Greeting Perl Gurus!

I am having a bit of a quandary, as I am a complete Perl newbie, and the answer to my question is probably an easy one. In short, I have a c++ app that calls a Perl script from the command prompt. When we call the script, we need to specify several variables, like name and IP address, which I need to be variables that can be passed in. How can I accomplish this? I would like to continue to use the command window as it is, just somehow add the variables in place of "name" and "IPAddress". If you could, please provide a code example of what it should look like. This is just a small part that will be added to a much larger application, and this is how the architect wants it done. Any help you can give me would be awesome!!!

Thanks!

My code follows...

#include<iostream>
#include<stdlib.h>
#include<stdio.h>
#include<string>
#include<fstream>


using namespace std;

int main()
{    
    string fName;
    string lName;
    string IPAddress;
    bool created;

    cout << "First Name: " << endl;
    cin >> fName;
    cout << "Last Name: " << endl;
    cin >> lName;

    
    system("cmd.exe /C \"c:\\Program Files\\Forterra\\OLIVE SDK 2.0.1\
+\util\\legacy\\src\\Tool\\AddAvatar.pl\" --name=Bacon N Eggs --host=1
+27.0.0.1:9911"); //
    created = true;
    
    if (created == true)
    {
        cout << "Your Avatar's name is: " << fName  << " " << lName <<
+ endl;
        ofstream aviFile("aviList.txt", ios::app);
        aviFile << fName << " " << lName << endl; 
        aviFile.close();
        
    }
    else
    {
        cout <<"Your avatar was not able to be created or already exis
+ts. Contact your system administrator"<< endl;
    }
    system("pause");
    return 0; 
}
