为例

#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:

0 1 2 3 4 5 6 7 8 9
1 2 3 4 5 6 7 8 9
1 2 6 7 8 9

复杂性

1) linear in the distance between position and last.

2) linear in distance between position and the end of the container.
