Submitted by IncludeHelp, on May 24, 2018 Top Interview Questions and Answers in Embedded C. 1) What is an Embedded C? It is a combination of hardware and software. However, if the lower-priority task is using the shared resource when the higher-priority task becomes ready, then the higher-priority task must wait for the lower-priority task to finish. For all the C Questions the applicants can find the four alternatives. We can use function inside ISR as long as that function is not invoked from other portion of the code. b) file Also, if the structure is big, then passing the structure by value means copying the whole structure to the function argument stack which can slow the program by a significant amount. A pointer that is not initialized to any valid address or NULL is considered as wild pointer. This type of pointer is called dangling pointer. An ISR returns nothing because there is no caller in the code to read the returned values. 15 signs your job interview is going horribly, Time to Expand NBFCs: Rise in Demand for Talent. c) assembler b) linker c. int.
