Concept explainers
A)
Explanation of Solution
Analysis of given code:
The given code is used to print “Hello world” once. The process is carried out using a “do…while” loop. Initially the “count” variable is assigned with a value “3”. The loop executes till the value of “count” is lesser than “1”.
Given code segment:
//Include necessary header file
#include <iostream>
using namespace std;
//Function main
int main()
{
// Declare and initialize a variable
int count = 3; //Line 1
//Loop
do //Line 2
{ //Line 3
// Print statement
cout<<"Hello World...
B)
Explanation of Solution
Analysis of given code:
The given code is used to print value of the variable “val”. The process is carried out using a “do…while” loop. Initially the “val” variable is assigned with a value “5”. The loop executes till the value of “val” is greater than or equal to “5”.
Given code segment:
// Include necessary header file
#include <iostream>
using namespace std;
// Driver function main()
int main()
{
// Declare and initialize variable
int val = 5; //Line 1
//Loop
do //Line 2
&...
C)
Explanation of Solution
Analysis of given code:
The given code is used to print the value of variables “number” and “count” on the screen. The “do…while” loop is used to increment the value of variable “number” by “2” add the value of variable “count” by “1”.
Given code segment:
// Include necessary header file
#include <iostream>
using namespace std;
// Function main
int main()
{
// Declare and initialize variables
int count = 0, number = 0, limit = 4; //Line 1
//Loop
do //Line 2
{ //Line 3
// Increment number by 2
number+=2; //Line 4
// Increament count by 1
count++; //Line 5
} //Line 6
//Condition
while(count < limit); //Line 7
//Display number and count
cout << number << " " << count <<endl; //Line 8
//Return value
return 0;
}
Explanation:
- In “Line 1”, declare the variables “count”, “number”, and “limit” and initialize it to “0”, “0”, and “4” respectively...

- Consider records of employees each consists of employee's first name (string), number of hours worked (int)and hourly rate in Bahraini Dinar BD. (double).Write a program that reads from the user multiple records for multiple employees and displays the following onscreen:(a) the salary for each employee (Salary = Hours Worked x Hourly rate.)(b) the number of employees(c) the highest salary with employee name.Reading records of employees should stop when the user enter `stop' for the employee name. Sample I/O of theprogram is shown in the example below.arrow_forwardQ3: Write a program in which user is asked to enter two integers (divisor and dividend) and computes the quotient and remainder. To compute quotient and remainder, both divisor and dividend should be integers.arrow_forwardprogram4_2.pyWrite a program that displays a table of inches from 1-12 and equivalent lengths in centimeters. You can find the conversion factor online if necessary. Store this factor in a properly named constant in your program.

- my_round(number, integer): Based on the built-in round(...) function. Takes an integer or float and returns a rounded float value that is the number rounded to the second argument's decimal place. First argument can be any float or integer. Second argument must be an integer. Examples: my_round(1234.5678, 2) and round(1234.5678, 2) should return 1234.57. my_round(1234.5678, -2) and round(1234.5678, -2) should return 1200.0.arrow_forward4.15 LAB: Hailstone sequence Given a positive integer n, the following rules will always create a sequence that ends with 1, called the hailstone sequence: If n is even, divide it by 2 If n is odd, multiply it by 3 and add 1 (i.e. 3n +1) Continue until n is 1 Write a program that reads an integer as input and prints the hailstone sequence starting with the integer entered. Format the output so that ten integers, each separated by a tab character (\t), are printed per line. The output format can be achieved as follows:print(n, end='\t') Ex: If the input is: 25 the output is: 25 76 38 19 58 29 88 44 22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1arrow_forwardThis exercise is designed to assess student’s skills of writing programs using arrays and loops.Exercise 1:Write a C++ program for a number guessing game. The program generates and stores a random number and prompts a user to guess the number. If user guess is less than the number, display “Sorry, guess is too low”, if user guess is greater than the number, display “Sorry, guess is too high”. If user guesses the right number, display “Congratulations, you have guessed the number”, and number of users tries to guess a number. The program should keep on taking a user input, until user guesses the number. Sample Output 1 (Number 50):Enter a number to guess: 50“Congratulations, you have guessed the number” in first try. Sample Output 2 (Number 50):Enter a number to guess: 25“Sorry, guess is too low”Enter a number to guess: 60“Sorry, guess is too high”Enter a number to guess: 50 “Congratulations, you have guessed the number in 3 tries”,arrow_forward
- Determine the distance between point (x1, y1) and point (x2, y2), and assign the result to pointsDistance.
