c++ - Display hex per character in the message? -


would display hex per char in message(simple way if possibe, know can loop through chars , it):

typedef struct{     double dtime;     char cmessage[11]; } typecanmessage;  typecanmessage cmmessage1 = {4.5, {0xd2, 0xf1, 0xe0, 0xf1, 0xf1, 0xf1, 0xf1, 0x23, 0x23, 0x23, 0x23}};  qmessagebox *msgbox = new qmessagebox(0); msgbox->setgeometry(qrect(qpoint(200,200),qsize(400,400))); msgbox->setinformativetext(qstring::number(cmmessage1.dtime, 'f', 8) + "  "      + qstring::number(cmmessage1.cmessage, 'x')); // <-- perhaps msgbox->exec(); 

error: "call of overloaded 'number(char[11], char)' ambiguous"

modification:

sprintf(cm, "%x", &cmmessage1.cmessage);  qmessagebox *msgbox = new qmessagebox(0); msgbox->setgeometry(qrect(qpoint(200,200),qsize(400,400))); msgbox->setinformativetext(qstring::number(cmmessage1.dtime, 'f', 8) + "  "      + (qstring)cm); // <-- perhaps msgbox->exec(); 

result: bfb123d8 //wrong


i want avoid doing following(loop or no loop):

 sprintf(cm, "%x%x%x%x%x%x%x%x%x%x%x", cmmessage1.cmessage[0],                             cmmessage1.cmessage[1],                             cmmessage1.cmessage[2],                             cmmessage1.cmessage[3],                             cmmessage1.cmessage[4],                             cmmessage1.cmessage[5],                             cmmessage1.cmessage[6],                             cmmessage1.cmessage[7],                             cmmessage1.cmessage[8],                             cmmessage1.cmessage[9],                             cmmessage1.cmessage[10]); 

looping:

for(int = 0; < 11; i++){     sprintf(cm + 2 * i, "%x", cmmessage1.cmessage[i]);  } 

the number functions format single number. if want format each number in array, you'll need loop, along lines of

auto text = qstring::number(cmmessage1.dtime, 'f', 8) + "  "; (unsigned c : cmmessage1.cmessage) {     text += qstring::number(c,16); } msgbox->setinformativetext(text); 

(you should using unsigned char, not char, store 8-bit unsigned values).
