Programming & Computer Science Answers

1. In the code editor, you are provided with a main() function that asks the user for 2 integers. Then, a function call to a function named, exchangeGift() is made and the addresses of the 2 integers are passed.
2. This exchangeGift() function hasn't been implemented yet so this is your task. This has the following description:
3. Return type - void
4. Name - exchangeGift
5. Parameters - 2 addresses of 2 integers
6. Description - swaps the value of the 2 integers and then adds 100 to the 2nd integer (or 2nd parameter)
7. DO NOT EDIT THE MAIN

Input

1. First integer

2. Second integer

Output

Enter·integer·1:·10
Enter·integer·2:·20
20·110

#include <iostream>

using namespace std;

int main(void) {

  int a, b;

  cout << "Enter integer 1: ";

  cin >> a;

  cout << "Enter integer 2: ";

  cin >> b;

  exchangeGift(&a, &b);

  cout << a << " " << b;

  return 0;

}

Instructions:

1. In the code editor, you are provided with an initial code where a constant variable is declared.
2. Your only task is to assign the address of this variable to the first pointer found at line 10.

Output

My·destiny·=·11

#include <iostream>

using namespace std;

int main(void) {

  int destiny = 22;

  int *ptr1, *ptr2, *ptr3;

  // TODOFill in the blank

  ptr1 = ;

  ptr2 = ptr1;

  ptr3 = ptr2;

  cout << "My destiny = " << *ptr3;

  return 0;

}

Create an assembly program that would check if the input character is a numeric character. alphabet (letter) or a special character.

HINT: Each character has a corresponding decimal and hex values in the ASC table. Use ASCII table.

-write a program using for loop - show numbers from(1,150)increased by 3 only print odd numbers

Create a Java program that asks the user to input a student number. The format of the student number is a sequence of the following:

Four (4) digits

A dash

Two (2) digits

A dash

Three (3) digits

Display a welcome message if the student number is valid; otherwise, show an appropriate error message. Do not copy the welcome message in the sample output.

Implement the following problem statement in python along with test cases. Let’s say you have a Customer class and you want to test calculate bill method of customer class. Bill calculation will depend on list of items customer purchased

create two class names User and administrator. the administrator class should inherit from the user class and the two classes should be members of the namespace named User Namespace.

Create an assembly program that would check if the input character is a numeric character. alphabet (letter) or a special character.

HINT: Each character has a corresponding decimal and hex values in the ASC table. Use ASCII table.

Implement the function find_roots to find the roots of the quadratic equation:= ax2 + bx + c = 0. the function should return a tuple containing roots in any order. If the equation has only one solution. The Equation will always have at least one solution. 

The roots of the quadratic equation can be found with the following formula :

-b = +- square_root b² - 4ac

for example, find _roots (2, 10, 8) should return (-1, -4) or (-4, -1) as the roots of the equation 2x² + 10X + 8 are -1 and -4

I don't have the question but I can explain.

if given n=4,

we should able to give 4 rows and 4 column matrix as input. matrix consists of 0's and 1's

ex;- 0 1 0 0

0 0 1 0

0 1 0 1

1 1 0 0

 the 0 represents an empty space. the 1 represents a mine. you have to replace each mine with a x and each empty space with a number of adjacent mines

above example should print

1 X 2 1

2 3 X 2

3 X 4 X

X X 3 1

so sample input

4

0 1 0 0

0 0 1 0

0 1 0 1

1 1 0 0

and output should be

1 X 2 1

2 3 X 2

3 X 4 X

X X 3 1
