using c++

Given a text file containing unknown number of lines, each line containing three integer values representing the height of a building in (Yard foot inches) separated by space. Write a well-documented C++ program that

Reads the three values from the file,

If any of the read values is greater than 2000, prints on the screen an error message: Error: invalid building length.! .

Otherwise, calculates the building length in inches, where one yard is 3 feet, and foot is 12 inches,

Sends to another file both length values: the read and the calculated as shown below.

Repeats steps (1-4) until a negative value is encountered.

For example, if the read values are (71 2 6), then your program must send to a new file the following:

The height of a building in YD:FT:IN format = 71:2:6

The height of a building in inches = 2586
