It looks like you really need to review your documentation on how to do basic file input and output. Perhaps start here:
http://www.cplusplus.com/doc/tutorial/files/

Next, after you review your documentation you should realize that your variable file will never be equal to ";".

I'm not sure that a single array of strings is the best choice. You might use a 2D array, but maybe a vector of 'person' objects might be better.

#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <sstream>
#include <vector>

struct Person {
    int id;
    std::string name;
    int num;
};

using namespace std;

int main()
{
    ifstream fin("persons.csv");
    if (!fin)
    {
        cout << "File not open\n";
        return 1;
    }
    
    vector<Person> persons;
    
    string line;
    const char delim = ';';
    
    while (getline(fin, line))
    {
        istringstream ss(line);
        Person person;
        ss >> person.id; ss.ignore(10, delim); 
        getline(ss, person.name,delim);
        ss >> person.num;
        if (ss)
            persons.push_back(person);
    }
    
    
    for (unsigned int i=0; i< persons.size(); i++)
        cout << setw(5)  << persons[i].id 
             << setw(25) << persons[i].name
             << setw(8)  << persons[i].num 
             << '\n';
}

Output

    1                    Peter     230
    5                  Merrick     255
    6                    Lucky     430
