Person/Name Database

I have tried to create a program where the user inputs a name and then it calls upon a function to report data about that person's name. I just wasn't sure how to properly call upon just 1 person's name instead of all of them. I only have 2 examples so far. These names are fake and maid up by the way. This program is just for fun and for learning. Sorry if I posted in the wrong forum or anything like that, this is my first post :)

So far my code is:

#include <cstdlib>
#include <iostream>
#include <cmath>
#include <string>

void Liz_Jacobin(int);

void Jake_Jones(int);

using namespace std;

int main()
{
string name;
int a;
int call;
int password;
system("color 0A");

cin >> name;
cout << "The person you have requested info about is ";
cout << "[";
cout << name;
cout << "]";
cout << endl;
cout << "Enter you administer password ";
cin >> password;
cout << endl;
cout << endl;
cout << "Your data includes";
cout << endl;
name = a;
if (a == Liz_Jacobin)
Liz_Jacobin(call);

if (a == Jake_Jones)
Jake_Jones(call);

cout << endl;

system("pause");
return 0;
}

void Liz_Jacobin(int x)
{
string data;
using namespace std;
data = "Liz is a girl ";
cout << data;
cout << endl;
}

void Jake_Jones(int x)
{
string data;
using namespace std;
data = "Jake plays soccer ";
cout << data;
cout << endl;
}
