solve by 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 1. Reads the three values from the file. 2. If any of the read values is greater than 2000, prints on the screen an error message: "Error walid building length 3. Otherwise calculates the building length in inches, where one yard is 3 feet, and foot is 12 inches, 4. Sends to another file both length values the read and the calculated as shown below. 5. Repeats steps (1-4) until a negative value is encountered. For example, if the read values are (7126), then your program must send to a new le the following The height of a building in YD:FT:IN format 71:2:6 . The height of a building in inches 2586
