我试图从多个向量中打印出每个向量中的所有元素.构建失败但错误发生在头文件中的某个地方,恐怕我根本不理解错误代码.任何帮助将不胜感激!这是错误:

error: invalid conversion from 'const std::basic_string<char, std::char_traits<char>, std::allocator<char> >* const' to 'std::basic_string<char, std::char_traits<char>, std::allocator<char> >*'

以下是导致问题的代码.

multiset<vector < string > > setOfRules;
vector<string> testing,testing2;

testing.push_back("bar");
testing.push_back("foo");
testing2.push_back("foo2");
testing2.push_back("bar2");
setOfRules.insert(testing);
setOfRules.insert(testing2);

for (multiset< vector <string > >::iterator myIterator = setOfRules.begin();
     myIterator!=setOfRules.end(); 
     ++myIterator) 
{

    for (vector< string >::iterator myOtherIterator = ( *myIterator ).begin(); 
         myOtherIterator != ( *myIterator ).end(); 
         ++myOtherIterator) 
    {
        cout << *myOtherIterator << " " ;
    }
    cout << endl;
}
