Advantages of Vector Over Array in C++

Vector is a template class and is C++ only construct whereas arrays are built-in language construct and present in both C and C++.

Vector are implemented as dynamic arrays with list interface whereas arrays can be implemented as statically or dynamically with primitive data type interface.

Differences between a Vector and an Array

• A vector is a dynamic array, whose size can be increased, whereas THE array size can not be changed.

• Reserve space can be given for vector, whereas for arrays you cannot give reserved space.

• A vector is a class whereas an array is a datatype.

• Vectors can store any type of objects, whereas an array can store only homogeneous values.

Advantages of Arrays

• Arrays support efficient random access to the members.

• It is easy to sort an array.

• They are more appropriate for storing a fixed number of elements

Disadvantages of Arrays

• Elements can not be deleted

• Dynamic creation of arrays is not possible

• Multiple data types can not 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.
