If I declare a data structure globally in a C++ application , does it consume stack memory or heap memory ?

For eg

struct AAA
{

.../.../.
../../..
}arr[59652323];

Since I wasn't satisfied with the answers, and hope that the sameer karjatkar wants to learn more than just a simple yes/no answer, here you go.

Typically a process has 5 different areas of memory allocated

  1. Code - text segment
  2. Initialized data – data segment
  3. Uninitialized data – bss segment
  4. Heap
  5. Stack
