//Directory Name:C:\tc\convert.cpp
// Programmer : Ali
//Brief Description: This Program [Source Code] is used to convert Celsius to
Fahrenheit
#include <iostream.h>
#include <conio.h>
int main()
{
clrscr(); // clear the console
windows
float celsius, fahrenheit;
// declare variable of type float
cout << "Enter Celsius temperature: ";
// simple display message on screen
cin >> celsius; // get input from keyboard
fahrenheit = 1.8 * celsius + 32; // perform
calculation
cout << "Fahrenheit = " << fahrenheit << endl;
// print output to console window
getche(); //pause the output windows
return 0;

| Important Points: |
Compilation of the every program always start from top to bottom
Execution of every program starts in the main() function
The main() function is declared to return an int, therefore it must return some
integer value. Zero is commonly used to indicate that the program terminated
successfully. |

a) Account number (an integer)
b) Balance at the beginning of the month
c) Total of all items charged by this customer this month

salespeople receive $200 per week plus 9 percent of their gross sales for that
week. For example, a salesperson who sells $5000 worth of chemicals in a week
receives $200 plus 9 percent of $5000, or a total of $650. Develop a C++
program that will input each salesperson's gross sales for last week and

| A palindrome is a number or a text phrase that reads
the same backwards as forwards. For example, each of the following five-digit
integers is a palindrome: 12321, 55555, 45554 and 11611. Write a
program (Deitel How to program in c++ solved exercise) in C/C++ that reads
in a five-digit integer and determines whether it is a palindrome.

| (Deitel How to program in c++ solved exercise)Input
an integer containing only 0s and 1s (i.e., a “binary” integer) and print its
decimal equivalent. (Hint: Use the modulus and division operators to pick off
the “binary” number’s digits one at a time from right to left. Just as in the
decimal number system where the rightmost digit has a positional value of 1 and
the next digit left has a positional value of 10, then 100, then 1000, etc., in
the binary number system, the rightmost digit has a positional value of 1, the
next digit left has a positional value of 2, then 4, then 8, etc. Thus the
decimal number 234 can be interpreted as 4 * 1 + 3 * 10 + 2 * 100. The decimal
equivalent of binary 1101 is 1 * 1 + 0 * 2 + 1 * 4 + 1 * 8 or 1 + 0 + 4 + 8, or
13.) |

| A company wants to transmit data over the telephone,
but they are concerned that their phones may be tapped. All of their data are
transmitted as four-digit integers. They have asked you to write a program that
encrypts their data so that it can be transmitted more securely. Your program
should read a four-digit integer and encrypt it as follows: Replace each digit
by (the sum of that digit plus 7) modulus 10. Then, swap the first digit with
the third, swap the second digit with the fourth and print the encrypted
integer. Write a separate program (Deitel How to program in c++ solved

it to form the original number. |

Write a program that prints the following patterns
separately one below the other. Use for loops to generate the patterns. All
asterisks (*) should be printed by a single statement of the form cout <<
'*'; (this causes the asterisks to print side by side). Hint: The last two
patterns require that each line begin with an appropriate number of blanks.
Extra credit: Combine your code from the four separate problems into a single
program that prints all four patterns side by side by making clever use of
nested for loops.

| One interesting application of computers is drawing
graphs and bar charts (sometimes called “histograms”). Write a program in C++
that reads five numbers (each between 1 and 30). For each number read, your
program should print a line containing that number of adjacent asterisks. For
example, if your program reads the number seven, it should print *******. |
A mail order house sells five different products
whose retail prices are product 1 — $2.98, product 2—$4.50, product 3— $9.98,
product 4—$4.49 and product 5—$6.87. Write a program that reads a series of
pairs of numbers as follows:
a) Product number
b) Quantity sold for one day Your program should use a switch statement to help
determine the retail price for each product. Your program should calculate and
display the total retail value of all products sold last week. |

| Pythagorean Triples) A right triangle can have sides
that are all integers. The set of three integer values for the sides of a right
triangle is called a Pythagorean triple. These three sides must satisfy the
relationship that the sum of the squares of two of the sides is equal to the
square of the hypotenuse. Find all Pythagorean triples for side1, side2 and
hypotenuse all no larger than 500. Use a triple-nested for-loop that tries all
possibilities. This is an example of “brute force” computing. You will learn in
more advanced computer science courses that there are many interesting problems
for which there is no known algorithmic approach other than using sheer brute
force. |
| A company pays its employees as
managers (who receive a fixed weekly salary), hourly workers (who receive a
fixed hourly wage for up to the first 40 hours they work and “time-and-a-half,”
i.e., 1.5 times their hourly wage, for overtime hours worked), commission
workers (who receive $250 plus 5.7% of their gross weekly sales), or
pieceworkers (who receive a fixed amount of money per item for each of the
items they produce—each pieceworker in this company works on only one type of
item). Write a program to compute the weekly pay for each employee. You do not
know the number of employees in advance. Each type of employee has its own pay
code: Managers have paycode 1, hourly workers have code 2, commission workers
have code 3 and pieceworkers have code 4. Use a switch to compute each
employee’s pay based on that employee’s paycode. Within the switch, prompt the
user (i.e., the payroll clerk) to enter the appropriate facts your program
needs to calculate each employee’s pay based on that employee’s paycode. |
