### To complete Checkpoint 2:
Show a TA or mentor your program. Be ready to demonstrate that your program works with other input requested by the TA or mentor.
## Checkpoint 3
## Checkpoint 3: File IO
*estimate: 45 minutes*
For the remainder of the lab time, work on the Crash Course in C++
Exercises. Discuss the exercises with your lab study group classmates and ask
your TA and mentors lots of questions!
In lecture we talked about how to use the STL file stream library fstream to read data from a file and/or write the output to a file. Let's do some exercises.
### To complete Checkpoint 3 (and the entire lab):
About 10 minutes before the end of lab the TA and mentors will make a final visit to each study group and check you off. Please be ready to quickly update them
on your progress.
Write a C++ program which reads this [json file](users.json), and print all user names into an output file called output.txt. Your output file must be the same as this [sample output file](sample_output.txt).
### To complete Checkpoint 3:
Show a TA or mentor your program. Your program must produce the right output and you must be able to explain your program.
