IN C++

The text file is the 5 lines below

1 1 1

1.2 -2.3 0.4

-2 -3 -4

+0 -2 8.85

2.345

 

Write a function to read one set of values from the file. Use reference parameters (NOT an
array!) to get the values out of the function and the function’s return value to indicate whether or
not the function was able to correctly read three values. Return the 'stop' code on end-of-file
before reading the third value. The only data error you must deal with here is too few values on
the line, e.g., the line has a and b values only but no c value. You may assume that the last line
in the file is the only one with an error (if any error exists), and your function should return a
code to make the program stop processing after this error. This restriction allows you to use
stream extraction to read the file, rather than reading lines and parsing them yourself. This
function MAY NOT try to read all the lines in the file, just read one line per call to the function.
