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;
