Problem uisng QTextStream

[Arshia Aghaei]

The signed 32 bit integer -1073741510 is 3221225786 when treated as an unsigned 32-bit integer, and 0xC000013A in hex.
That code means, STATUS_CONTROL_C_EXIT {Application Exit by CTRL+C} The application terminated as a result of a CTRL+C.

The likely reason you get no output is because the QTextStream is buffered and you have done nothing to trigger an immediate flush.
See QTextStream::flush() or the flush stream manipulator.

I don't want to use QTextStream::flush() or QTextStream::endl() , i want to get the input at the same line with the prompt ...
What should i do then ?

Using QTextStream::flush() won't cause the output position to move to a new line, but it will force the output to be displayed on stdout, which I believe is what you want to occur.
