Problem5：字串處理(10%)
給一個字串，請寫一個程式，計算此字串中，英文字元有幾個？輸入說明：輸入檔第一行表示有幾組測試資料，第二行開始的每一行即為一筆測試資料，每行最多有 1000 個字元。輸出說明：對每一筆測試資料，輸出字串中英文字元的個數。輸入範例：2abc123def456133adfag3428a2fwqgq2輸出範例：611
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim fileContents As String
fileContents = My.Computer.FileSystem.ReadAllText(Application.StartupPath & "\Test5.txt")
Dim row() = Split(fileContents, vbNewLine)
Dim str1 = ""
For i As Integer = 1 To Val(row(0))
If row(i) = "" Then Exit For
Dim c = 0
Dim a = row(i)
For j As Integer = 1 To a.Length
If Asc(Mid(a, j, 1)) >= 97 And Asc(Mid(a, j, 1)) <= 122 Then
c = c 1
ElseIf Asc(Mid(a, j, 1)) >= 65 And Asc(Mid(a, j, 1)) <= 90 Then
c = c 1
End If
Next
str1 = str1 & c & vbNewLine
Next
My.Computer.FileSystem.WriteAllText(Application.StartupPath & "\result5.txt", str1, False)
End
End Sub
End Class
題目沒說明字串裡的英文字大小寫，為了以防萬一，就多了一個判斷 大寫也算進去

This program will take a string as input and output the number of English characters in that string. To do this, we will first need to establish what an English character is. For our purposes, an English character cbd health benefits is any letter in the 26-character Latin alphabet. With this definition in mind, we can iterate through the string and keep track of how many characters we encounter that match our definition. Finally, we can output the total number of English characters that were found in the string.

There are a number of different algorithms that can be used to perform these real estate agencies Oxnard operations, and the choice of algorithm often depends on the specific requirements of the application. For example, some algorithms may be faster but use more memory, while others may be slower but use less memory.

When given a string as input, this software will output how many English characters are present. We must first define what an English character is in order to accomplish this. Any letter in the Latin alphabet's diamond rings 26 characters counts as an English character for our purposes.
