I am asked to implement a calendar with the following specifications

* Add an event to the calendar
* Display events for a specific calendar date.
* Display the whole calendar.
* Delete the event from the calendar.
* Writes the events of a calendar to a text file.
* Reads the events of a calendar from a text file.

I have a problem with reading the data from a text file. I have a correct syntax. However, my program crashes while reading the events from a text file, and exactly inside the for loop. (Please note that there are some debugging statements inside the `ReadfromText`function)
Here is the code:

```
        /************************************************************************************************

    Output file: None
    Description: This calendar program is mainly a menu interactive program that prompts
                 the user for a date and its events, then the entry is stored in its appropriate
                 place inside an array of structures.
                 This program handles 5 main operations:
                    . Add an event to the calendar.
                    . Display events for a specific calendar date.
                    . Display the whole calendar.
                    . Delete the event from the calendar.
                    . Writes the events of a calendar to a text file.
                    . Reads the events of a calendar from a text file.
