Arrays are collections of repeated data items. Structures are complex data items made up of other data items, including, potentially, other structures and arrays. You can, of course, also have arrays of structures.
Array items can be accessed by using its subscript whereas structure items can be accessed using its dot or "arrow" operator in C, C++, C#, Java, and JavaScript.
What else can I help you with?
Which data structures are indexed?
Arrays.
What are the differences between arrays and records in computer programming?
Records are distinguished from arrays by the fact that their number of fields is typically fixed, each field has a name, and that each field may have a different type.
What is the linear data structures?
Linear data structures are 1-dimensional arrays, as in: vectors.
How do you find the difference between two arrays in Java?
for arrays you can list the different arrays and what attributes that you give to them.
What are the differences between natural and man-made structures?
Natural structures are formed by themselves whereas man made structures are built to look like something ...
What are the differences between natural and man made structures?
man made structures are something that a human builds, and a natural structure is something that comes into the world naturally.
What do you meant by array of structures?
The elements of the arrays are structures. Example: struct { int x, y, z; } cube [8]; cube[0].x = 1;
Is String a linear data structure?
yes it is, other linear data structures are lists,queues,stacks,arrays
What are the differences between adjacency matrix and adjacency list in terms of representing graph data structures?
An adjacency matrix represents a graph as a 2D array where each cell indicates if there is an edge between two vertices. It is good for dense graphs but uses more memory. An adjacency list uses a list of linked lists or arrays to store edges for each vertex. It is better for sparse graphs and uses less memory.
What are the properties of a contiguous array and how can it be efficiently utilized in data structures and algorithms?
A contiguous array is a data structure where elements are stored in adjacent memory locations. This allows for efficient access to elements using indexing. Contiguous arrays are commonly used in data structures like arrays and lists, as they enable fast retrieval and manipulation of elements. In algorithms, contiguous arrays can be utilized to optimize operations such as searching, sorting, and iterating through elements. This efficient utilization of contiguous arrays helps improve the performance and speed of algorithms.
Why can we use foreach loop for arrays although arrays do not implement Iterable?
In PHP, the foreach loop can be used with arrays because it is specifically designed to work with array data structures, even though arrays do not implement the Iterable interface. The foreach construct is able to iterate over arrays directly, utilizing the internal array handling mechanisms of the language. This allows for a more straightforward syntax for looping through elements without the need for additional constructs. Thus, foreach provides a convenient and efficient way to process arrays in PHP.
What are the differences between an adjacency matrix and an adjacency list in terms of representing graph data structures?
An adjacency matrix is a 2D array that represents connections between nodes in a graph, with each cell indicating if there is an edge between two nodes. An adjacency list is a collection of linked lists or arrays that stores the neighbors of each node. The main difference is that an adjacency matrix is more space-efficient for dense graphs, while an adjacency list is more efficient for sparse graphs.
