Write a program that mimics a calculator. The program should take as input two integers and the operation to be performed. It should then output the numbers, the operator, and the result. For division, if the denominator is zero, output an appropriate message. Limit the supported operations to -/ *and write an error message if the operator is not one of the supported operations. Here is some example output:3 4
Answers
Answer:
The cpp calculator program is as follows.
#include <iostream>
using namespace std;
int main()
{
//variables to hold two numbers and operation
int num1;
int num2;
char op;
char operations[] = {'-', '/', '*'};
std::cout << "Enter first number: ";
cin>>num1;
std::cout << "Enter second number: ";
cin>>num2;
do
{
std::cout << "Enter the operation to be performed(-, /, *): ";
cin>>op;
if(op!=operations[0] && op!=operations[1] && op!=operations[2])
std::cout << "Invalid operator." << std::endl;
}while(op!=operations[0] && op!=operations[1] && op!=operations[2]);
std::cout<< "Numbers are "<< num1 <<" and "<< num2 <<std::endl;
std::cout << "Operator is " <<op<< std::endl;
if(op==operations[0])
std::cout << "Result is "<< num1-num2 << std::endl;
if(op==operations[1])
if(num2==0)
std::cout << "Denominator is zero. Division cannot be performed." << std::endl;
else
std::cout << "Result is "<< num1/num2 << std::endl;
if(op==operations[2])
std::cout << "Result is "<< num1*num2 << std::endl;
return 0;
}
OUTPUT
Enter first number: 12 Enter second number: 0 Enter the operation to be performed(-, /, *): + Invalid operator. Enter the operation to be performed(-, /, *): / Numbers are 12 and 0 Operator is / Denominator is zero. Division cannot be performed.
Explanation:
1. Declare two integer variables to hold the numbers.
int num1;
int num2;
2. Declare one character variable to hold the operation to be performed.
char op;
3. Declare one character array to hold all the operations.
char operations[] = {'-', '/', '*'};
4. User input is taken for the two numbers followed by the operation to be performed.
5. Validation is applied for incorrect operation entered by the user. This is done using if statement inside a do-while loop.
6. Once the correct input is obtained, the calculator program performs the required operation on the numbers. This is done using if statements.
7. If the denominator number is zero for division operation, a message is displayed to the user.
8. The numbers followed by the operation chosen by the user are displayed.
9. The result of the operation is computed and displayed.

Answer:
1. Casual End Users
These are the users who occasionally access the database but they require different information each time. They use a sophisticated database query language basically to specify their request and are typically middle or level managers or other occasional browsers. These users learn very few facilities that they may use repeatedly from the multiple facilities provided by DBMS to access it.
2. Naive or parametric end users
These are the users who basically make up a sizeable portion of database end users. The main job function revolves basically around constantly querying and updating the database for this we basically use a standard type of query known as canned transaction that have been programmed and tested. These users need to learn very little about the facilities provided by the DBMS they basically have to understand the users’ interfaces of the standard transaction designed and implemented for their use. The following tasks are basically performed by Naive end users:
The person who is working in the bank will basically tell us the account balance and post-withdrawal and deposits.
Reservation clerks for airlines, railway, hotels, and car rental companies basically check availability for a given request and make the reservation.
Clerks who are working at receiving end for shipping companies enter the package identifies via barcodes and descriptive information through buttons to update a central database of received and in transit packages.
3. Sophisticated end users
These users basically include engineers, scientist, business analytics and others who thoroughly familiarize themselves with the facilities of the DBMS in order to implement their application to meet their complex requirement. These users try to learn most of the DBMS facilities in order to achieve their complex requirements.

Here's an example program in Python that stores the largest and smallest of three integer values entered by the user:
```python
# Declare variables for largest and smallest
largest = None
smallest = None
# Prompt user to enter three integers
num1 = int(input("Enter first integer: "))
num2 = int(input("Enter second integer: "))
num3 = int(input("Enter third integer: "))
# Determine largest number
if num1 >= num2 and num1 >= num3:
largest = num1
elif num2 >= num1 and num2 >= num3:
largest = num2
else:
largest = num3
# Determine smallest number
if num1 <= num2 and num1 <= num3:
smallest = num1
elif num2 <= num1 and num2 <= num3:
smallest = num2
else:
smallest = num3
# Output results
print("The largest value is", largest)
print("The smallest value is", smallest)
```
In this program, the variables `largest` and `smallest` are declared and initialized to `None`. Three additional variables `num1`, `num2`, and `num3` are declared and initialized with integer values entered by the user using the `input()` function and converted to integers using the `int()` function.
The program then uses a series of `if` and `elif` statements to determine the largest and smallest of the three numbers, based on their values. The `largest` and `smallest` variables are updated accordingly.
Finally, the program outputs the results using two `print()` statements.v

