PROGRAMMING ASSIGNMENT– IV
Q#1: Write a program that reads a number N calculates and displays the reverse of N. e.g, 3465789
becomes 9875643.
Hint: use the division and modulus operators to separate the number into its individual digits.
Q # 2 A palindrome is a number or a text phrase that reads the same backwards as forwards. For
example, each of the following integers is a palindrome: 121, 55555, 4554 and 113311. Write a
program that reads in a five-digit integer and determines whether it is a palindrome.
Q # 3 Write a program that reads numbers repeatedly until 0 (zero) is entered, find and display the
smallest and largest number. Use while loop statement.
Q # 4 Write a program that read unsigned numbers in the range 10 – 60000 continually until 0 (zero)
value is entered. Find and display how many numbers are completely divisible by 9, odd and even.
Use while loop statement.
Q # 5 Write a program that uses a while loop statement to calculate and print the average of several
integers. Assume the last value read is the sentinel 9999. A typical input sequence might be
10 8 11 7 9 9999
Indicating that the program should calculate the average of all the values preceding 9999.
Q # 6 Drivers are concerned with the mileage obtained by their automobiles. One driver has kept
track of several tankfuls of gasoline by recording miles driven and gallons used for each tankful.
Develop a program that uses a while statement to input the miles driven and gallons used for each
tankful. The program should calculate and display the miles per gallon obtained for each tankful and
print the combined miles per gallon obtained for all tankfuls up to this point.
Q # 7 One large chemical company pays its salespeople on a commission basis. The salespeople each
receive $200 per week plus 9 percent of their gross sales for that week. For example, sales person
who sells $5000 worth of chemicals in a week receives $200 plus 9 percent of $5000, or a total of
$650. Develop a program that uses a while 2/5 statement to input each salesperson’s gross sales for
last week and calculates and displays that salesperson’s earnings. Process one salesperson’s figures at
a time.
Q # 8 Develop a program that uses a while statement to determine the gross pay for each of several
employees. The company pays “straight time” for the first 40 hours worked by each employee and
pays “time and a half” for all hours worked in excess of 40 hours. You are given a list of the
employees of the company, the number of hours each employee worked last week and the hourly rate
of each employee. Your program should input this information for each employee and should
determine and display the employee’s gross pay.
