将上述代码转化为c++

以下是将上述bash代码转换为C ++的示例：

1. pmap -x

#include <iostream>
#include <fstream>
#include <sstream>
#include <string>
#include <vector>

using namespace std;

int main(int argc, char* argv[]) {

    if (argc != 2) {
        cout << "Usage: pmap -x <PID>" << endl;
        return 1;
    }

    int pid = atoi(argv[1]);

    stringstream ss;
    ss << "/proc/" << pid << "/maps";
    string maps_file = ss.str();

    ifstream ifs(maps_file.c_str());
    if (!ifs.good()) {
        cout << "PID " << pid << " not found." << endl;
        return 1;
    }

    cout << "Address           Kbytes     RSS   Dirty Mode    Mapping" << endl;

    string line;
    while (getline(ifs, line)) {
        if (line.find("rw-p") != string::npos) {
            istringstream iss(line);
            string addr, perms, offset, dev, inode, pathname;
            int kbytes, rss, dirty;
            iss >> addr >> perms >> kbytes >> rss >> dirty >> offset >> dev >> inode >> pathname;
            cout << left << setw(17) << addr << setw(10) << kbytes << setw(8) << rss << setw(7) << dirty
                << setw(9) << perms << " " << pathname << endl;
        }
    }

    return 0;
}

2. pmap -X

#include <iostream>
#include <fstream>
#include <sstream>
#include <string>
#include <vector>

using namespace std;

int main(int argc, char* argv[]) {

    if (argc != 2) {
        cout << "Usage: pmap -X <PID>" << endl;
        return 1;
    }

    int pid = atoi(argv[1]);

    stringstream ss;
    ss << "/proc/" << pid << "/maps";
    string maps_file = ss.str();

    ifstream ifs(maps_file.c_str());
    if (!ifs.good()) {
        cout << "PID " << pid << " not found." << endl;
        return 1;
    }

    cout << "Address           Kbytes     RSS   Dirty Mode    Mapping" << endl;

    string line;
    while (getline(ifs, line)) {
        if (line.find("rw-p") != string::npos) {
            istringstream iss(line);
            string addr, perms, offset, dev, inode, pathname;
            int kbytes, rss, dirty;
            iss >> addr >> perms >> kbytes >> rss >> dirty >> offset >> dev >> inode >> pathname;
            cout << left << setw(17) << addr << setw(10) << kbytes << setw(8) << rss << setw(7) << dirty
                << setw(9) << perms << " " << pathname << endl;

            stringstream ss2;
            ss2 << "/proc/" << pid << "/smaps";
            string smaps_file = ss2.str();

            ifstream ifs2(smaps_file.c_str());
            if (!ifs2.good()) {
                cout << "Unable to open " << smaps_file << endl;
                continue;
            }

            string line2;
            bool found = false;
            while (getline(ifs2, line2)) {
                if (line2.size() > 11 && line2.substr(0, 11) == "Address: " + addr) {
                    cout << "    " << line2 << endl;
                    found = true;
                }
                else if (found) {
                    break;
                }
            }
        }
    }

    return 0;
}

这些示例使用了C ++标准库中的文件读取和字符串处理函数。请注意，这些示例的输出格式可能与原始bash示例不完全相同。
