C++ Vector rbegin
The rbegin method stands for 'reverse begin' and is employed to reference the final element of the vector.
Syntax
Consider a vector 'v' and syntax would be :
Example
reverse_iterator ritr=v.rbegin();
Parameter
It does not contain any parameter.
Return value
It provides a reverse iterator that points to the final element within the vector.
Example
Let's see a simple example.
Example
#include <iostream>
#include<vector>
using namespace std;
int main()
{
vector<char> v{'j','a','v','a'};
vector<char>::reverse_iterator rtr;
for(rtr=v.rbegin();rtr!=v.rend();rtr++)
std::cout<< *rtr;
return 0;
}
Output:
In this instance, the rbegin method is employed to retrieve the reversed string stored within the vector.
