以下是将给定的 Python 代码转换为 C++ 代码的过程：

#include<iostream>
#include<vector>
#include<algorithm>
using namespace std;

int calculate_w(int a, int b, vector<int>& list_) {
    if (list_[0] <= 0) {
        if (list_[2] < a) {
            return list_[2];
        }
        else {
            return a;
        }
    }
    else {
        if (list_[2] < a) {
            return list_[2] - list_[0];
        }
        else {
            return a - list_[0];
        }
    }
}

int calculate_l(int a, int b, vector<int>& list_) {
    if (list_[1] <= 0) {
        if (list_[3] < b) {
            return list_[3];
        }
        else {
            return b;
        }
    }
    else {
        if (list_[3] < b) {
            return list_[3] - list_[1];
        }
        else {
            return b - list_[1];
        }
    }
}

int calculate(int a, int b, vector<int>& list_) {
    return calculate_w(a, b, list_) * calculate_l(a, b, list_);
}

int judge(int a, int b, vector<int>& list_) {
    if (list_[0] > 0 && list_[1] > 0 && list_[2] < a && list_[3] < b) {
        return ((list_[2] - list_[0]) * (list_[3] - list_[1]));
    }
    else if (list_[0] >= a || list_[1] >= b || list_[2] <= 0 || list_[3] <= 0) {
        return 0;
    }
    else {
        return calculate(a, b, list_);
    }
}

int calculate_sum(int n, int a, int b, int sum, vector<vector<int>>& list_num) {
    for (int i = 0; i < n; i++) {
        sum = sum + judge(a, b, list_num[i]);
    }
    return sum;
}

int main() {
    int n, a, b, sum = 0;
    cin >> n >> a >> b;
    vector<vector<int>> list_num(n, vector<int>(4));
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < 4; j++) {
            cin >> list_num[i][j];
        }
    }
    cout << calculate_sum(n, a, b, sum, list_num);
    return 0;
}

注意，C++ 中需要使用向量（vector）来存储二维数组。同时，C++ 中的数组下标是从 0 开始的，而 Python 中是从 1 开始的。因此在 C++ 中需要将数组下标都减去 1。
