Final answer:

To create an array on the stack, you declare it within a function's scope without using memory allocation functions. The size must be known at compile-time and the array is automatically destroyed when the function returns.

Step-by-step explanation:

To create an array on the stack with automatic storage class, you declare the array within the scope of a function without using any memory allocation functions such as malloc or new. The size of the array must be known at compile-time, and cannot be dynamically sized at runtime. Here's a simple example in C/C++:

void myFunction() {
int myArray[10]; // Declares an array of 10 integers on the stack.
// You can now use myArray here.
}

The array myArray will be automatically created on the stack when myFunction() is called, and it will be destroyed when myFunction() returns, releasing the memory used by myArray.
