C and C++ information, cheatsheets and mini-projects.
Relies on https://github.com/cirosantilli/cpp-boilerplate to factor code out. See its documentation for information on how to use this project.
On Ubuntu 12.04:
./configure
make run
When there are multiple files compiled, e.g.:
c.c -> c
cpp.cpp -> cpp
run a given file by specifying the basename without extension:
make run=c
make run=cpp
The =
sign is not optional!
Doing just make run
in those cases will run the default file.
To print the generated assembly code to the screen use:
make asm RUN=cpp
To get help on all options use:
make help
Larger projects may be in separate repositories.
There may be other compiled languages here for which we don't have much material for a separate repository, specially when we interface that language with C. Ex: Fortran.
Non-portable features shall be clearly separated from portable ones in either:
- ifdef blocks
- separate files
- separate directories
- separate repositories
Everything that can be checked in an assertion will be checked, and will not get printed.
For example, a C addition operator +
test should be done as:
assert(1 + 1 == 2);
and never:
printf("%d\n", 1 + 1);
so that all can be verified automatically.
Features which yield unpredictable outputs can print results to stdout. For example, time(NULL)
printf("%d\n", 1 + 1);
Features that:
- require user input such as C
scanf
- make programs wait for perceptible amounts of time
shall be put inside a block analogous to a if (0){ ... }
to be turned on only when users want to test those specific features.
Cheat source comments are written in markdown indented by headers and commented out.
Every important keyword that one might search for in the feature has a hash before it, e.g. #function
, #include
, #printf
, etc.
