find elements of an array in another array, why do I have this error?

I was trying to visualize the algorithm of this exercise, but I'm having a lot of problems. the exercise asks to implement this function: extern const void *mem

Is it possible to set bits of a void* value without type casting it to an int or char?

I am working on a project that requires me to allocate some space using the mmap function and I need to create a bitmap in the beginning of the allocated space.
