std::vector::erase

iterator erase( iterator pos );	(until C++11)
iterator erase( const_iterator pos );	(since C++11)
	(2)
iterator erase( iterator first, iterator last );		(until C++11)
iterator erase( const_iterator first, const_iterator last );		(since C++11)

Removes specified elements from the container.

1) Removes the element at pos.

2) Removes the elements in the range [first; last).

Example

#include <vector>
#include <iostream>
 
 
int main( )
{
    std::vector<int> c{0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
    for (auto &i : c) {
        std::cout << i << " ";
    }
    std::cout << '\n';
 
    c.erase(c.begin());
 
    for (auto &i : c) {
        std::cout << i << " ";
    }
    std::cout << '\n';
 
    c.erase(c.begin()+2, c.begin()+5);
 
    for (auto &i : c) {
        std::cout << i << " ";
    }
    std::cout << '\n';
}

output
