THE PRE-PROCESSING
- Inclusion of header filesMacros
- Assembly macros, volatile vs non-volatile
registers

STATEMENTS
- Selective statements : if...else, ternary
operator, switch...case
- Iterative statements : while(),
do...while(), for()
- Control statements : break, continue,
return
POINTER AND ARRAY
- Addressing modes of the ARM core
- Position independent code and data

in memory
STRUCTURE AND UNION
- Structure : declaration, initialisation,
access to fields, nested structures

DYNAMIC ALLOCATION AND LINKED LISTS
- Benefit of the heap compared to static
data sections
- Related functions : malloc(), calloc(),
realloc() and free()
- Description of the memory allocation
first fit algorithm
