Output from function in another one

In my C++ project, I have 3 files which are main.cpp, functions.cpp and functions.h.

functions.cpp:

#include <functions.h>

using namespace std;

int ascii(string text)
{
    vector<int> tab;

    for( int i=0; i<text.length(); i++ )
    {
        char x = text.at(i);
        tab.push_back(x);
    }

    for(int k=0; k<tab.size(); k++)
    {
        cout << tab[k] << endl;
    }
}

functions.h:

#ifndef FUNCTIONS_H_INCLUDED
#define FUNCTIONS_H_INCLUDED

#include <iostream>
#include <string>
#include <vector>

int ascii(std::string text);

#endif // FUNCTIONS_H_INCLUDED

main.cpp:

#include <functions.h>

using namespace std;

int main()
{
    string plaintext;
    cout << "Enter text : ";
    ws(cin);
    getline(cin, plaintext);

    ascii(plaintext);

    return 0;
}

As you can see, the value are stored in an array in the functions.cpp file.

How do I "move" the array from functions.cpp to main.cpp so I can manipulate these data?

One way is to do following

functions.cpp

using namespace std;

vector<int> ascii(string text) // original: int ascii(string text)
{
    vector<int> tab;

    for( int i=0; i<text.length(); i++ )
    {
        char x = text.at(i);
        tab.push_back(x);
    }

    for(int k=0; k<tab.size(); k++)
    {
        cout << tab[k] << endl;
    }

    return tab;  // original: no return
}

functions.h

#ifndef FUNCTIONS_H_INCLUDED
#define FUNCTIONS_H_INCLUDED

#include <iostream>
#include <string>
#include <vector>

std::vector<int> ascii(std::string text); // original int ascii(std::string text)

#endif // FUNCTIONS_H_INCLUDED

main.cpp

#include <functions.h>

using namespace std;

int main()
{
    string plaintext;
    cout << "Enter text : ";
    ws(cin);
    getline(cin, plaintext);

    vector<int> returning = ascii(plaintext); // original: ascii(plaintext)

    return 0;
}
