Multi dimensional arrays have more than one subscript variables.
Fortunately, these problems are easily addressed via dynamic memory allocation. Dynamic memory allocation is a way for running programs to request memory from the operating system when needed. On modern machines, the heap can be gigabytes in size.
Dynamically allocating single variables To allocate a single variable dynamically, we use the scalar non-array form of the new operator: The new operator creates the object using that memory, and then returns a pointer containing the address of the memory that has been allocated. How does dynamic memory allocation work?
Your computer has memory probably lots of it that is available for applications to use. When you run an application, your operating system loads the application into some of that memory.
This memory used by your application is divided into different areas, each of which serves a different purpose. One area contains your code. Another area is used for normal operations keeping track of which functions were called, creating and destroying global and local variables, etc….
However, much of the memory available just sits there, waiting to be handed out to programs that request it. If it can fulfill this request, it will return the address of that memory to your application.
From that point forward, your application can use this memory as it wishes. When your application is done with the memory, it can return the memory back to the operating system to be given to another program. Unlike static or automatic memory, the program itself is responsible for requesting and disposing of dynamically allocated memory.
For single variables, this is done via the scalar non-array form of the delete operator:Introduction to C Programming Arrays Overview. An array is a collection of data items, all of the same type, accessed using a common name. A one-dimensional array is like a list; A two dimensional array is like a table; The C language places no limits on the number of dimensions in an array, though specific implementations may.
