    Understanding creation of destruction and creation of data types

    In my book it says "We can apply static to a local array declaration so the array is not created and initialized each time the function is called and the array is not destroyed each time the function is exited in the program."


    When an array is created where exactly is the creation taking place? In the ram?

    Yes, variables are created "in memory", which is almost always the RAM.

    Where exactly in RAM variables are created varies. "Normal" or automatic variables, for example (variables that you declare normally inside of a function), are created on the stack, and are of course destroyed when the function exits. Static and global variables are created somewhere else, in memory that is only initialized once (when the program starts) and destroyed once (when the program exits). Dynamically allocated variables (malloc()'d ones) are created on the heap, and persist until they are freed manually (by calling free()).
