I'm working on a menu driven program that has users basically keep track of their assignment tasks and due dates. My program deals with a text file titled "tasks.txt", and the user has 3 options for interacting with the text file: Enter a new task, Display all the tasks in the file, or Find a task by course. My program runs relatively nicely except that it doesn't seem to be able to fully interact with the file.
Below is my output/input file: tasks.txt
CS162;Finish Project 2;04/10/2015
CS162;Finish Project 3;04/20/2015
CS162;Finish Project 4;05/10/2015

Here's my code:
#define _CRT_SECURE_NO_WARNINGS
#include <cstring>
#include <fstream>
#include <iostream>
using namespace std;
//Global constants
const int CAP = 100;
const int MAXCHAR = 201; // Task description can be a max of 200 characters in case its a long description (ie: specific instructions)
//Task struct
struct Task
{
char courseName[MAXCHAR];
char taskDescrip[MAXCHAR];
char dueDate[MAXCHAR];
};
//function prototypes
void openFile(ifstream &inFile);
void loadData(ifstream &inFile, Task tasks[], int &listSize);
void exeCommand(char option, Task tasks[], int &listSize);
void displayMenu();
char readOption();
void getUserTask(Task &tempTask);
void addUserTask(Task tasks[], int &listSize, Task tempTask);
void printTasks(Task tasks[], const int listSize);
void writeFile(ofstream &outFile, Task tasks[], const int listSize);
//Main function
int main()
{
int listSize = 0; //keep track of list size
ofstream outFile; //output file stream variable
ifstream inFile; //input file stream variable
Task tasks[CAP]; //array of tasks
char option; // user menu input for option
openFile(inFile); //open up tasks.txt

do
{
displayMenu();
option = readOption();
exeCommand(option, tasks, listSize);
} while (tolower(option) != 'q');
return 0;
}
//open the file
void openFile(ifstream &inFile)
{
inFile.open("tasks.txt");
if (!inFile)
{
cout << "file not open" << endl;
exit(0);
}
}
//load the data from the file to the array
// parameters:
void loadData(ifstream &inFile, Task tasks[], int &listSize)
{
while (!inFile.eof())
{
inFile.get(tasks[listSize].courseName, MAXCHAR, ';');
inFile.ignore(200, ';');
inFile.get(tasks[listSize].taskDescrip, MAXCHAR, ';');
inFile.ignore(200, ';');
inFile.get(tasks[listSize].dueDate, MAXCHAR, ';');
inFile.ignore(200, '\n');
listSize++;
}
inFile.close();
}
void displayMenu()
{
cout << "Welcome to TaskTracker v.1" << endl;

char readOption()

cin.get(option);
cin.ignore(100, '\n');
return option;
}
void exeCommand(char option, Task tasks[], int &listSize)
{
Task tempTask;// created object tempTask
switch (tolower(option))
{
case 'a':

}
void getUserTask(Task &tempTask)
{

cin.get(tempTask.courseName, MAXCHAR);//user enters the course name
cin.ignore(100, '\n');//ignores the next 100 characters or until newline
cout << "Please enter a brief description of your task (less than 101 characters): ";

}
void addUserTask(Task tasks[], int &listSize, Task tempTask)
{
tasks[listSize++] = tempTask;
}
//prints the task list
void printTasks(Task tasks[], const int listSize)
{
for (int i = 0; i < listSize; i++)
{
cout << tasks[i].courseName << ';' << tasks[i].taskDescrip << ';' << tasks[i].dueDate << endl;
}
}
//writes to file at the end of the program
void writeFile(ofstream &outFile, Task tasks[], const int listSize)
{
outFile.open("tasks.txt");
for (int i = 0; i < listSize; i++)
{
outFile << tasks[i].courseName << ';' << tasks[i].taskDescrip << ';' << tasks[i].dueDate << endl;
}
return;
}
The following is the output in the debugger:
Welcome to TaskTracker v.1
(a) Add a task
(l) List all tasks
(f) Find any tasks by course
(q) Quit
Please make a selection: l
You chose print tasks!

Welcome to TaskTracker v.1
(a) Add a task
(l) List all tasks
(f) Find any tasks by course
(q) Quit
I have been peeling over the code for hours now and searching online for similar cases, but it seems like my fstream is able to read and load the course name for every line, but skips the task description and due date for every other task. Can someone please point me in the right direction?
The Add option of the menu seems to do okay with loading new user input tasks into the buffer, but the writefile function thats supposed to save all tasks in the buffer to the output file doesn't seem to work either.
I'll continue to look for a solution but any help is greatly appreciated!
