splitting inputs....im so dumb =)

char one[5],two[5];

gets(one);
strcpy(two,&one[5]);
one[5] = 0;

#include <iostream>
using namespace std;

int main()
{
	int my8digitnumber;
	int first4digits, last4digits;
	cout << "Enter an eight-digit number: ";
	cin >> my8digitnumber;
	first4digits = my8digitnumber / 10000; //since first4digits is an integer variable, the decimal portion will be stripped off
	last4digits = my8digitnumber % 10000; // the % operator, called modulus, performs division returns the remainder
	cout << "First 4 digits: " << first4digits << ". Last 4 digits: " << last4digits << "." << endl;
	
	cin.ignore();
	cin.get();
	return 0;
}
