Syntax

Consider a vector 'v' and capacity 'c'. Syntax would be :

Parameter

It does not contain any parameter.

Return value

It returns the current allocated capacity of the vector.

Example 1

Let's see a simple example.

Output:

Capacity of the vector is :5

In this example, vector v containing integer values and capacity() function finds the capacity of the vector v.

Example 2

Let's see a another simple example.

Output:

Capacity of the vector is :5
