Programming Language Statistics for IOI2000

At IOI2000, there were two competition days, with three programming tasks each (as usual). The available programming languages were: Pascal (Turbo Pascal 7.0) and C/C++ (Turbo C++ 3.0).

Only executables had to be submitted, but most competitors also left behind their source files.

The following table shows, for each task, how many executables were produced and which source files were made. The counts were obtained by counting files named task.ext, where task is replaced by the task name, and ext by `exe', `pas', `c', and `cpp'.

Notes:

• I have not attempted to infer the language from the executable (though this is feasible).
• It may happen that an executable was submitted, without source file.
• It may happen that a source file was made, but not an executable.
• It might happen that a competitor made several source files for the same task in different languages. I did not check for this.

Task.Extension	exe	pas	c	cpp	c+cpp	pas+c+cpp
palin	270	181	20	64	84	265
car	240	168	24	53	77	245
median	234	165	19	59	78	243
walls	261	178	23	61	84	262
post	284	184	24	68	92	276
block	195	145	13	43	56	201
TOTALS	1484	1021	123	348	471	1492

Here are the percentages of the languages used (relative to total number of analyzed source files):
