You might also want to investigate std::deque - this allocates storage as a linked list of blocks, meaning that new allocations don't require relocation of existing elements.

All the memory for a deque is contiguous

#include <deque>
#include <iostream>

int main(int, char**)
{
   std::deque<char> x;

   x.resize(10);
   if (&x.back()-&x.front() == std::distance(x.begin(), x.end())-1)
   {
      std::cout << "x is contiguous\n";
   }
   else
   {
      std::cout << "x is not contiguous\n";
   }

   x.resize(1e6);
   if (&x.back()-&x.front() == std::distance(x.begin(), x.end())-1)
   {
      std::cout << "x is contiguous\n";
   }
   else
   {
      std::cout << "x is not contiguous\n";
   }
}

x with 10 elements is contiguous
x with 1000000 elements is not contiguous

When I started C++ I used MFC. I found CString a doddle to use sadly it turned out to be not exactly the finest of string implementations.

Has this been resolved in the WTL or should I stick with the STL string or lower level self made implementations?

#include <algorithm>
#include <vector>

struct Mark
{
   int mark;
   int studentCode;
};

bool operator<(Mark const& left, Mark const& right) { return left.mark < right.mark; }

int main(int, char**)
{
   std::vector<Mark> marks;
   // Populate marks
   std::sort(marks.begin(), marks.end());
