How to print unsigned character

chandradeo

Hi frnds i get a network packet in which hour,min and second values are sent. The type of these values are indicated as UNSIGNED CHAR. When i read the data in a char array and display it in gui like this

@ udpSocketRxCDP->readDatagram(buffer, sizeof(buffer));
ui->textEditsec->setText(buffer[2]); // second @

it displays some different thing means it is not the second value.

Can anybody tell me with explanation how should i get the correct value. Thank u all in advance

chars, as the name suggests, are treated as characters. So it probably prints a nice letter for you :) Use this instead:
@
ui->textEditsec->setText(QString::number(buffer[2]));
@

Hi sierdzio thank u for ur reply. As i the buffer is a character array QString::number() doesnt takes character array as its argument as i have seen here "Your text to link here...":http://qt-project.org/doc/qt-5/qstring.html#number.

Hi,

You can type cast it as a quint8 before converting

Hope it helps

can you tell me how to type cast unsigned char to quint8?

unsigned char c = 0x55;

quint8 q = quint8(c);

But that's very basic C++...
