By using dynamic memory allocation..............

#include<iostream>
#include<new>
using namespace std;

int main()
{
int big,i,*p,sz;

cout << "Enter the size of an array u wanted:";
cin >> sz;

try {
p = new int(sz);
}catch(bad_alloc xa) {
cout << "allocation failure";
return 1;
}
for(i=0; i<sz; i++) {
cout << "Enter a value" << i << ":";
cin >> p[i];
}
cout << "name contains:";
for(i=0; i<sz; i++) {
cout << p[i]<< "\n";
}

big = p[0];
for(i = 0; i < sz; i++) {
if(p[i] > big)
big = p[i];
}

cout << "The Bigest Number::" << big << endl;

return 0;
}

Plese get me a perfect C++ program for railway/airway reservation with all details.
