Define local variable array size too large error

  If the defined local variable array size is too large, the compiler will error "Stack Overflow".
  An array is declared inside a function, which is a local variable, stored on the stack, if the array is too large, such as a[1000000]. The amount of memory that the array occupies is: 1000000*4byte is approximately equal to 4M. The default memory space of the stack is around 1M, so it can cause memory overflow to solve this problem.
To solve this problem, you can declare an array on a global store or on a heap
  Method One: Declare the global variable
  Method Two: Store on the heap
