Array vs. Vector (Advantages and Disadvantages)

Array vs. Vector

• A vector is a dynamic array, whose size can be increased, where as an array size can not be changed.
• Reserve space can be given for vector, where as for arrays can not.
• A vector is a class where as an array is not.
• Vectors can store any type of objects (without generics) , where as an array can store only homogeneous values.

Advantages and Disadvantages

Advantages of Arrays

• Arrays supports efficient random access to the members.
• It is easy to sort an array.
• They are more appropriate for storing fixed number of elements

Disadvantages of Arrays

• Elements can not be deleted
• Dynamic creation of arrays is not possible
• Multiple data types cannot be stored

Advantages of Vector

• Size of the vector can be changed
• Multiple objects can be stored
• Elements can be deleted from a vector

Disadvantages of Vector

• A vector is an object , memory consumption is more.
