C malloc() arrays aren't taking up memory even after being accessed


You seem to be assuming that every call to malloc () will ask the operating system to allocate memory. That's very unlikely, especially for small allocations. You should expect allocations from the OS to be very, very rare.

Why is memory being allocated before malloc code has run?
An initial heap is allocated to the process by the OS when the process is loaded; if an allocation cannot be satisfied the heap is extended by requesting more memory from the operating system. See http://duartes.org/gustavo/blog/post/anatomy-of-a-program-in-memory/ for an explanation for example. What you are seeing is the initial heap allocation to the process, not the total memory allocated by

Misconception of how memory is created using malloc()/calloc()
It appears that you are comparing apples to oranges: When you print a[i] is at ... pointers, you show the addresses of elements inside the array a However, when you shoe the memory layout, you show the values at these addresses, which are themselves pointers, so the whole picture looks confusing.

For something a bit more reliable, if you're already using session data, you can store a flag in the session upon the user clicking the "agree" button on the terms page. Perhaps that does a f

For example, Android and iOS apps will not be approved for this permission. In addition, Web, Desktop and TV apps will not be granted this permission.
