std :: vector中的内存泄漏代表2D数据

#include <iostream>
#include <vector>

int main() {
    std::vector<int*> vec;
    for (int i = 0; i < 10; i++) {
        vec.push_back(new int(i));
    }

    // 释放内存
    for (int* p : vec) {
        delete p;
    }

    return 0;
}

#include <iostream>
#include <vector>

int main() {
    std::vector<int*> vec;
    vec.push_back(new int(1));
    vec.push_back(new int(2));
    vec.push_back(new int(3));

    // 释放内存
    for (int* p : vec) {
        delete p;
    }

    return 0;
}
