用c++写一个银行家算法代码，有资源的释放功能，另外要求解释输出部分用中文

以下是一个带资源释放功能的银行家算法 C++ 代码，另外将解释输出部分改为中文：

#include<iostream> 
#include<vector>

using namespace std; 

int main() 
{ 
    int n, m; 

    cout << "请输入进程数: "; 
    cin >> n; 

    cout << "请输入资源数: "; 
    cin >> m; 

    int allocated[n][m], maximum[n][m], available[m]; 

    cout << "请输入每个进程已分配的资源数:\n"; 
    for(int i = 0; i < n; i++) 
        for(int j = 0; j < m; j++) 
            cin >> allocated[i][j]; 

    cout << "请输入每个进程最大需求的资源数:\n"; 
    for(int i = 0; i < n; i++) 
        for(int j = 0; j < m; j++) 
            cin >> maximum[i][j]; 

    cout << "请输入可用的资源数: \n"; 
    for(int i = 0; i < m; i++) 
        cin >> available[i]; 

    int need[n][m]; 
    for(int i = 0; i < n; i++) 
        for(int j = 0; j < m; j++) 
            need[i][j] = maximum[i][j] - allocated[i][j]; 

    bool finish[n] = {0}; 
    int safe_sequence[n], work[m]; 
    for(int i = 0; i < m; i++) 
        work[i] = available[i]; 

    int count = 0; 
    while(count < n) 
    { 
        bool found = false; 
        for(int i = 0; i < n; i++) 
        { 
            if(finish[i] == 0) 
            { 
                int j; 
                for(j = 0; j < m; j++) 
                    if(need[i][j] > work[j]) 
                        break; 

                if(j == m) 
                { 
                    for(int k = 0; k < m; k++) 
                        work[k] += allocated[i][k]; 

                    safe_sequence[count++] = i; 
                    finish[i] = 1; 
                    found = true; 
                } 
            } 
        } 

        if(found == false) 
        { 
            cout << "系统不处于安全状态。"; 
            return 0; 
        } 
    } 

    cout << "安全序列为: "; 
    for(int i = 0; i < n; i++) 
        cout << safe_sequence[i] << " "; 

    // 释放资源 
    vector<int> release_sequence;
    bool released[n] = {0};
    char ch;
    do {
        int pid;
        cout << "\n请输入要释放资源的进程 ID: ";
        cin >> pid;

        while (pid < 0 || pid >= n || released[pid]) {
            cout << "进程 ID 无效或该进程已释放，请重新输入: ";
            cin >> pid;
        }

        for (int i = 0; i < m; i++) {
            int r;
            cout << "请输入要释放的资源 R" << i << " 数量: ";
            cin >> r;
            while (r < 0 || r > allocated[pid][i]) {
                cout << "要释放的资源数量无效，请重新输入: ";
                cin >> r;
            }
            allocated[pid][i] -= r;
            need[pid][i] += r;
            available[i] += r;
        }

        released[pid] = true;
        release_sequence.push_back(pid);

        cout << "是否继续释放资源？(y/n) ";
        cin >> ch;
    } while (ch == 'y' || ch == 'Y');

    // 再次运行银行家算法，检查释放资源后系统是否处于安全状态
    int new_safe_sequence[n], new_count = 0; 
    bool new_finish[n] = {0}; 
    int new_work[m]; 
    for(int i = 0; i < m; i++) 
        new_work[i] = available[i];

    while(new_count < n) 
    { 
        bool new_found = false; 
        for(int i = 0; i < n; i++) 
        { 
            if(new_finish[i] == 0) 
            { 
                int j; 
                for(j = 0; j < m; j++) 
                    if(need[i][j] > new_work[j]) 
                        break; 

                if(j == m) 
                { 
                    for(int k = 0; k < m; k++) 
                        new_work[k] += allocated[i][k]; 

                    new_safe_sequence[new_count++] = i; 
                    new_finish[i] = 1; 
                    new_found = true; 
                } 
            } 
        } 

        if(new_found == false) 
        { 
            cout << "\n释放资源后，系统不处于安全状态。"; 
            return 0; 
        } 
    } 

    cout << "\n释放资源后，系统处于安全状态。新的安全序列为: "; 
    for(int i = 0; i < n; i++) 
        cout << new_safe_sequence[i] << " "; 

    cout << "\n释放资源的顺序为: "; 
    for (int i = 0; i < release_sequence.size(); i++) 
        cout << release_sequence[i] << " "; 

    return 0; 
} 

在这个版本的代码中，我们添加了一个循环，允许用户输入要释放资源的进程 ID 和要释放的资源数量，并将已释放的进程标记为已释放。在用户选择不再释放资源后，代码会再次运行银行家算法，以检查释放资源后系统是否处于安全状态。如果系统不再安全状态，代码将输出一条消息，并退出程序。如果系统处于安全状态，代码将输出新的安全序列和释放资源的顺序。
