Difference between Structure and Array in C Last Updated : 22 Dec, 2022 Comments Improve Suggest changes Like Article Like Report Array in C An array is collection of items stored at contiguous memory locations. Structure in C A structure is a user defined data type in C/C++. A structure creates a data type that can be used to group items of possibly different types into a single type. Difference between Structure and Array ARRAYSTRUCTUREArray refers to a collection consisting of elements of homogeneous data type.Structure refers to a collection consisting of elements of heterogeneous data type.Array uses subscripts or "[ ]" (square bracket) for element accessStructure uses "." (Dot operator) for element accessArray is pointer as it points to the first element of the collection.Structure is not a pointerInstantiation of Array objects is not possible.Instantiation of Structure objects is possible.Array size is fixed and is basically the number of elements multiplied by the size of an element.Structure size is not fixed as each element of Structure can be of different type and size.Bit field is not possible in an Array.Bit field is possible in an Structure.Array declaration is done simply using [] and not any keyword.Structure declaration is done with the help of "struct" keyword.Arrays is a non-primitive datatypeStructure is a user-defined datatype.Array traversal and searching is easy and fast.Structure traversal and searching is complex and slow.data_type array_name[size];struct sruct_name{ data_type1 ele1; data_type2 ele2; };Array elements are stored in contiguous memory locations.Structure elements may or may not be stored in a contiguous memory location.Array elements are accessed by their index number using subscripts.Structure elements are accessed by their names using dot operator.

The main difference lies in how they store data.The below table lists the primary differences between the C structures and unions:ParameterStructureUnionDefi 4 min read Difference between Array and Union in C 1. Array in C : An array is collection of similar data items accessed by a common name stored at continuous memory locations. The elements of an array can be accessed using indices. They can be used to store primitive data types such as int, float, double, char, etc. but all elements have to be of t 2 min read Difference between Arrays and Pointers The array and pointers are derived data types that have lots of differences and similarities. In some cases, we can even use pointers in place of an array, and arrays automatically get converted to pointers when passed to a function. So, it is necessary to know about the differences between arrays a 7 min read Difference Between C Structures and C++ Structures Let's discuss, what are the differences between structures in C and structures in C++? In C++, structures are similar to classes. Differences Between the C and C++ StructuresC Structures C++ Structures Only data members are allowed, it cannot have member functions.Can hold both: member functions and 6 min read Difference between Struct and Enum in C/C++ with Examples Structure in C++ A structure is a user-defined data type in C/C++. A structure creates a data type that can be used to group items of possibly different types into a single type. The ‘struct’ keyword is used to create a structure. Syntax: struct structureName{ member1; member2; member3; . . . member 3 min read Difference between pointer to an array and array of pointers Pointer to an array: Pointer to an array is also known as array pointer. We are using the pointer to access the components of the array. int a[3] = {3, 4, 5 }; int *ptr = a; We have a pointer ptr that focuses to the 0th component of the array. We can likewise declare a pointer that can point to whol 4 min read Relationship Between Pointer and Array in C In C programming language, pointers and arrays are closely related. An array name acts like a pointer constant. The value of this pointer constant is the address of the first element. If we assign this value to a non-constant pointer of the same type, then we can access the elements of the array usi 6 min read Difference Between one-dimensional and two-dimensional array Array is a data structure that is used to store variables that are of similar data types at contiguous locations. The main advantage of the array is random access and cache friendliness. There are mainly three types of the array: One Dimensional (1D) ArrayTwo Dimension (2D) ArrayMultidimensional Arr 3 min read What’s difference between “array†and “&array†for “int array[5]†? If someone has defined an array such as “int array[5]â€, what’s the meaning of “array†or “&arrayâ€? Are they both same or are they different? You might be tempted to think that they both would point to the very first element of the array i.e. they both will have same address. Let us find out!
