WebApr 22, 2024 · Top 10 Embedded C Frequently Asked Questions What do you mean when you say "embedded system"? What is the C stack overflow error? What does "interrupt latency" mean to you? Can a variable in C be volatile and constant at the same time? What are some examples of embedded processors' Real-Time applications? When you create the structure the compiler may insert some extra bytes between the members of the structure for alignment. These extra unused bytes are called padding bytes and this technique is called structure padding in C. Structure padding increases the performance of the processor at the penalty of memory. If … See more Output:12 In the above declaration, Integer is the largest structure member (4 bytes) so to prevent from the penalty compiler inserts some extra padding bytes to improve the … See more Output:8 In the above example, the size of the InfoData is 8 bytes due to 2 tail padding bytes inserted by the compiler for the data alignment. See more Output:16 The largest structure member is int (4 bytes), hence the compiler aligned the memory in the form of 4 bytes. See more Output:16 The largest structure member is double (8 bytes), hence the compiler aligned the memory in the form of 8 bytes. So here compiler adds 6 padding bytes for the alignment, and the … See more mercury h81 motherboard drivers
