1.5) You have been provided with a text file called InterestingFacts.txt. It consists of 14 interesting facts about the Olympics. Each line starts with a year followed by a # and then the fact.  Here is a sample of the text file: (note that the lines are wrapped here but not in the actual file.)   1998#Surya Bonaly did a move which was banned  – a backflip landing on one blade. 2012#Paul McCartney earned 1 pound for his performance at the opening ceremony. 2002#Steven Bradbury was last until a collision occurred and left him the only one to finish, and so he got gold. Create two global arrays. one for the year as an integer and one for the fact. These will be parallel arrays. (3) Jy het ook ‘n tekslêer naamlik InterestingFacts.txt gekry. Dit bestaan uit 14 interessante feite oor die Olimpiese Spele. Elke reël begin met ‘n jaar gevolg deur ‘n # en dan die feit. Hier is ‘n voorbeeld van die tekslêer in Engels: (let op dat die lyne in die voorbeeld outomaties oorloop, maar nie in die werklike lêer nie.) 1998#Surya Bonaly did a move which was banned  – a backflip landing on one blade. 2012#Paul McCartney earned 1 pound for his performance at the opening ceremony. 2002#Steven Bradbury was last until a collision occurred and left him the only one to finish, and so he got gold. Skep twee globale skikkings. een vir die jaar as ‘n heelgetal en een vir die feit. Dit moet parallelle skikkings wees. 1.6) Create a user defined procedure which will read in the text file into the two arrays,. The fact should not include the #. Check if the file exists and if it does not then display a suitable message. (10) Skep ‘n gebruikersgedefinieerde prosedure wat in die tekslêer in die twee skikkings sal lees. Die feit moet nie die # insluit nie. Kyk of die lêer bestaan en as dit nie bestaan nie, dan moet ‘n geskikte boodskap vertoon word.
