C++ (Cpp) Cont::back Examples

Example #1

File: pool_test.cpp Project: alexeevm/voltdb

void updateContainer(Cont<T, Alloc>& cont) {
   // flip a coin to determine using emplace_back() with 80% of likelihood, or pop_back() with 20% of likelihood.
   static std::bernoulli_distribution dist(.8);
   if (cont.empty() || dist(S1::s_gen)) {
      cont.emplace_back();
   } else {
      cont.pop_back();
   }
   // and with 20% likelihood mutating 1st and last elem's std::string field
   if (!cont.empty() && !dist(S1::s_gen)) {
      cont.front().m_str.append("- foo");
      cont.back().m_str.append("- bar");
   }
}

Example #2

File: main.cpp Project: mdaughtrey/personal-projects

void strategy1()
{
    int numElems;
    cin >> numElems;
    Cont container;

    for (int ii = 0; ii < numElems; ii++)
    {
        container.push_back(0);
        cin >> container.back();
    }
    for (int day = 0; ; day++)
    {
        list<ContIter> toDelete;
        ContIter iThis(container.begin());
        ContIter iPrev(iThis);
        iThis++;
        while (iThis != container.end())
        {
            if (*iThis > *iPrev)
            {
                toDelete.push_back(iThis);
            }
            iThis++;
            iPrev++;
        }
        if (toDelete.empty())
        {
            cout << day << endl;
            break;
        }
//        cout << "toDelete ";
 //       dump(toDelete);
        for (list<ContIter>::reverse_iterator iDel = toDelete.rbegin(); iDel != toDelete.rend(); iDel++)
        {
            container.erase(*iDel);
