C++ Problem Help

Hi I need help fixing my program. The last void function is where the issue occurs. I want it to allow the user to enter the city name and then output the corresponding zip code. It allows me to enter a city name but then does not show anything else. Can someone tell me what my error is?

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

//function prototypes
int displayMenu();
void displayInfo();
void addInfo();
void displayCity();
void displayZip();

int main()
{
int menuChoice = 0;

//display menu and get choice
menuChoice = displayMenu();

//call appropriate function or display error
while (menuChoice != 5)
{
if(menuChoice == 1)
addInfo();
else if(menuChoice == 2)
displayInfo();
else if(menuChoice == 3)
displayCity();
else if(menuChoice == 4)
displayZip();
else
cout << "Invalid choice" << endl;
//end ifs

//display menu and get choice
menuChoice = displayMenu();
}//end while

system("pause");
return 0;
} //end of main function

// Function definitions

int displayMenu()
{
//display a menu and then gets and returns users choice
int choice = 0;
cout << endl;
cout << "1. Add Information" << endl;
cout << "2. Display Information" << endl;
cout << "3. Display City" << endl;
cout << "4. Display Zip Code" << endl;
cout << "5. Exit Program" << endl;
cout << "Enter your choice: ";
cin >> choice;
cout << endl;
cin.ignore(100, '\n');
return choice;
}//end of displayMenu function

void displayInfo()
{
//displays the records stored in the zip.txt file

}
else

}//end of addInfo function

{
//reads records from a file and displays the City to the corresponding zip code entered by the user

int zip = 0;
int code = 0;

//create file object and open the file
ifstream inFile;

It's so hard to read, I suggest using code tags.
