyword to hold value in b variable
this->c = c;//use this keyword to hold value in c variable
}
double getA() //defining a get method
{
return a;//return value a
}
void setA(double a)//defining a set method to hold value in parameter
{
this->a = a;//assigning value in a variable
}
double getB() //defining a get method
{
return b;//return value b
}
void setB(double b)//defining a set method to hold value in parameter
{

}
double getC() //defining a get method
{
return c;//return value c
}
void setC(double c)//defining a set method to hold value in parameter
{
this->c = c;//assigning value in c variable
}
double Evaluate(double x)//defining a method Evaluate to hold value in parameter
{
return ((a*x*x)+(b*x)+c);//return evaluated value
}
double numberOfReal()//defining a method numberOfReal to calculates the real roots
{
return (b*b)-(4*a*c);//return real roots
}
void findroots()//defining a method findroots
{
double d=numberOfReal();//defining double variable to hold numberOfReal method value
if(d<0)//use if block to check value of d less than 0
cout<<"Equation has no real roots"<<endl;//print message
else
{
double r1=(-b+sqrt(numberOfReal()))/(2*a);//holding root value r1
double r2=(-b-sqrt(numberOfReal()))/(2*a);//holding root value r2
if(r1==r2)//defining if block to check r1 equal to r2
cout<<"Equation has one real root that is "<<r1<<endl;//print message with value
else//else block
cout<<"The equation has two real roots that are "<<r1<<" and "<<r2<<endl;////print message with value
}
}
void print()//defining a method print
{
cout<< a << "x^2 + " << b << "x + " << c <<endl;//print Quadratic equation
}
};
int main()//defining main method
{
Quadratic q(5,6,1);//creating Quadratic class object that calls parameterized constructor
q.print();//calling print method
cout<<q.numberOfReal()<<endl;//calling method numberOfReal that prints its value
q.findroots();//calling method findroots
cout<<q.Evaluate(-1);//calling method Evaluate that prints its value
return 0;
}
Output:
5x^2 + 6x + 1
16
The equation has two real roots that are -0.2 and -1
0
Explanation:
In the above code, a class "Quadratic" is declared, which is used to define a default and parameter constructor to holds its parameter value.
In the next step, the get and set method is defined that holds and returns the quadratic value, and "Evaluate, numberOfReal, findroots, and print" in the evaluate method a double variable is used as a parameter that returns evaluated value.
In the "numberOfReal" method it calculates the real roots and returns its value. In the "findroots" method a double variable "d" is declared that hold "numberOfReal" value,
and use a conditional statement to check its value, and in the print method, it prints the quadratic equation.
In the main method, the lass object it calls the parameterized constructor and other methods.
Write a program that reads a list of integers, and outputs the two smallest integers in the list, in ascending order. The input begins with an integer indicating the number of integers that follow. You can assume that the list will have at least 2 integers and fewer than 20 integers. Ex: If the input is: 5 10 5 3 21 2
Answer:
Follows are the code to the given question:
#include <iostream>//header file
using namespace std;
int main() //main method
{
int nums[20];//defining an array
int n,i,k;//defining integer variables
cout<<"Enter total number you want to insert: ";//print message
cin>>n;//input value of n
cout << "Enter array numbers: " << endl;//print message
for (i = 0;i<n;i++) //defining for loop for input values from user-end
{
cin >> nums[i];//input values
}
for (i = 0; i < n;i++) //defining for loop for count array values
{
for (k =i+1;k<n;k++)//defining for loop for arrange value in ascending order
{
if (nums[i] > nums[k])//checking first and second value
{
int t = nums[i];//defining integer variable that hold first element value in t
nums[i] = nums[k];//holding second element value in first element
nums[k] = t;//assign value in t
}
}
}
cout<<"Two smallest number in list are:";//print message
for (i = 0; i <2; ++i)//defining for loop that prints first two smallest value
cout<<nums[i]<<" ";//print value
return 0;
}
Output:
Enter total number you want to insert: 6
Enter array numbers:
5
10
5
3
21
2
Two smallest number in list are:2 3
Explanation:
In this code, an integer array "nums" is defined, and in the next step multiple integer variable is defined, that uses the for loop input value from the user-end, and in the next step, another two for loop is declared, that uses if block to arrange value into the ascending order at which it stores two smallest value in first and second position in the array element, and in the next step, it uses another for loop to print its element value.

Please read this lab exercise thoroughly, before attempting to write the program.
Write a program that reads the pairs of group number and student count from the text file (user must enter name of file) and:
Displays the number of groups in the file (5 %)
Displays the number of even and odd student count (5%)
Displays the sum of the even student count and the sum of the odd student count as well as the sum of all the student count (5%)
Displays the group numbers of the largest student count and the smallest student count (5 %)
Computes the average of the largest and smallest student count (10 %)
Compute the sum of ALL the digits in the largest student count (i.e. 952 – Sum is 9+5+2 = 16) (15 %)
Assume the contents of the file are as follows but that the pairs of data can change later:
1 25
2 123
3 475
4 61
5 77
6 910
7 234
8 138

18 7
19 876
20 347
21 450
The following is a sample output: User input in red
What is name of the input file? integers.dat
The number of groups in the file is 21
There are 12 odd student count and 9 even student count
The sum of the odd student count is 2645
The sum of the even student count is 4390
The sum of all the student count is 7035
The group number of the largest student count is 15
The group number of the smallest student count is 18
The average of 952 and 7 is 479.5
The sum of all the digits in the largest student count is 16
NOTE:
Use two decimal point precision for the average
To check your code, adjust one of the student count in the file, recompile your code and run again (suggest changing the largest or smallest student count )
Even though there are 21 pairs of numbers in the file, the program should NOT presume there will always be 21 pairs of numbers. In other words, you should not solve this problem by declaring 21 pairs of values. If I choose to use another integers.dat file other than the one provided with the assignment, your program should still work correctly with that file as well. All you can assume is that a series of integers will be read in from the file. Therefore, you need to implement a solution that uses the repetition control structures (for, while, do…while) in the reading and processing of these values to produce your output.
