something like this:

while(true)
{
    std::string command;
    std::cout << "enter a command: ";
    std::cin >> command;

    if(command == "hello")
        system(".\hello.exe"); // name of the programm you want to start
    if(command == "quit")
        break;
}

so what you're trying to do is you want to create a command line, kinda like terminal or Cmd.
put all the code in a while loop.(the condition should always be true, else the command wont work).
the code inside the loop should look like this:

string mycommand;
cout << "Enter A Command:";
cin >> mycommand;                  //here you type your command,for example the "hello" command
if(mycommand == "hello") {        //or any other command
system(".\hello.exe")                  //destination of the program you want to start
}

would it have to be a /exe? or could it be another c++ file?

How do you run a c++ file?

do you mean open the IDE and that file in it?
