QUESTION 1:
Imagine that the IRA is giving a stimulus package in the COVID-19 season. The package amount is determined by the number of adults in the family and the total amount of salary the family gets.

Each adult will get 1200 dollars if the total salary is 100000 or less.

Each adult will get 800 dollars if the total salary is 150000 or less.

Write a python program to ask the user the number of adults in the family and the total number of family salary and determine the total amount of stimulus package the IRA will provide for that family.

QUESTION 2:

Write a program that will ask the user length and width of a right triangle and find the area of the right-angled triangle. The formula for finding the area of a right-angle triangle is

ab/2. Also, find out the result if you calculate as (ab)/2. Is it the same? If it is same, why it is the same. If it is not the same, why it is not the same.

Please note that this problem have to use sstream library in c++

(1) Prompt the user for a title for data. Output the title. (1 pt)

Ex:

Enter a title for the data:

You are given two numbers n and m representing the dimensions of an n × m rectangular board. The rows of the board are numbered from 1 to n, and the columns are numbered from 1 to m. Each cell has a value equal to the product of its row index and column index (both 1-based); in other words, board[i][j] = (i + 1) * (j + 1).

Initially, all the cells in the board are considered active, though some of them will eventually be deactivated through a sequence of queries - specifically, you will be given an array queries, where each query is of one of the following 3 types:

• [0] - find the minimum value among all remaining active cells on the board.
• [1, i] - deactivate all cells in row i;
• [2, j] - deactivate all cells in column j;

Given the dimensions n, m, and the array of queries, your task is to return an array consisting of calculated values (results of the queries of the 0^th type), in the order in which they were calculated.

1) Translate the following C program to Pep/9 assembly language. Please attach screenshot of Pep/9 simulator running the program.

#include <stdio.h.>

int main() {

int numitms,j,data,sum;

scanf("%d", &numitms);

sum=0;

for (j=1;j<=numitms;j++) {

scanf("%d", &data);

sum+=data;

}

printf("sum: %d\n",sum);

return0;

}

1, Create a class Car. The class has four instance fields:

• make (String - admissible values: Chevy, Ford, Toyota, Nissan, Hyundai)
• size (String - admissible values: compact, intermediate, fullSized),
• weight (int - admissible values: 500 <= weight <= 4000)
• horsePower (int - admissible values: 30 <= horsePower <= 400)

Provide

• a default constructor that sets String values to null and int values to 0
• a parameterized constructor that sets all four instance fields to the parameter values
• setters and getters for all instance fields
• a decent toString method
  

2. Create a class CarFactory

It provides just one method public static Car createRandomCar() which creates a random car instance with value chosen from the admissible set/range.

  while(cin >> solution){

    cin >> input;

    Stack<char> stack;

    string result;

     //The input file is in the format "expected_solution infix_expression",

     //where expected_solution is the infix_expression in postfix format

    for(int i=0; i<input.length(); ++i){

      // WRITE CODE HERE to store in 'result' the postfix transformation of 'input'

    }

    // You need to do some extra stuff here to store in 'result' the postfix transformation of 'input'

    // Checking whether the result you got is correct

    if(solution == result){

      cout << "line " << line_counter << ": OK [" << solution << " " << result << "]" << endl;

    }else{

      cout << "line " << line_counter << ": ERROR [" << solution << " " << result << "]" << endl;

    }

    line_counter++;

  }

}

Implement a stack and solutions to the following problems: balancing parenthesis, evaluating postfix expressions and transforming infix expressions into postfix expressions.

infix2postfix.cpp

- create main method to transform an infix expression into postfix

1. Write a C++ program, for.cpp, that reads three integers. The first two specify a range, call them bottom and top, and the other gives a step value. The program should print four sequences using for loops:

• Each value in the range from bottom to top

• Each value in the range from top to bottom, reverse counting

• Every second value in the range from bottom to top

• Every value from bottom to top increasing by step

  a: If bottom is less than top when entered, the program will exchange the two values.
  b: If step is negative, the program will be set to its absolute value (positive equivalent).

  Sample Run 1 (should have same text and spacing as in examples):

  Enter the bottom value in the range: 3
  Enter the top value in the range: 20
  Enter the step value: 6
  

  Values from 3 to 20:
  3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

  Values from 20 to 3:
  20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3

  Every second value from 3 to 20:
  3 5 7 9 11 13 15 17 19
  

  Every 6th value from 3 to 20:
  3 9 15
  

Sample Run 2 (demonstrating part a and b):

Enter the bottom value in the range: 72 Enter the top value in the range: 56 Enter the step value: -4

Values from 56 to 72:
56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72

Values from 72 to 56:
72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56

Every second value from 56 to 72:
56 58 60 62 64 66 68 70 72

Every 4th value from 56 to 72:
56 60 64 68 72

Write a C++ program, falling.cpp, that inputs a distance in meters from the user and computes the amount of time for the object falling from that distance to hit the ground and the velocity of the object just before impact. Air resistance is discounted (assumed to fall in a vacuum).

