    #include <iostream>    #include <stdio.h>    #include <stdlib.h>    using namespace std;    string cmdinput;    string GetStdoutFromCommand(string cmd) {    string data;    FILE * stream;    const int max_buffer = 256;    char buffer[max_buffer];    cmd.append(" 2>&1");    stream = popen(cmd.c_str(), "r");    if (stream) {    while (!feof(stream))    if (fgets(buffer, max_buffer, stream) != NULL) data.append(buffer);    pclose(stream);    }    return data;    }    int main (){        cout << "Enter your command:" << endl;        string cmdinput;        getline (cin, cmdinput);        cout << "Your command was ‘" << cmdinput << "‘" << endl;      string com = GetStdoutFromCommand(cmdinput);      cout << "Command: " << com << endl;    return 0;    }

in this way you can easy get the output string of your input command in C++
