C++ Vector rend()

The rend() function stands for 'reverse end' and is used to point the element preceding the first element of the vector.

Syntax

Consider a vector 'v'. Syntax would be:

Parameter

It does not contain any parameter.

Return value

It returns a reverse iterator pointing to the reverse end of the vector container.

Example 1

Let's see a simple example.

Output:

5 4 3 2 1

In this example, rend() function is used to get reverse integer values contained in the vector.

Example 2

Let's see a simple example.

Output:

Strings are :Computer science, electronics, mechanical
Reverse strings are :mechanical, electrical, electronics, Computer science

In this example, rend() function is used to get reverse string values contained in the vector.
