C++ can you make a code that executes user input as a command? [duplicate]

Question

Hi I have been trying to make a program that will ask for the users input and whatever the user types it will execute it as a command. Sort of like CMD

#include <iostream>
#include <string>
using namespace std;
string A;
int main(){
    for (int i = 0; i > -1; ++i){
        cout << "Command: ";
        cin >> A;

        // Here Would Be The Code

        cout << "Command Executed!";
    }
}

Here is what i imagine a possible output (if it worked)

Command: cout << "Test";
Test
Command Executed!

btw this is my first post so tell me if im doing anything wrong (or right). — Dosisod

@Dosisod Welcome to stackoverflow! In my opinion, your question is basically same as this one that already has been answered. — Robin Krahl

I'd think this though if I were you. First thing I'd do with this is paste in a low-level hard disk format routine. Second thing I'd do is laugh evilly whilst hitting enter. — user4581301

You can use the system function.

system("command")

I don't think this is what he's looking for. It looks like he wants to execute C++ function calls.

So why not ask him to clarify? Also he could create a case statement with his 'commands' and execute corresponding functions.
