Chapter 21, Problem 21.17E
Program Plan Intro
Counting Number of Vowels
Program Plan:
- Include the required header files.
- Define the “main” function.
- Create a string object str and accept input in it.
- Create character array vowel with five vowels.
- Create integer array freq for frequency and count.
- Assign count to 0.
- Transform str to lower case.
- Use an outer loop to iterate through vowel array.
- Assign current freq to 0.
- Traverse through the str.
- Check if the current value of str is a vowel.
- If vowel then increment current freq and count.
- Display the total number of vowels in str.
- Display the frequency of each vowel using a loop.

(Financial: credit card number validation) Credit card numbers follow certain pat-
terns. A credit card number must have between 13 and 16 digits. It must start with:
4 for Visa cards
5 for Master cards
37 for American Express cards
6 for Discover cards
In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card
numbers. The algorithm is useful to determine whether a card number is entered
correctly or whether a credit card is scanned correctly by a scanner. Credit card
numbers are generated following this validity check, commonly known as the
Luhn check or the Mod 10 check, which can be described as follows (for illustra-
tion, consider the card number 4388576018402626):
1. Double every second digit from right to left. If doubling of a digit results in a
two-digit number, add up the two digits to get a single-digit number.
4388576018402626
→ 2 * 2 = 4
→ 2 * 2 = 4
→ 4 * 2 = 8
→ 1 * 2 = 2
6 * 2 = 12 (1+ 2 = 3)
→ 5 * 2 = 10 (1+ 0 = 1)
→ 8 * 2 = 16 (1 + 6 = 7)
→ 4 * 2 = 8
(Sort three integers) Write a program that prompts the user to enter THREE integers and
display the integers in decreasing order.
Prepare your problem analysis and algorithm (pseudocode or flowchart) to plan your
solution.
(Financials: currency exchange) Write a program that prompts the user to enter the exchange rate from currency in U.S. dollars to Rupees PKR. Prompt the user to enter 0 to convert from U.S. dollars to Rupees PKR and 1 to convert from Rupees PKR and U.S. dollars. Prompt the user to enter the amount in U.S. dollars or Rupees PKR to convert it to Rupees PKR or U.S. dollars, respectively. Use c++ program.

- (Bar-Chart Printing Program) One interesting application of computers is drawing graphsand bar charts. Write a program that reads five numbers (each between 1 and 30). For each numberread, your program should print a line containing that number of adjacent asterisks. For example,if your program reads the number seven, it should print *******.arrow_forward(Display a pattern) Write a program that displays the following pattern:JJ aaa v vaaaJ J aa v v a aJ aaaa v aaaaarrow_forward(Average a Sequence of Integers) Write a program that calculates and prints the average ofseveral integers. Assume the last value read with scanf is the sentinel 9999. A typical input sequencemight be10 8 11 7 9 9999indicating that the average of all the values preceding 9999 is to be calculatedarrow_forward
- (Sum a Sequence of Integers) Write a program that sums a sequence of integers. Assume thatthe first integer read with scanf specifies the number of values remaining to be entered. Your program should read only one value each time scanf is executed. A typical input sequence might be5 100 200 300 400 500where the 5 indicates that the subsequent five values are to be summed.arrow_forward(Count the letters in a string) Write a function that counts the number of letters in a string using the following header: def countLetters(s) : Write a test program that prompts the user to enter a string and displays the number of letters in the string. the answer should be in python.arrow_forward5. (Algebra: solve 2 X 2 linear equations) You can use Cramer's rule to solve the following 2 X 2 system of linear equation: ax + by = e cx + dy = f ● x = ed - bf bc ad y = af - ec ad bc - Write a program that prompts the user to enter a, b, c, d, e, and f and display the result. If ad- bc is 0, report that The equation has no solution. Enter a, b, c, d, e, f: 9.0, 4.0, 3.0, -5.0, -6.0, -21.0 Enter x is -2.0 and y is 3.0 Enter a, b, c, d, e, f: 1.0, 2.0, 2.0, 4.0, 4.0, 5.0 Enter The equation has no solutionarrow_forward
- (Integers Added Together) Create a program that employs the for statement to sum a succession of integers in a single line. Assume that the first integer read defines the number of values that must be entered before the next one may be read. Your software should only read one value per input statement in order to avoid memory leaks. A typical input sequence may be 5 100 200 300 400 500 (or something like). where the number 5 signifies that the items after it are to be added together.arrow_forward(Intro to Python) Q1. Given a string S with even length: Write an expression to print out the first half of the string Write an expression to print the second half of the stringarrow_forward(Count positive and negative numbers and compute the average of numbers) Write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the maximum, minimum, and average as a floating-point number. Here is a sample run:Enter an integer, the input ends if it is 0: 1 2 -1 3 0The number of positives is 3The number of negatives is 1The maximum is 3.0The minimum is -1.0The average is 1.25arrow_forward

(1 pt) Examples of strings that can be accepted: Jill, Allen Jill , Allen Jill,Allen Ex: Enter input string:Jill, Allen (2) Print an error message if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. (2 pts)Ex: Enter input string:Jill AllenError: No comma in string. Enter input string:Jill, Allen (3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings.
