Chapter 8, Problem 1PP
Program Plan Intro
Word Counter
Program plan:
Design the form:
- Place a two label box controls on the form, and change its name and properties.
- Place a one text box control on the form, and change its name and properties to get the string from user.
- Place a one command button control on the form, and change its name and properties to count the word in a string and then display it.
In code window, write the code:
Program.cs:
- Include the required libraries.
- Define the namespace “WordCounter”.
- Define a class “Program”.
- Define a constructor for the class.
- Define required functions to run “Form1”.
- Define a class “Program”.
Form1.cs:
- Include the required libraries.
- Define namespace “WordCounter”.
- Define a class “Form1”.
- In btnCount() method,
- Call the countWords() method and then display the count of words in label box.
- In countWords() method,
- Declare the required variables.
- Check whether “i” is equal to “0” and any white space in a sentence. If yes, set the word beign.
- Otherwise, check whether “i” is greater than “0” and any white space in a sentence. If yes, set the word beign.
- Check whether the word begin is set and check the word is digit or letter with correct punctuation. If yes, increment the counter value by “1”.
- Return the number of words.
- Close the application.
Form Design:
View the Form Design in IDE.
Set the Form Control properties in Properties window as follows:
Object | Property | Setting |
Form1 | Text | Program8_1 |
label1 | Text | Enter a string: |
textBox1 | Text | (Empty) |
lblResult | Text | (Empty) |
btnCount | Text | Count Words |
- Add two label box controls to the form from Toolbox.
- Add one text box control to the form from Toolbox.
- Add one command button control to the form from Toolbox.

Vowels and Consonants Create an application with a method that accepts a string as an argument and returns the number of vowels that the string contains. The application should have another method that accepts a string as an argument and returns the number of consonants that the string contains. The application should let the user enter a string, and should display the number of vowels and the number of consonants it contains.
Word Separator Create an application that accepts as input a sentence in which all the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example, the string "StopAndSmellTheRoses." would be converted to "Stop and smell the roses."
C# Write a method that accepts a string as an argument and displaysits contents backward. For instance, if the string argument is"gravity" , the method should display "ytivarg"

- Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.arrow_forwardQ: People often forget closing parentheses when entering formulas. Write a program that asks the user to enter a formula and prints out whether the formula has the same number of opening and closing parentheses. Q: Write a program that asks the user to enter a word and prints out whether that word contains any vowels. Q: Write a program that asks the user to enter a string. The program should create a new string called new_string from the user’s string such that the second character is changed to an asterisk and three exclamation points are attached to the end of the string. Finally, print new_string. Typical output is shown below: Enter your string: Qbert Q*ert!!! Q: Write a program that asks the user to enter a string s and then converts s to lowercase, removes all the periods and commas from s, and prints the resulting string.

The method should determine if the string begins with an uppercase letter and ends with a punctuation mark. The method should return true if the string meets the criteria; otherwise, it should return false.arrow_forward

Pass the user’s entry to one of two overloaded GetFlightInfo() methods, and then display a returned string with all the flight details. For example, if 201 was input, the output would be: Flight #201 AUS Austin Scheduled at: 0710 (note that there should be two spaces between 'Austin' and 'Scheduled'). The method version that accepts an integer looks up the airport code, name, and time of flight; the version that accepts a string description looks up the flight number, airport name, and time. The methods return a message if the flight is not found. For example, if 100 was input, the output should be Flight #100 was not found. If no flights were scheduled for the airport code entered, for example MCO, the message displayed should be Flight to MCO was not found.

- Name format: You must use String object and not StringBuffer or StringBuilder. Many documents use a specific format for a person's name. Write a program that take one Line as an input. Example: Scanner input = new Scanner(System.in); System.out.println(“Enter firstName middleName lastName separated by at least one blank, It may have more than one blank separating firstName middleName lastName."); Input sample : Pat Silly Doe || Note these are separated by at least one blank. String line = input.nextLine() Ex: If the input is: Pat Silly Doe the output is: Doe, P.S. If the input has the form: firstName lastName the output is: lastName, firstInitial. Ex: If the input is: Julia Clark the output is: Clark, J. Please submit the .java source file and the sample run in a text file. Thanksarrow_forwardRandom Number Guessing Game Create an application that generates a random number in the range of 1 through 100 and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high, try again.” If the user’s guess is lower than the random number, the program should display “Too low, try again.” If the user guesses the number, the application should congratulate the user and then generate a new random number so the game can start over. Optional Enhancement: Enhance the game so it keeps count of the number of guesses that the user makes. When the user correctly guesses the random number, the program should display the number of guesses.arrow_forwardThis string method returns true if a string contains only numeric digits and is at least onecharacter in length.1. the digit method2. the isdigit method3. the numeric method4. the isnumber methodarrow_forward
