  When using C++, you should always strive to use STL containers like std::vector and std::list instead of ordinary C arrays.
  Consider this example:
  <br /> int* array = new array[size];<br /> doSomething(array);<br /> delete[] array;
  1
  2
  3
  4
  <br />
  int* array = new array[size];<br />
  doSomething(array);<br />
  delete[] array;
  All is fine, until doSomething() is changed to throw an exception. If doSomething throws, we will have a memory leak.
  The correct way of doing this is:
  <br /> vector array(size);<br /> doSomething();
  1
  2
  3
  <br />
  vector array(size);<br />
  doSomething();
  If doSomething() throws an exception now, no memory will be leaked.
  This is just one of the reasons to use STL containers instead of C arrays. STL containers are much less error prone, more robust and easier to use.
