ifstream for Input Stream for a File. Also remember that ifstream in


in.open("oldfile.txt");
This takes as Parameter old string that means quotations. Which means that
string s = "oldfile.txt";
in.open(s) will give us an error

To fix this problem use s.c_str() function instead of s as the parameter, This
converts it into the old string

Some Discussions about Object Oriented Programming. The Next Big Thing.

Scanner Class was discussed. In Visual C++ while creating a new object there is

no need for the new operator.

What are Container Classes?

CS106B Vector class has a built in Better Array

Bounds Checking
Add, Insert, remove
Memory Managemet, knows its size

Vector Class as a template. Vector decribes what it is storing using a place holder. Example:
template ElemType>

class Vector {
public:
addObject ( ElemType value);
}
