#pragma warning (suppress: 4996)
#define _CRT_SECURE_NO_WARNINGS

#include
using namespace std;
#include
#include

int len ​​(struct PERSON p) {
    int leng = strlen (p.first);
    leng + = strlen (p.last);
    leng + = 4;
    return leng;
}

void fullName (char * p, struct PERSON & person) {
    char fullName [52];
    strcpy (person.first, fullName);
    strcat (fullName, "");
    strncat (fullName, person.middle, 1);
    strcat (fullName, "");
    strcat (fullName, person.last);
    p = fullName;
}

struct PERSON
{
    char first [25];
    char middle [25];
    char last [25];
    char * fullN;
};

int main () {
    struct PERSON * people;
    int num;
    cout << "enter num of persons" <
    cin >> num;
    while (num <0) {
        cout << "ERROR / n enter new num" << endl;
        cin >> num;
    }
    
    people = new PERSON [num];
    ifstream inData;
    inData.open ("data.txt");
    if (! inData.is_open ()) {
        cerr << "Cannot open input file \ n";
        exit (EXIT_FAILURE);
    }

    int i = 0;
    while (! inData.eof ()) {
        char str [100];
        inData >> people [i] .first;
        inData >> people [i] .middle;
        inData >> people [i] .last;
        people [i] .fullN = new char [len (people [i])];
    
        fullName (people [i] .fullN, people [i]);
        i + +;
    }
    inData.close ();
    0 return;
}
