Simple c++ exercise to strings and list. The program is explained at: main page

  1. #include <iostream>
  2. #include <fstream>
  3. #include <string>
  4. #include <list>
  5. using namespace std;
  7. list<string> or_q;
  9. int main ()
  10. {
  12.   or_q.push_back("IP_");
  13.   or_q.push_back("VHDL_IP_Stack1111");
  15.   if(or_q.empty()) {
  16.     cout<<"error and q is empty" << endl;
  17.     return 1;
  18.   }
  20.   list<string>::iterator it;
  21.   string st;
  22.   fstream infile;
  23.   infile.open ("1", ios::in);
  24.   while(getline(infile,st))
  25.   {
  26.     getline(infile,st);
  27.     for(it=or_q.begin(); it != or_q.end(); it++) {
  28.       string::size_type pos = st.find(*it);
  29.       if(pos != string::npos) {
  30.         cout << pos << " match " << *it << " " << st << endl;
  31.       }
  32.     }
  33.   }
  34.   infile.close();
  35. }
