// close files

inFile.close();

outFile.close();

// freezen screen

cin >> junk;

return (0);

This is my homework guidline:

Modify your Retire.cpp program to accept its input from a disk file named "Retire.dat" and display the output to the screen.

Then modify it again to send the output to a disk file name "retire.out".

And I did above code, and my inFile is retire.dat which is

Sumin
21

then I have a file will become outFile, but it is strange.

I have a result that

"Well, Sumin can retire in 48 years."

but my file's result is

Well, can retire in -858993433 years.

How do I fix it?

=============================================
I am able to get the Output with my own correct files, The error could be file is not found, So you are getting this garbage values.

I have added statements , such that if you get file not found. You will see error
