You've been hired by Faraway Fantasies to write a C++ console application that reads data from file NearestStars.txt. The file contains the ten nearest stars to Earth. It has a header line and ten detail lines. Each detail line contains two tokens:
Star name
Distance from Earth in light minutes (Sun) and light years (all other stars).
Place the file in a folder where your development tool can locate it, or place the file in a data folder and use a path to the file. In the app, attempt to open the file. If it doesn't open, print an error message. If it does open, print a file-reading message, and three column headers:
Star
Distance
Time (described next)
Use a while loop to read through the file. For each detail line, read the star name and distance. Assume there is a spacecraft that travels 0.4 light years per hour (yes, that's fast; is it possible? Ask Jacob.). Calculate the time to travel to the star. Note that the distance to the Sun is in light minutes so the time calculation will have to use a factor of 525,600 minutes per year. Use formatted output manipulators (setw, left/right) to print in one row the following:
Star
Distance
Time
Track the number of lines read and print the count after the loop. Define constants for the input file name, spacecraft speed, minutes per year, and the column widths. Format all real numbers to six decimal places. See sample app TextFileInput-OneTokenPerRead.cpp on Canvas. The output should look like this:
