Welcome to CISC181

Please take out a sheet of paper and write on it:

(1) Your full name

(2) Your ud login (e.g. the username you use to login to strauss,
    or for your ud email, or WebCT )

(3) Yes or no: have you programmed on strauss before (e.g. in CISC105?)

(4) What editor do you already know: vi or emacs?  Or neither?

(5) What was your most recent programming class? 
    e.g. CISC105 05F is probably the most common answer
    if it was something else, what programming language did you use?
     e.g. C, C++, Java, Visual Basic



=====================================
You should already be familiar with:

 (1) Assignment statements
           x = 3;

 (2) Variable declaration
         int x;

    give a type then the name of a variable
      double, char, float, FILE *, bool, 

 (3) Loops

      for, while

 (4) Selection
      if/then/else    switch/case

 (5) Function definitions
      parameter passing

 (6) Arrays


Basic input and output in C++


 (1) input and output of int, float, double
    See programs readInt.cc, readInt2.cc readInt3.cc

Next time we'll go over some of the following...
   
 (2) input and output of int arrays
    (a) from the keyboard
    (b) from a file
    (c) read from a file and find the sum
 (3) input and output strings


A few more notes:

The C++ compilers on strauss are:

  g++ and CC

You should know both... switch between the compilers
when you have error message you don't understand,
and to make sure you don't have a program that
just "happens  to work" (e.g. with an uninitialized
variable) but breaks when you use the other compiler.

cin is for input
cout is for output


<<  when used with cout
    is called the stream ____ operator

>>  when used with cin
    is called the stream _____ operator

(That, as a fill-in-the-blank question,
could show up on the 1st midterm exam)
ANS:

     
<<  when used with cout
    is called the stream insertion operator

>>  when used with cin
    is called the stream extraction         operator
