#include <iostream>
#include <string>

using namespace std;
struct data {
       int nr;
       string fname;
       string lname;
       };
void create(data& a, int n) {
     int i;
     for (i=0;i<n;i++) {
         cout <<"Number: ";
         cin >>a[i].nr;
         cout<<endl;
         cin.ignore();
         cout <<"First Name: ";
         getline(cin,a[i].fname);
         cout <<"Last Name: ";
         getline(cin,a[i].lname);
         }
     }
void show(data a, int n) {
     int i;
     for (i=0;i<n;i++) {
         cout <<"\nNumber: "<<a[i].nr<<endl;
         cout <<"First Name: "<<a[i].fname<<endl;
         cout <<"Last name: "<<a[i].lname<<endl;
         cout <<"_______________________________"<<endl;
         }
     }
int main () {
    int n,i;
    cout <<"Number of persons in family: ";
    cin >>n;
    data *a=new (nothrow) data[n];
    if (a==0) cout <<"Error, please try again";
    else {
         create(a,n);
         show(a,n);
         }
         delete [] a;
    system("pause");
    return 0;
    }



it says "In function `void create(data&, int)
no match found for operator[] in a'[i]'
and other errors :(
Please help!
Seeing as you are passing a pointer to an array of class objects to the create/show functions that is what they need to accept as their parameters.

Changing the functions to (data* a, int n) { should solve the problem.
damn it worked, THANKS MAN!
its always the small mistakes that ruin a big program :P