Perform an “average case” time complexity analysis for Insertion-Sort, using the given proposition
and definition. I have broken this task into parts, to make it easier.
Definition 1. Given an array A of length n, we define an inversion of A to be an ordered pair (i, j) such
that 1 ≤ i < j ≤ n but A[i] > A[j].
Example: The array [3, 1, 2, 5, 4] has three inversions, (1, 2), (1, 3), and (4, 5). Note that we refer to an
inversion by its indices, not by its values!
Proposition 2. Insertion-Sort runs in O(n + X) time, where X is the number of inversions.
(a) Explain why Proposition 2 is true by referring to the pseudocode given in the lecture/textbook.
(b) Show that E[X] = 1
4n(n − 1). Hint: for each pair (i, j) with 1 ≤ i < j ≤ n, define a random indicator
variable that is equal to 1 if (i, j) is an inversion, and 0 otherwise.
(c) Use Proposition 2 and (b) to determine how long Insertion-Sort takes in the average case.
Answers
a. Proposition 2 states that Insertion-Sort runs in O(n + X) time, where X is the number of inversions.
b. The expected number of inversions, E[X], E[X] = 1/4n(n-1).
c. In the average case, Insertion-Sort has a time complexity of approximately O(1/4n²).
How to calculate the information(a) Proposition 2 states that Insertion-Sort runs in O(n + X) time, where X is the number of inversions. To understand why this is true, let's refer to the pseudocode for Insertion-Sort:
InsertionSort(A):
for i from 1 to length[A] do
key = A[i]
j = i - 1
while j >= 0 and A[j] > key do
A[j + 1] = A[j]
j = j - 1
A[j + 1] = key
b. The expected number of inversions, E[X], can be calculated as follows:
E[X] = Σ(i,j) E[I(i, j)]
= Σ(i,j) Pr((i, j) is an inversion)
= Σ(i,j) 1/2
= (n(n-1)/2) * 1/2
= n(n-1)/4
Hence, E[X] = 1/4n(n-1).
(c) Using Proposition 2 and the result from part (b), we can determine the average case time complexity of Insertion-Sort. The average case time complexity is given by O(n + E[X]).
Substituting the value of E[X] from part (b):
Average case time complexity = O(n + 1/4n(n-1))
Simplifying further:
Average case time complexity = O(n + 1/4n^2 - 1/4n)
Since 1/4n² dominates the other term, we can approximate the average case time complexity as:
Average case time complexity ≈ O(1/4n²)
Therefore, in the average case, Insertion-Sort has a time complexity of approximately O(1/4n²).

RAM and cache memory are examples of online storage as they provide direct and fast access to data. CD-ROM, floppy disk, and registers are examples of offline storage as they require external devices or are part of the processor's internal storage.
Online Storage:
1. RAM (Random Access Memory): RAM is a type of volatile memory that provides temporary storage for data and instructions while a computer is running. It is considered online storage because it is directly accessible by the computer's processor and allows for fast retrieval and modification of data.
2. Cache Memory: Cache memory is a small, high-speed memory located within the computer's processor or between the processor and the main memory. It is used to temporarily store frequently accessed data and instructions to speed up processing. Cache memory is considered online storage because it is directly connected to the processor and provides quick access to data.
Offline Storage:
1. CD-ROM (Compact Disc-Read-Only Memory): A CD-ROM is a type of optical disc that stores data and can only be read. It is considered offline storage because data is stored on the disc and requires a CD-ROM drive to read the information.
2. Floppy Disk: A floppy disk is a portable storage medium that uses magnetic storage to store data. It is considered offline storage because it requires a floppy disk drive to read and write data.
3. Registers: Registers are small, high-speed storage locations within the computer's processor. They hold data that is currently being used by the processor for arithmetic and logical operations. Registers are considered offline storage because they are part of the processor's internal storage and not directly accessible or removable.
