详解C++的String类的字符串分割实现

String recogScop = "01-02-03"; cout<<recogScop<<endl; int size = recogScop.size(); int pos = 0; string result[20] ;  for(int i=0, j=0; i<size; i++,j++ ) {   pos = recogScop.find("-", i);    if(pos == -1)   {     String subEnd = recogScop.substr(i, size - i); //最后一个字符串     result[j] = subEnd;     break;   }   if(pos >0)   {     String sub = recogScop.substr(i, pos-i);     result[j] = sub;     i = pos;   } }  for(int i=0; result[i] != ""; i++)   cout<<result[i]<<endl;
