Program Plan Intro

Average Number of Letters

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 determine the average of number of letters and then display it.

In code window, write the code:

Program.cs:

  • Include the required libraries.
  • Define the namespace “Average”.
    • Define a class “Program”.
      • Define a constructor for the class.
      • Define required functions to run “Form1”.

Form1.cs:

  • Include the required libraries.
  • Define namespace “Average”.
    • Define a class “Form1”.
    • In btnCount() method,
      • Call countWords() method to count the number of words in a sentence.
      • Call countCharacters() method to find the average number of words in a sentence.
      • Display the count and average number of words into 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.
    • In countCharacters() method,
      • Declare the required variables.
      • Check whether string length is equal to “0. If yes, continue the execution.
      • Otherwise, calculate the word length.
      • Check whether the character is punctuation. If yes, decrement the word length.
      • Return the count of word length.
    • Close the application.
