| | Array - Wikipedia, the free encyclopedia |
 | | Dynamic arrays or growable arrays are arrays which automatically perform this resizing as late as possible, when the programmer attempts to add an element to the end of the array and there is no more space. | | | In computer programming, an array, also known as a vector or list (for one-dimensional arrays) or a matrix (for two-dimensional arrays), is one of the simplest data structures. | | | The zero-based array was made popular by the C programming language, in which the abstraction of array is very weak, and an index n of an array is simply the address of the first element offset by n units. |

| | A dynamic array may be an element in a dimensioned array, in which case the dynamic array subscripts are specified following the dimensioned array subscript. | | | An array element is accessed by specifying its position in the array using a subscript variable. | | | The array is dimensioned based on the maximum attribute number addressed in the program, plus 1. |

| | Pointers II, Dynamic memory |
| | Memory allocation is all or nothing - if you allocate an array you must free the entire array - you cannot free memory piecewise. | | | The third major error that occurs with dynamic memory is freeing the same memory twice. | | | The second common mistake with dynamic memory is the ``dangling pointer'' (also called ``branch to fishkill'' or ``falling off the earth''). |

| | Vectors and Arrays - Language design and implementation |
| | For example, if a language has both dynamic arrays and bound checking, then the bounds (and strides) of arrays have to be decided at run-time, when the array is created, and passed on if the array is used as a parameter. | | | If the language allows slicing, then any array may be a slice from a higher-dimension array, so every array has to be treated as if it is dynamic - the origin, bounds and strides can only be calculated once the slice has happened, at run-time. | | | Most languages allow multi-dimensional arrays, either by having multiple indices or by permitting the element type to itself be an array, although some have a maximum allowed number of dimensions. |

| | The Old Joel on Software Forum - Dynamic Memory Management |
| | And "Managed memory" does not improve security except for that ONE particular exploit where you dynamically allocate an array on the stack, and the exploiter knows the exact size and parameters to overwrite it and stick a phony return address so it returns to a different location. | | | Dynamic memory management is a serious problem for server based applications, and I will not be easily convinced otherwise. | | | In a language like C++, you have to be sure to handle all out of memory exceptions, then be sure the handler for those exceptions doesn't need to allocate any dynamic memory. |

| | Week 8 - Dynamic Memory Allocation |
| | This is the memory address of the first element of the copy of the array. | | | Once all the computers memory is reserved the computer will probably crash. | | | Otherwise your programs may suffer something called memory leakage, in which the computer keeps reserving blocks of memory but never unreserves them so that the computers memory is slowly used up. |

| | If the block or procedure uses a dynamic array, for example, the space allocated to accommodate the new activation record will include space for exactly the correct number of array elements. | | | The example program above is somewhat contrived, in order to illustrate that despite the weirdness, under dynamic scoping (but not under static scoping) it will work. | | | dynamic scoping, if you call sum from within fblock, the effect is to execute sum in the environment of the calling block fblock, so that the situation now is as if sum is declared within fblock, so that f, also declared in fblock, is now visible to sum, so that sum can execute. |

| | Dynamic dispatch is implemented without any array access but uses a simple static binary branch code. | | | Obviously, this efficient technique can also be used for class-based languages without dynamic class creation: for example, it is possible for C++ or Java and not possible for Smalltalk. | | | Some more dispatch sites are removed after the type inference algorithm has been performed, if the different branches of a dispatch site lead to the same code. |

| | Chapter 3. Using Judy |
| | The Judy library functions support small or large, dynamic arrays with 32- or 64-bit indexes depending on the processor type. | | | A Judy array is created by storing (inserting) the first element and grows dynamically as elements are inserted. | | | While Judy is not primarily intended as a sorting algorithm, in many cases it's faster to store values in a Judy array and read them back in sorted order than to sort them using standard sorting algorithms. |

| | Dynamic Memory Allocation in Fortran |
| | This is much like a pointer in C, but we nevertheless tell Fortran that the object it is going to allocate dynamically is to be treated like an array and that a full set of array semantics must be applicable to it. | | | Instead we can allocate an appropriate amount of memory for the array dynamically, after having found how much is needed. | | | But allocatable arrays are supposed to be more efficient than pointers. |

| | Adding Multimethods to C++ |
| | In order to perform multimethod dispatch, one has to first decide which multimethod implementations match the dynamic types, and then try to find one of the multimethod implementations which can be considered a better match then all of the others. | | | This gives a dispatch speed of O(Log N), where N is the number of different combinations of dynamic types that have been encountered (some of which may be mapped to the same function pointer). | | | This allows a dispatch array of pointers to functions to be created for each multimethod, using the small integer identifiers as indices (in effect, this is making vtables that belong to individual multimethod dispatch functions rather than individual classes). |

| | Dynamic Memory Allocation, Part II |
| | Remember that an 80 char array embedded into a program takes 80 bytes of memory, but a pointer to a null value which will be allocated an 80 character array from dynamic memory takes only 4 bytes (pointers for 32-bit systems are 4 bytes). | | | This is why dynamic memory allocation is a good thing, so we can share the memory we have between all the programs that need it, and then return it when we are done. | | | Memory leaks are bad enough on Windows systems that have tons of memory, but on a little TI-89, it won't take long until all the memory is lost and a reset is the only way to fix the system. |
