C++ Vector rbegin
The rbegin stands for 'reverse beginning' and is used to point the last 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 returns a reverse iterator pointing to the last element of 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 example, rbegin function is used to get the reverse string contained in the vector.
