2. Programming Tools

• Review: creating and running a program

• Reference
  • C basics
  • text editors
  • C++ compilation

• In-class exercise 1.1
  C++ and Python solutions to Exercise 1.1

• Streams and pipes
  • programs test1.cc, test2.cc, test3.cc
    - python equivalents: test1.py, test2.py, test3.py
  • usage: test1 | test2 | test3
  • output redirection

• In-class exercise 1.2
      C++ and Python solutions to in-class exercise 1.2.

• Simple graphics in Python
  • the matplotlib module
  • sample code: graphics.py

  • examples

• Graphics in C++
  • no built-in graphics
  • simple standalone tools: gnuplot and gpl
    - data may be read from a file (here's an example) or piped from a running program:
    

         myprogram | gpl <options>

  • more graphics tools
    • plot_data
    • gpl.py, a python version of gpl
    • making scripts executable

  • more examples

• Assembling a homework
  • create individual files using text editor, gpl, matplotlib, etc.
    

         g++ myprogram1.cc -o myprogram1
         myprogram1 | gpl [options] -P > file1.ps
    
         python myprogram2.py > file2.txt

  • convert to PDF
    

         ps2pdf file1.ps file1.pdf
    
         a2ps file2.txt -o file2.ps
         ps2pdf file2.ps file2.pdf
    
         a2ps file2.txt -o - | ps2pdf - file2.pdf
    
         a2ps myprogram1.cc -o myprogram1.cc.ps
         ps2pdf myprogram1.cc.ps myprogram1.cc.pdf
    
         a2ps myprogram2.py -o - | ps2pdf - myprogram2.py.pdf

  • assemble using acrobat, evince, pdftk, etc.
    

         pdftk file1.pdf file2.pdf myprogram1.cc.pdf myprogram2.py.pdf cat output all.pdf

  • a sample script
