string

• Declaration
• Concatenation
• Operator overloading
• Functions
• length
• find
• insert
• c_str

7
vector

• An array-like container class
• include ltvectorgt
• vectorltelt-typegt name(size)
• vectorltintgt myints(5)
• vectorltstringgt mystrings(10)

8
vector cont.

• Can access vector elements like array
• myints2
• Functions
• at(index) -- myints.at(2) returns item at
  position 2better than because of bounds
  checking
• size() -- returns total size of vector
• front() -- returns first element (at position 0)
• back() -- returns last element at position size-1
