# KNK
Programming exercises for KN King's book _C programming - a modern approach_.
## Pre 359
Compile `*.c` files with:
```shell
export BASENAME=
gcc -Wall -Wextra -std=c99 ${BASENAME}.c -o ${BASENAME}.bin
```
Then run the binary with:
```shell
./${BASENAME}.bin
```
## Post 359
Makefiles are introduced at 359. Compile subsequent projects with:
```shell
make
```
The above command should generate an executable file, e.g. `program`, which can then be run as follows:
```shell
./program
```
Clean up the tree with:
```shell
make clean
```
## Post 45607
`CMakeLists.txt` files are introduced at 45607. Compile subsequent projects with:
```shell
mkdir build
cd build
cmake --build .
cmake --install .
# run the resulting program with:
./dist/bin/program
```
## Formatting with `clang-format`
`clang-format` formats *.c files (as well as other formats), is customizable, and can inherit
from existing published style guide, e.g. Google, LLVM, etc. See
https://clang.llvm.org/docs/ClangFormatStyleOptions.html.
```shell
# print warnings, don't change files
clang-format -Werror --dry-run main.c
# print main.c to stdout including changes,
# but don't change main.c itself
clang-format main.c
# change file in-place
clang-format -i main.c
```
## Debugging with Valgrind: memcheck
`valgrind` can help detect various kinds of errors. By default it runs `memcheck`, which detects memory errors:
```shell
$ valgrind ./program
$ valgrind tool=memcheck ./program
$ valgrind --tool=memcheck --leak-check=full --show-leak-kinds=all ./program
```
To have Valgrind output the relevant line numbers, recompile the binary with `-g` flag ("include debugging information")
and `-O0` ("disable optimization"). Note that this requires recompiling the objects as well.
See https://valgrind.org/ for more information.
## Debugging with Valgrind: cachegrind
\# TODO
## Debugging with Valgrind: callgrind
\# TODO
## Other
- https://cdecl.org/ for decoding declarations

Have `gcc` generate Assembler code
```shell
gcc -c -S main.c # generates main.s
```
Printing the shared objects (shared libraries) required by each program or shared object specified on the command line:
```shell
ldd program
```
List the symbols from an object file:
```shell
nm main.o
```
