2. data types The primary data types used in Embedded C are:  int (integer), char (character), float (floating point), double (double precision floating point), along with modifiers like "unsigned" and "short" to adjust the size and range of the data depending on the specific hardware requirements; "void" is also used for functions that don't return any value. 

3. Key points about data types in Embedded C: Int :  Most commonly used for whole numbers, usually signed by default.  Char:  Represents a single character.  Unsigned:  Can be used with integer types to store only positive values, allowing for a larger positive range.  Short:  Can be used to declare smaller integer variables, often useful for memory-constrained systems.  Float/Double:  Used for decimal values, with "double" offering higher precision at the cost of more memory usage. 

4. Important considerations when choosing data types in Embedded C: Memory constraints: Microcontrollers often have limited memory, so choosing the smallest appropriate data type is crucial.  Hardware specific details: The exact size and range of each data type can vary depending on the microcontroller architecture.  Bit manipulation: Embedded systems often require direct manipulation of individual bits, which can be achieved using bitwise operators.
