WEEK02
May 17 and May 19

This page contains lectures, examples and assignments for week 2 of the class "Introduction to Scientific Programming".

Lectures

• Lecture #3, First C++ Programs.
• Lecture #4, Arithmetic, Logic, Integration.

Example Programs:

• add_ints.cpp, a program which gets two integers from the user and adds them.
• add_small.cpp, a program which sets X = 1.23456789, asks the user for a Y value, and prints out X+Y to 12 digits. You may be interested to try Y = 1, 0.1, 0.01, 0.001, and so on. Eventually, Y becomes too small to make any difference to X.
• circle.cpp, a program which accepts coordinates (x,y) from the user, and reports whether that point is inside the unit circle.
• formula.cpp, a program which uses three integer variables, but which gives each one a value in a different way.
• formula2.cpp, a version of formula.cpp in which variable y is used before it has been given a value.
• gnu_input.txt, commands to GNUPLOT to create a plot.
• hello.cpp, a program which says "Hello, world!".
• precedence.cpp, a program which looks at how the rules of operator precedence are applied, and how parentheses can override those rules.
• sine_table.cpp, a program which prints out a table of values of 501 X between 0 and 20, and the corresponding sines.
• sine_table.png, a plot of the data.
• sine_table.txt, a table of sine values.
• surface_grid.cpp, a program to generate the surface plot data.
• surface_grid_gnuplot.txt, X, Y, Z data for Gnuplot.
• surface_grid_input.txt, commands to Gnuplot to make a plot.
• surface_grid.png, the surface plot.

Assignments:

• Tuesday: Read Chapter 2.1 to 2.4
• Tuesday: There will be an in-class exercise.
• Thursday: Read Chapter 2.5 to 2.8
• Thursday: There will be a programming homework assignment.
