compare qstring...

I search a similar QString function from php strcmp
http://php.net/strcmp to find the nummer on 2° position from a qmap...

How make this...

Example ... if your name is "zumalli" the formula take only the first 3 lovercase letter
"zum" and i musst return 993

if Your name is "zcello" take zce and from compare alphabet position i must return 979


Qt Code: 
  1. typedef QMap<int, QStringList> TableAi;
  2. TableAi Box_att;
  3. Box_att.clear();
  4. ................................................
  5. Box_att.insert(875,QStringList() << "x" <<  "975");
  6. Box_att.insert(876,QStringList() << "z" <<  "976");
  7. Box_att.insert(877,QStringList() << "zam" <<  "977");
  8. Box_att.insert(878,QStringList() << "zau" <<  "978");
  9. Box_att.insert(879,QStringList() << "zb" <<  "979");
  10. Box_att.insert(880,QStringList() << "ze" <<  "980");
  11. Box_att.insert(881,QStringList() << "zeh" <<  "981");
  12. Box_att.insert(882,QStringList() << "zei" <<  "982");
  13. Box_att.insert(883,QStringList() << "zem" <<  "983");
  14. Box_att.insert(884,QStringList() << "zf" <<  "984");
  15. Box_att.insert(885,QStringList() << "zi" <<  "985");
  16. Box_att.insert(886,QStringList() << "zim" <<  "986");
  17. Box_att.insert(887,QStringList() << "zin" <<  "987");
  18. Box_att.insert(888,QStringList() << "zk" <<  "988");

  22. Box_att.insert(892,QStringList() << "zul" <<  "992");
  23. Box_att.insert(893,QStringList() << "zum" <<  "993");
  24. Box_att.insert(894,QStringList() << "zun" <<  "994");
