The main Difference Between Structure and Array In C Programming is “a structure is the collection of logically related data items which are grouped together under a single name, but an array is the collection of similar data types which can be represented by a single variable name”. We will discuss more the difference between structure and array in C Programming.

What is Structure in C Language?

A structure is a collection of logically related data items grouped together under a single name. In structure the individual elements may differ in type, that’s why we can regard structure as a heterogeneous user-defined data type. And the data items that are enclosed within a structure are known as members.

The Syntax for structure in C Language is:

  • struct struct_name
  • {
  •    data_type mem1;
  •    data_type mem2;
  •    …………………
  •    data_type memn;
  • };

The structure definition starts with keyword struct followed by an identifier which is a tag name. The tag name is structure name and can be used for instantiating structure variable. struct_name is referred to as structure name or structure tag name, and mem1, mem2, memn are known as structure members.

What is Array in C language?

An array is the collection of similar data types that can be represented by a single variable name. And the individual data items in an array are called elements. A data item is stored in memory in one or more adjacent storage location dependent upon its type.

The data types may be any valid data types like char, int or float. The element of array share the same variable name but each element has a different index of number known as a subscript. In c programming subscript starts from zero, here if age [10] is the variable name so the first element will be age [0] and second age [1] and so on.

An Array can be single dimensional or multidimensional the array of subscript determines the dimension of an array. One dimensional has one subscript and two dimensional has two subscript and so on.

Some of the types of Array are:

  1. One Dimensional Array
  2. Multi-Dimensional Array
  3. String

Top 10 Difference Between Structure and Array In C-Programming Language

There is ten difference between structure and array.

Structure :

  1. The Structure is defined as a collection of variables of different data types.
  2. The Structure elements might not be stored in the contiguous memory location.
  3. We can access structure elements by their names.
  4. Structure elements use “.” dot operator for accessing.
  5. The structure name is not a pointer because its name does not point to the first element in that structure.
  6. Structure objects can be created easily.
  7. Every element of the structure has different data types.
  8. The “struct” keyword is used to declare the structure.
  9. The structure in C language is not a user-defined datatype.
  10. It takes more time to access and search the structure elements.

Array :

  1. An array is defined as the collection of variables of the same data type.
  2. The array elements are stored in the contiguous memory location.
  3. We can access the array elements by their index number.
  4. Array elements use Square Brackets “[ ]” for access.
  5. The array name is a pointer because its name points to the first element in that array.
  6. Array objects cannot be created.
  7. Every element of an array is of the same size. 
  8. There is no such keyword to declare an array.
  9. The array in C programming is not user-defined but they are declared directly.
  10. It takes less time to access and search the array elements.
