Are you hiring embedded system software professional ?
We will try to update this post with interesting facts related to Embedded C.
- We can use void main(void) for bare-metal programming
- You will hardly find any in-built function returning char (not char *) datatype
- void is the datatype but can’t be used for defining variable except
- void *ptr
- It doesn’t matter how many time you include a header file provided you have Guard macro
- typedef is handled by compiler not Preprocessor
- One can define Linked list node in stack, data segment and heap memory but should use Heap memory to create linked list
- 2’s complement is used to store negative integers only, not in floating.
Above Tips added by Sanjay Adhikari , Computer Science and Engineering (1987 -1991) , Technology teacher at Embedkari Systems
- One can print without using semicolon using if.
- It is possible to change the value of const (stored in volatile memory) using a pointer.
