For QStrings there is a toInt( ) (or toDouble( ), etc) function that will convert the string to the appropriate number.

To convert a number into a string, there is a static function QString::number( int num, int base ) http://doc.trolltech.com/4.1/qstring.html#number that returns a QString.

But I want Encoding of QString to number as

If I have a QString like QT CENTER then it will encode it to something like 275161967.

What kind of encoding would you like to use?

[vishal.chauhan]

Any type of encoding.

It should be simple or complex.

How did you compute that number for QT CENTRE?
For a given char you can get its unicode code with QChar::unicode();

Maybe you can use that unique value to build a number from a string.

Try to search in the Internet about hashing. If you want to encode it into one integer, try CRC32 algorithm. Remenber, that hashing is irreversible...
