Can I increase the size of statically allocated array?
Answer: B
Correct answer: No
A statically allocated array has its size fixed when the program is compiled, and there is no mechanism to change it at run time.
Obtaining a larger one means allocating fresh storage dynamically and copying the contents across - which is exactly what realloc does for heap blocks. This inflexibility is the principal reason dynamic allocation exists, and it is why every growable structure in C is built on the heap.
