How to Compare Characters ASCII value?

[munna]

use toAscii to get 8-bit ASCII representation of the string

Thanks 4 d reply, It returns an 8-bit ASCII representation of the string,
but how can i compare this , that the ASCII values is between [0-31] or not.

Pls explain it with me example

You may very well write ur own function for that -

void removeDirtyChars(QString &input)
{
    QByteArray asciiInput = input.toAscii();
    input.clear();
    for(int i=0;i<asciiInput.length();i++)
    {
        if(asciiInput.at(i)  is not between [0-31]    // You logic to determine which chars u want
            input += asciiInput.at(i);
    }
}

void removeDirtyChars(QString &input)
{
    QByteArray asciiInput = input.toAscii();
    input.clear();
    for(int i=0;i<asciiInput.length();i++)
    {
        if(asciiInput.at(i)  is not between [0-31]    // You logic to determine which chars u want
            input += asciiInput.at(i);
    }
}

To copy to clipboard, switch view to plain text mode 

Hope u get the logic

Thanks for d reply, I got the logic, but there is a confusion in a line

if(asciiInput.at(i) is not between [0-31]  You logic to determine which chars u want

if(asciiInput.at(i) is not between [0-31]  You logic to determine which chars u want

To copy to clipboard, switch view to plain text mode 

I want to compare all the characters whose ASCII value lies between [0-31], how can i do this, Is I have to compare ASCII value one by one or is there any other logic

Thanks all my problem is solved.
