Count occurrences of a character in a string


Tag : vb6 , By : fayoh

it helps some times Looking for the best way to do this in VB6. Typically, I would use this approach... , I would use a modified bucket sort:
Dim i as Integer
Dim index As Integer
Dim count as Integer
Dim FoundByAscii(0 To 255) As Boolean
For i = 1 To Len(text)
    index = Asc(Mid$(text, i, 1))
    FoundByAscii(index) = True
Next i
count = 0
For i = 0 To 255
    If FoundByAscii(i) Then
        count = count + 1
    End If
Next i
   ' count spaces
    Dim asciiToSearchFor As Integer
    asciiToSearchFor = Asc(" ")
    For i = 1 To Len(text)
        If Asc(Mid$(text, i, 1)) = asciiToSearchFor Then count = count + 1 
    Next

Count occurrences of character in string c++?

This might help you Your code is counting characters when it should be counting substrings instead, eg:
#include <iostream> 
#include <string>
#include <conio.h> 

int main() 
{ 
    std::string a, b; 
    int count = 0; 

    std::cout << "Enter 1st String: "; 
    std::getline(std::cin, a); 
    std::cout << "Enter 2nd String: "; 
    std::getline(std::cin, b);

    std::string::size_type i = a.find(b);
    while (i != std::string::npos)
    {
        ++count;
        i = a.find(b, i+b.length());
    } 

    std::cout << "Output: " << count; 

    getch(); 
    return 0; 
} 

Count all occurrences of a character except at the end of the string

Does that help Replace + which exists after e with negative lookahead. e+ matches one or more e's , so regex engine should consider eee as single match. And a negative lookahead after e, ie e(?!$) helps to find all the e's but not the one which exists at the end of a line.
int count = 0;
String text = "sentence";
Pattern pat = Pattern.compile("e(?!$)");
Matcher m = pat.matcher(text);
while (m.find()) {
        count++;
}
System.out.println(count);

Count the occurrences of each character in a string

I wish this helpful for you I tried googling some information about this, but I only found some on how to count the occurrences of a pre-defined pattern of a char/string to be searched. I just mixed some of the information I learned from some tutorials/forums I've visited. , This code counts how many times each character appears in a string:
Sub Main()
    Dim text As String = "some random text"
    Dim charactersInfo = text.GroupBy(Function(c) c).ToDictionary(Function(p) p.Key, Function(p) p.Count())

    For Each p In charactersInfo
        Console.WriteLine("char:{0}  times:{1}", p.Key, p.Value)
    Next

    Console.ReadLine()
End Sub
