Lecture 1: Introduction to C++

• Course policies and goals
• Scheme and C++
• Basic C++ types and operations

Scheme and C++

• functional versus object-oriented
• Evaluate expressions versus execute commands
• interpreted (at least Dr. Scheme) versus compiled
• Declaration versus details
• types

Some history

• C: invented in early 1970's by K & R for Unix systems programming
• General purpose, efficient, but generally "high-level assembly"
• C++: developed by Stroustrop in early 1980s to implement OOP
• C++ grown by accretion rather than design (cf Java)

Basic things that go into C++ programming

• text editor
• text files that contain the program (source files)
• header files with declarations
• Compiler

Some simple programs

• Hello world
• Basic arithmetic expressions
• values versus locations (data, pointers, references)

C++ data types

• integer: bool,short,int,long
• floating point: float,double
• addresses of/references to any type (exposes the computer's memory to the programmer)
• arrays of any type
• structures/objects

C++ operations

• Arithmetic on numeric types
• Pointers:
  • Address, dereference operators
  • Pointer arithmetic
• Printing
  • cout,cin,cerr (C++)
  • printf (C)
