   In little-endian format, the least significant byte is stored at the highest memory address.

2. B

   In little-endian format, the most significant byte is stored at the lowest memory address.

   Stack memory is used for storing global variables, while heap memory is used for storing local variables.

2. B

   Stack memory is automatically managed for function calls, while heap memory requires explicit allocation and deallocation.

3. C

   Stack memory can grow indefinitely, while heap memory has a fixed size defined at compile time.

4. D

   There is no difference; stack and heap memory serve the same purpose in C programming.

   A static variable inside a function retains its value between function calls.

2. B

4. D

   A static function can be called from other files of the same program.

1. A

   A pointer can be incremented to point to the next memory location of its type.

2. B
