What do you mean by "without using a temp string"? Give an example possibly...

See below example and made changes in that as per your requirement:-
this is just idea how you can do that

C++

#include<iostream>
#include<cstdio>
#include<fstream>
#include<string>

int main ()
{
    ifstream file("vowels.txt");

    char cstr[80];
    
    while (!file.eof())
    {

    file.getline(cstr,80);
    
    
    
    for(int i = 0; i < cstr.length(); i++)
    {
            if(cstr[i] == 'a' || cstr[i] == 'e' || cstr[i] == 'i' || cstr[i] == 'o' || cstr[i] ='u') 
            {
            cstr[i] = '';
            }
            else
	    {
              text[i]= putchar(toUpper(text[i]));
            }
    
    }


}

system("pause");
return 0;
}

Solution 1

Please describe what type of characters you want to remove?
I have created an application in VB.Net for specific and private use.
but, if you can describe your question then only members can help you. :)

i want to convert Lowercase to Capital letters and remove Vowels from file.for example if we have in file" abcdefo" we should change it to "BCDF". my question is how to remove these char i mean what function i use?

this is your custom need right?
so you have to create custom code for that...
a basic step is that you can run a for loop for that
for ex.
Dim iString as new TextBox 'create a vitual textstore
For Each iChar in TextBox.Text 'check each char from input
If char.isLower(iChar) Then iString.AppendText(char.toUpper(iChar)) ' checks if char is lower if yes converts to upper
Next

and for replacement just use txtInputTextBox.Replace method
or check this link "http://www.vbforums.com/showthread.php?713587-Removing-vowels-from-string"

I am not coding with any editor right now so the above code may have bugs.
its just an Idea, to how you should process.
