The example files
You will find among the files a lot of programs named
ex1.c,ex2.c,...
They contain examples of programs contained
in the present manual in order to show you several things that
can be done and how they should be done, but they also serve for big tests of
the system.
To some of these programs
there corresponds an input file
ex*.in
which contains a possible input for the corresponding program.
How you can apply these
examples will be described in the following chapter. But if you are
impatient you may right now play with these examples in the following
way:
- Replace the file test.c by any one of these example files, say by
ex1.c and
- enter make
The system will then either tell you that a.out is ready, or, after
a while the prompt will return and then you simply enter
a.out
and either the program will immediately run (depending on the example used),
or you will be asked for parameters to enter. For example, if test.c
equals the example ex1.c, then you will be asked for an integerobject, and
if you enter 5, say, it will return you the number 5 which you
have entered.
Here are a few descriptions of some of the easier example files which you
may now like to play with:
- [ex4.c] This program shows you how easy it is to evaluate a character table
of a symmetric group of given degree, and how a particular character value can
be calculated.
- [ex6.c] This program evaluates a matrix the entries of which are
the scalar products of the Young characters of the symmetric group of given
degree.
- [ex16.c] Here you can see how the character table of a wreath product of
symmetric group can be obtained.
- [ex17.c] This example shows how decomposition matrices and matrices
of irreducible Brauer characters of symmetric matrices
can be evaluated.
