Skip a line of code?? How??

Could someone please help me...

I wrote some code for an assignment. Everything works great except for this one line of code. (Below with note)

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

int main()
{
string name, address, city, state;
int zip;

cout << "Please enter sender's information.";
cout << "\n\nFirst and last name: ";
getline( cin, name );
cout << "Street address: ";
getline( cin, address );
cout << "City: ";
getline( cin, city );
cout << "State: ";
getline( cin, state );
cout << "Zip Code: ";
cin >> zip;

cout << endl << endl;

cout << name << endl << address << endl << city << ", " << state << " " << zip;

cout << endl << endl;

cout << "Please enter receiver's information.";
cout << "\n\nFirst and last name: "; // :confused: This is where I'm having issues
getline( cin, name ); // <-- :confused: Why does it skip this line of code?
cout << "Street address: ";
getline( cin, address );
cout << "City: ";
getline( cin, city );
cout << "State: ";
getline( cin, state );
cout << "Zip Code: ";
cin >> zip;

cout << endl << endl;

cout << name << endl << address << endl << city << ", " << state << " " << zip;

cout << endl << endl;

system("PAUSE");
system("cls");
}

Let me know if anyone needs me to explain.

Does it work in the first place? You didnt declare and initialize the strings, instead you had the user input the information twice.

is this from the introduction to computer science using C++ book?

Probably <Enter> key, pressed for previous "cin >> zip" operation, affects the getline operation. I think you should replace all of getline operations with ">>", for example:
cin >> name;
I hope this helps.
