Week 03 Notes for CS 1500 -- Fall 2004

• Take roll.
• Check schedule
• Announcements
  • (Revised) tutoring hours.
  
  
• Discuss compiling/debugging with jove
  • How to execute the compiler "inside" jove:
    
    C-u, C-x,C-e
    
    then erase "make" by doing C-h four times, then type the compiler command such as
    
    g++ p1.cpp
    
    
  • C-x 1 "unsplits" the screen.
  • How to break out of jove to a sub-shell whilst "saving your place": (esc-s)
  • Testing the program while in the sub-shell.
  • How to break out of the sub-shell and return to "your place" in jove: (exit)
  
  
• Note that using JOVE as above makes debugging go easier.
• If interested, you can read the compileHelp document for more information about using JOVE for compiling and debugging. This document is in the General_Info section of the class web space.
• Each Sun is equivalent to the others.
• Discuss simple C++ constructs
  • use of cout stream
  • Using string expressions with cout <<
  • Using arithmetic expressions with cout <<
  • use of endl
  • using functions -- good for parts of programs that have to be repeated.
  
  
• Look at the sample program of lab #1 -- illustrate the type of work that the students will do:
  • Compile and run a copy of the program.
  • Stash a copy of the resulting output.
  • Inserting a comment and alter the "cout" statements slightly.
  • Compile and re-run the program.
  • Notice where the new output is different, and where not different.
  
  
• Discussion of solo program #1 -- look at the things in the assignment directory and use them to help give a description of what the solution to the assignment problem will "look like."
  
  
• Discussion of sample programs and the new programming concepts they illustrate.
  • use of cout stream (e.g. ex0201.cpp)
  • Using expressions with << (e.g. ex0201.cpp)
  • use of endl (my_example.cpp)
  • using functions (my_example.cpp)
  • int's versus float's
  • declaring and naming variables (e.g. ex0201.cpp, ex0202.cpp, ex0205.cpp)
  • assignment statements, lvalues, rvalues (e.g. ex0201.cpp, ex0205.cpp)
  • separate and combined declaration-initialization (e.g. ex0205.cpp)
  • integer arithmetic -- including surprises about integer division (e.g. ex0205.cpp)
  • modulus operator % and unary - (e.g. ex0205.cpp)
  • operator precedence (my_example.cpp)
  • interactive programs (e.g. ex0220.cpp)
• Demonstrate some tasks that will be needed in lab #2. (Mainly these are the things seen in boldface above.)
