问如何在c++中使用delete操作符删除单个数据

EN

auto x = new int[10];  // An array of ten things.
delete[] x;            // Delete the *entire* array.

delete &(x[7]);        // Try to delete the eight item.

#include <iostream>
#include <vector>

int main() {
    // Create a vector: 11, 22, ... 99.

    std::vector<int> vec;
    for (auto i = 11; i <= 99; i += 11)
        vec.push_back(i);

    // Remove the fifth thru sixth, and third elements (55, 66, 33).

    vec.erase(vec.begin() + 4, vec.begin() + 6);
    vec.erase(vec.begin() + 2);

    // Output modified vector.

    for (auto val: vec)
        std::cout << val << ' ';
    std::cout << '\n';
}
