Max Function

Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.

Power Function

A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be...

C++ Programming Instructions

Write a program that prompts the user for a sequence of characters (all typed on a single line) and counts the number of vowels ('a', 'e', 'i', 'o', 'u'), consonants, and any other characters that appear in the input. The user terminates input by typing either the period (.) or exclamation mark character (!) followed by the Enter key on your keyboard.

Your program will not count white space characters.I.e., you will ignore white space characters.Though, the cin statement will skip white space characters in the input for you.
Your program will not be case-sensitive. Thus, the characters 'a' and 'A' are both vowels and the characters 'b' and 'B' are both consonants.

For example, the input How? 1, 2, 3. contains one vowel, two consonants, and six other kinds of characters.

IMPORTANT: Your program must use the while statement only when looping. I.e., do not use a for statement or any other looping statement.

Transcribed Image Text:Your solution will be graded based upon program behavior (passing tests). Your solution will not receive full credit (or receives no credit) if you fail to follow these restrictions: Your program must compile and run. Otherwise it will receive a zero. • Add your solution to the provided code template. • DO NOT use the iomanip preprocessor directive (see *hints below). • Your program must use the while statement only when looping. I.e., do not use a for statement or any other looping statement. • Use descriptive variable names. Avoid too short variable names, especially single letter variable names. • DO NOT start a variable name with a capital letter. • DO NOT use explicit type casting. Instead use coercion (see lecture notes). • DO NOT unnecessarily use parenthesis in an expression, e.g. an equation or formula. Parenthesis should only be used for grouping portions of an expression to change operator precedence order. For example, parenthesis are unnecessary in the expression (a + b + c). Instead use a + b + c. Parenthesis are necessary in the expression (a + b + c) / 3. • DO NOT use the break and continue statements in your solution. • Your program must be readable including indenting, spaces, and avoid lines that are too long. Use the the sample programs in the lecture notes as a guide. • Comment your program. Read the document at the "Lecture" link on Carmen under Modules- >Commenting Your Program-> Commenting your program. DO NOT comment every line. • Only use C++ statements presented in the course. I.e. statements and notation presented in the lecture notes and assigned readings. To receive full credit, only use C++ statements presented in the PowerPoint slides and assigned readings up to the slides on the while statement. Your solution will be graded based on passing test cases, formatting, and good choice of variable names. Write your solution in the provided code template. Please use the following HINTS to help you formulate your solution: You are NOT reading your input into a string. You will read each character one at a time into the variable character. DO NOT use the getline statement. You will use the cin statement (see the provided code template). Use a while statement to continue reading characters from the input one at a time until the user enters either the " or !' character. If the user enters white space then the cin statement will skip these for you. • Use accumulation variables that compute counts. • For each character from the input, use mutual exclusion to decide which accumulation variable to update. • You can use ASCII codes to help you determine whether or not a character is a consonant. The ASCII codes for the characters 'a' - 'z' are in the range 97-122 and the characters 'A' - 'Z' are in the range 65-90. • Determine the percentage of vowels in the input by computing the # of vowels divided by the total number of characters in the input. Display this percentage using:

Display this percentage using: cout.setf(ios:fixed); cout.precision(2); DO NOT include the iomanip preprocessor directive! Important!: Write your code incrementally. This means implement your solution one portion at a time where you compile, run, and test the code portion before moving on to the next portion. Use the provided test cases to help you arrive at your final solution. TASK 1: Study the lecture notes (Powerpoint slides and pre-recorded lectures) and assigned readings before you start. TASK 2: Replace "??" with your name, creation date, and a description of the program (synopsis). NOTE: DO NOT delete nor change the code already given to you in the code template, except for the comments /* REPLACE THIS COMMENT WITH YOUR VARIABLES */ and /* REPLACE THIS COMMENT WITH YOUR CODE */. You will insert your solution by replacing these two comments. TASK 3: Write C++ code using the while statement to repeatedly read a sequence of characters from the user using the cin statement until the user enters a period (.) or exclamation mark (!). TASK 4: Write C++ code to count the number of vowels, consonants, numeric digits, and other characters. TASK 5: Write C++ code to display statistics using the counts computed in TASK 4. • Be sure that there is a comment documenting each variable (see the document on Carmen under Modules on how to comment your code). • Do not start a variable name with a capital letter. Be sure that your code is properly indented, readable, and use good descriptive names.
