program for getting and setting tasks

[dpdanpittman]

so i've completely re-written this program. entering tasks works and searching for tasks also works. When displaying all of the tasks in the file however the program loops infinitely. Im not sure why it does I'm pretty sure i did the algorithm right but I have also been staring at it forever so need a new pair of eyes. so heres the code

//this is the header file for labThree

#ifndef ADD_H
#define ADD_H

//class TaskList does different operations on the task list
class TaskList
{

public:	
	void userInterface(); //displays all of the choices
	void makeChoice();
	void enterTasks(); //asks user to enter task name, description and due date
	void searchForTaskName(); //searches "task.txt" for specific tasks
	void displayAllTasks(); //displays all of the tasks in "task.txt"
	
};

//class Task sets and gets the different tasks
class Task
{

public:
	//accessors
	void getTaskName();  //gets the name of the task from the user
	void getDescription(); //gets the description
	void getDueDate(); //gets the due date

	//mutators
	void setTaskName(); //outputs the task name to "tasks.txt"
	void setDescription(); //outputs the description to "task.txt"
	void setDueDate(); //outputs the due date to "task.txt"

	char taskName[100];
	char taskDescription[5000];
	char taskDueDate[10];
};

#endif 

//this is the implementation file for labThree

#include "tasks.h"

#include <string>

using namespace std;

//creating the user interface
void TaskList::userInterface()
{
	//prints user interface to the screen using cout
	cout	<< "Welcome to your task organizer!\n\n"
