c++ - 不是我要内容的地址？

Question

我只是因为在我的代码上浪费了更多时间而变得越来越困惑。我只想要迭代器的内容，而不是它的地址。这是我的代码:

Peptides tempPep;
tempPep.set_PEPTIDE("AABF");
std::vector<Peptides>::iterator itPep = std::find_if (this->get_PepList().begin(), this->get_PepList().end(),boost::bind(&Peptides::Peptide_comparison, _1,tempPep)); 
if (itPep != this->get_PepList().end()) 
{

   Spectra tempSp;
   tempSp.set_Charge(1127);
   tempSp.set_Snum(1);
   std::cout << "without iterator "<< this->get_PepList()[0].get_New_S_num() << std::endl; 
   // output -> 0
   std::cout << "with iterator" << itPep->get_New_S_num() <<std::endl;
   //output -> 1129859637
}

Answer 1

尝试将您的代码更改为以下内容:

std::vector<Peptides> p = this->get_PepList();
std::vector<Peptides>::iterator itPep = std::find_if (p.begin(),
    p.end(),boost::bind(&Peptides::Peptide_comparison, _1,tempPep));
