Difference between Array and Structure

Main Difference

The two terms getting discussed in this article are array and structure, and they have several differences that a reasonable person cannot detect on their own. They have their meaning and working, and that makes for an interesting read. The main difference between all such types gets explained in the following ways. In computer, programming array gets defined as the set of an element or the entity which keeps the element of the same kind in one place. On the other hand, In computer programming structure gets defined as the data structure which keeps the elements of different kinds in one place. Although the primary task of it becomes to maintain the information stored.

Comparison Chart

Basis of Distinction Array Structure
Definition The set of an element or the entity which keeps the element of the same kind in one place. The data structure which keeps the elements of different kinds in one place.
Representation “array arrayName [ arraySize ];”. “struct [structure tag].
Values Only takes either integer or alphabetical values at one time of operation. Takes both the integer or alphabetical values or others during one operation.
Space The space allocated for memory is always static. The space allocated by a structure for memory is always dynamic.
Access Uses “/” to access elements within the program. Uses (.) to access elements within the program.

Array

In computer programming array gets defined as the set of an element or the entity which keeps the element of the same kind in one place. Although the primary task of it remains the storing of information that comes from the variables but the better thing to do is to consider it as a collection of variables that have the same type. C++ gives an information structure, the cluster, which stores a settled size consecutive gathering of components of a similar sort. An exhibit is utilized to store a collection of information. However, it is regularly more valuable to think about a cluster as an accumulation of factors of a similar sort. Rather than proclaiming singular elements, for example, number0, number1, …, and number99, you pronounce one cluster variable, for example, numbers and utilize numbers[0], numbers[1], and …, numbers[99] to speak to individual factors. A particular component of an exhibit by a file. To pronounce a cluster in C++, the developer indicates the sort of the components and the number of elements required by an exhibit as takes after: “type arrayName [ arraySize ];” This gets known as a solitary measurement show. The arraySize must be a number steady more prominent than zero and sort can be any legitimate C++ information type. For instance, to pronounce a 10-component exhibit called adjust of sort twofold. C/C++ displays enable you to characterize factors that join a few information things of a similar kind yet the structure is another client described data type which allows you to consolidate information things of various types.

Structure

In computer programming structure gets defined as the data structure which keeps the elements of different kinds in one place. Although the primary task of it becomes to maintain the information stored, but it does so with any variable and data type, be it integer or alphabet and therefore has wide-ranging benefits. Structures are utilized to speak to a record, assume you need to monitor your books in a library. You might need to track the accompanying qualities about each book, for example, its Title, Author, Subject, Book ID. For instance: You need to store some data about a man: his/her name, citizenship number and pay. You can without much of a stretch make distinguishing factors name, citNo, compensation to store these data independently. In any case, later on, you would need to store data about different people. Presently, you’d have to make different factors for every data per individual: name1, citNo1, salary1, name2, citNo2, salary2. The structure tag is discretionary, and every part definition is a common variable definition, for example, int i; or buoy f; or whatever other substantial variable definition. Toward the finish of the structure’s definition, before the last semicolon, you can indicate at least one structure factors, yet it is discretionary. To characterize a structure, you should utilize the struct explanation. The struct proclamation describes another information sort, with more than one part, for your program. The organization of the struct articulation is this: “struct [structure tag].

Key Differences

  • In computer programming array gets defined as the set of an element or the entity which keeps the element of the same kind in one place. On the other hand, In computer programming structure gets defined as the data structure which keeps the elements of different kinds in one place.
  • The way of representing a structure becomes;  “struct [structure tag]. On the other hand, the way of representing an array becomes; “array arrayName [ arraySize ];”.
  • An array only takes either integer or alphabetical values at one time of operation, on the other hand, a structure takes both the integer or alphabetical values or others during one operation.
  • The best example of an array is the number of students in one class, we can take the student 1, student 2, student 3 and more in the same array. On the other hand, the best example of the structure becomes the name and the age of the student, as age 1, age 2, age 3, and name 1, name 2 and name 3.
  • The space allocated for an array for memory is always static, on the other hand, the space allocated by a structure for memory is always dynamic.
  • An array uses “/” to access elements within the program, on the other hand, a structure always uses (.) to access elements within the program.
