Learning to read and write are
very essentials to everyone that’s why education is very important for every
individual in this world. Being literate is a must for us we can’t find a
better job is we were not able to finish our studies. One of the basic skills
that the school can give to the student is to know how to differentiate
consonants and vowels in the elementary level of educational learning of the
student.
This consonants and vowels are
the building blocks in any words, sentences and paragraphs that we have read,
write and most importantly understand. Our teacher during the preschool or
kinder garden levels teaches the students that vowels are those letters that
are A, E,I,O and U while the consonants are those letters that does not belong
to vowels. Having this knowledge we can build our own understanding about words,
sentences, phrases and paragraphs that we read from newspapers, books,
magazine, e-books or news over the Internet.
Being literate in terms of our
vocabulary makes us more confident person and able to express ourselves to
other people that we meet. It also help us boost our self confidence specially
in applying for a job and during the interview portion we can answer our
interviewer with ease and confidence compared to other applicants that are not
frequent or proficient with their set of vocabulary.
In this article I will discuss a
program that I wrote using Microsoft Visual Basic 6 that will accept a sentence
from the user and then it will count the number of consonants and vowels in a given
sentence. I called this program Consonants and Vowels Program, the basic
structure of our program we start with the design of our user interface that
will interact to our user. We have here a label control that will ask the user
to enter a sentence in our text box control let us named our text box control
txt_string we are applying the programming naming convention called Hungarian
Notation. After the user type the
sentence, our program has three command button the first one is called Count
when the user click the count button it will call the program to count the
number of consonants and vowels in our sentence. And then display the two label
results in our form.
I also included another command
button Clear which allows the user to clear the content of the text box and the
label in our form. It makes our user in control by allowing the user to enter a
new set of sentence that will evaluated again by our program. The third and last command button is the Quit
which gives the user an option whether the user will continue using the program
or quit and return to our windows operating system. I make our program shorter and more easier so
that everyone with a basic knowledge and understanding about programming can
easily learn by using the codes in their particular programming projects and
assignments.
Sample Output of Our Program
Quit Program Screenshot
Program Listing
Const vowels = "aeiou"
Const consonants =
"bcdfghjklmnpqrstvwxyz"
' This function will count the
number of vowels in a given sentence
Private Function
CountVowels(strText As String) As Integer
Dim i As Integer
Dim asciiToSearchFor As Integer
For i = 1 To Len(LCase(strText))
If InStr(1, vowels, Mid$(strText, i,
1), vbTextCompare) Then
CountVowels = CountVowels + 1
End If
Next i
End Function
' This function will count the
number of consonants in a given sentence
Private Function
CountConsonants(strText As String) As Integer
Dim i As Integer
Dim asciiToSearchFor As Integer
For i = 1 To Len(LCase(strText))
If InStr(1, consonants, Mid$(strText,
i, 1), vbTextCompare) Then
CountConsonants = CountConsonants +
1
End If
Next i
End Function
Private Sub cmd_clear_Click()
txt_string.Text = " "
lbl_consonants.Caption = "
"
lbl_vowels.Caption = "
"
txt_string.SetFocus
End Sub
Private Sub cmd_count_Click()
no_vowels =
CountVowels(txt_string.Text)
no_consonants =
CountConsonants(txt_string.Text)
lbl_consonants.Caption =
"The number of consonants in a sentence is
" & no_consonants & "."
lbl_vowels.Caption = "The
number of vowels in a sentence is "
& no_vowels & "."
End Sub
'Quit Procedure
Private Sub cmd_quit_Click()
Dim Response As Integer
Response = MsgBox("Are You
Sure You Want To Quit The Program", vbYesNo + vbQuestion, "Quit
Program")
If Response = vbYes Then
End
Else
Me.Show
Me.txt_string.Text = ""
lbl_consonants.Caption = "
"
lbl_vowels.Caption = "
"
Me.txt_string.SetFocus
End If
End Sub
I hope you have learned something new in this article that I
write about making a program that will count the number of consonants and
vowels in a given sentence using Microsoft Visual Basic 6.
Thank you very much
