Program Plan Intro

Removing all the punctuations from a string

Program plan:

• Create a class StringBuilder to remove all the punctuation stored in a string.
  • In main() function,
    • Initially, assign the original string in variable.
    • Then, invoke the removeIt()function to remove all the punctuation in a string and store the final value in original string.
    • Display the string after removing the punctuation in console screen.
  • In the method removeAt(),
    • It passes  input parameter “s” to check whether the character contains punctuation in the string. If yes, then it removes all the punctuation stored in the string “s”.
    • For loop read all the characters from a sentence until the condition leads to false.
    • Then, it calls the function ok() and check whether the character at “j” position matches with the character or not.
      • If the result returns the Boolean value false, then delete the character at the specified position in “j” otherwise store the character using Tostring() method in “s” variable.
  • In the method ok(),
    • It passes input parameter “i” to check whether the character in the sentence matches with the corresponding ASCII values.
      • If yes, then it returns the Boolean value true otherwise it return false.
