Intro To Vectors

• Some of the examples in this section use vectors.
• So we will do a quick overview.
• Vectors are dynamic one dimensional arrays.
• They are part of the standard library.
• A reference.
  • Templated, so any data type with copy constructors and assignment operators.
  • Many member functions.
  • We care about
    • push_back, pop_back.
    • [] and at.
      • Look at the at function.
      • It throws an std::out_of_range if pos>= size();