To compute the time, use the formula: t = Square Root (2d / g)

where d is the distance in meters and g is the acceleration due to gravity on earth (use 9.807 meters/sec2). The time is measured in seconds.

To compute the velocity, use the formula:
v = Square Root (2dg)
The velocity is measured in meters per second.

You are required to write the following functions:

// Computes the amount of time for an object to fall to the // ground given the distance to fall as a parameter. The // time is returned (computeTime does not print anything). double computeTime (double distance);

// Computes the final velocity of an object falling to the // ground given the distance to fall as a parameter. The // velocity is returned (computeVelocity does not print // anything).

double computeVelocity (double distance);

// print prints its three parameters with labels.
// Print does not return a value.
void print (double distance, double time, double velocity);

Sample run:

Enter the distance: 100

Distance: 100.00 meters Time: 4.52 seconds
Velocity: 44.29 meters/second

Double values should be printed with two digits after the decimal.

Q2. The 9’s complement of a decimal digit d (0 to 9) is defined to be 9 - d. A logic circuit produces the 9’s complement of an input digit where the input and output digits are represented in BCD. Label the inputs A, B, C, and D, and label the outputs W, X, Y and Z. (a) Determine the minterms and don’t-care minterms for each of the outputs. (b) Determine the maxterms and don’t-care maxterms for each of the outputs. ***Please kindly note, questions are solved as chapter 4

Write a loan amortization program in C++. Assume the loan is paid off in equal monthly installments. To compute the monthly payment you must know: 1.the initial loan value 2. # of months the loan is in effect 3. APR. You should prompt the user for each of these 3 things then compute the monthly payment. The following formula is useful: Payment = (factor * value * monthly_rate) / (factor - 1) where factor = (1 + monthly_rate) ^ number_of_months. Then set up the amortization table that will show for each month the starting balance, the interest paid, the payment amount and the new balance. Use comments in the program and use a function that compute_payment given 3 values of loan amount, APR, and loan length. Most variables in the program should be doubles. The output should have headers for each column, echo the input values, and must be aligned.

1. Create a program named MergeSort.java then copy the following code to your program:
   • public static void mergeSort(int[] arr){
        mergeSortRec(arr, 0, arr.length-1);
     }
     private static void mergeSortRec(int[] arr, int first, int last){
        if(first<last){
         int mid=(first+last)/2;
     mergeSortRec(arr, first, mid);
         mergeSortRec(arr, mid+1,last);
         merge(arr, first, mid, mid+1, last);
        }
     }
     private static void merge(int[] arr, int leftFirst,
        int leftLast, int rightFirst, int rightLast){
        int[] aux=new int[arr.length];
        //extra space, this is downside of this algorithm
        int index=leftFirst;
        int saveFirst=leftFirst;
        while(leftFirst<=leftLast && rightFirst <=rightLast){
     if(arr[leftFirst]<=arr[rightFirst]){
        aux[index++]=arr[leftFirst++];
         }else{
        aux[index++]=arr[rightFirst++];
         }
        }
        while(leftFirst<=leftLast){
         aux[index++]=arr[leftFirst++];
        }
        while(rightFirst<=rightLast)
         aux[index++]=arr[rightFirst++];
        for(index=saveFirst; index<=rightLast; index++)
         arr[index]=aux[index];
     }
2. Write a main method that accepts three numbers N, A, B (assume A<B) from the command argument list, then use the number N to create an N-element int array.
3. Assign random numbers between [A, B] to each of the N elements of the array.
4. Call mergeSort method to sort the array.
5. Write instructions to record the time spent on sorting.
6. (Optional) you may write code to verify the array was sorted successfully.
7. Once completed, test your program with different numbers N, A, B and screenshot your result. Your result should include the number of elements and sorting time.
8. Please include the following in the Word document you created for the assignment for the final submission:  
   • Copy/paste your completed code in MergeSort.java
   • Insert at least one screenshot of the running output in #7 above
   • Answer this question: What is the average Big O for this sort?

Provide a formatted printing statement that yields $▯▯323.500 for input 323.5. Note that ▯ means a space.

Write a code to initialize a 2D array with random integers (not has to be different). Write a function to count the number of cells that contain an even number within the 2D array.

C++

The monthly payment for a given loan pays the principal and the interest. The monthly interest is computed by multiplying the monthly interest rate and the balance (the remaining principal). The principal paid for the month is therefore the monthly payment minus the monthly interest. Write a pseudocode and a Python program that let the user enter the loan amount, number of years, and interest rate, and then displays the amortization schedule for the loan (payment#, interest, principal, balance, monthly payment). Hint: use pow function (example, pow (2, 3) is 8. Same as 2 **3. ); monthly payment is the same for each month, and is computed before the loop.
