Write a program that opens a local file C:\DataDirectory\data.txt reads in the data into your program without removing the data from the file and appends new data onto the end of the existing data in the program, and then appends the new data onto the existing data within the file. For example, if the data file originally contained the following data: Hello Then when your program is done, it should say: HelloHello my name is Bob Also, you must utilize exception handing technique to validate that the file has been open, and offer the user a chance to enter a correct filename until the file is found. Hint: Use the overloaded open functions, or use random access methodology. Save program as a cpp file type. .

1. Write a program that opens a local file
C:DataDirectorydata.txt reads in the data into your program
without removing the data from the file and appends new data
onto the end of the existing data in the program, and then
appends the new data onto the existing data within the file.
For example, if the data file originally contained the following
data:
Hello
Then when your program is done, it should say:
HelloHello my name is Bob
Also, you must utilize exception handing technique to validate
that the file has been open, and offer the user a chance to enter
a correct filename until the file is found.
Hint: Use the overloaded open functions, or use random access
methodology.
Save program as a cpp file type.
