Howq to get the ascii of a char ?

[wysota]

Maybe something like this:

int val = 123;
int rest;
int digit;
rest=val;
QVector<char> v;
while(rest>0){
  digit = rest % 10; // last digit
  rest = rest / 10;
  v.push_front(digit+'0');
}

int val = 123;
int rest;
int digit;
rest=val;
QVector<char> v;
while(rest>0){
  digit = rest % 10; // last digit
  rest = rest / 10;
  v.push_front(digit+'0');
}

To copy to clipboard, switch view to plain text mode 

Then if you want their hex value, just sprintf them with "%x" formatting, like:

for(QVector<char>::const_iterator it = v.begin(); it!=v.end(); ++it){
  ::snprintf("%x",  *it);
  qDebug(qPrintable(hex));
}

for(QVector<char>::const_iterator it = v.begin(); it!=v.end(); ++it){
  ::snprintf("%x",  *it);
  qDebug(qPrintable(hex));
}

Of course you can use QString::arg() for that.

You can also use QString methods directly like so:

int val = 123;
QString text = QString::number(val);
QStringList hex;
for(int i=0;i<text.size();i++){
    hex << QString::number(text[i].toAscii(), 16);
}

int val = 123;
QString text = QString::number(val);
QStringList hex;
for(int i=0;i<text.size();i++){
    hex << QString::number(text[i].toAscii(), 16);
}
