 ### 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: File IO
 *estimate: 45 minutes*
 
-For the remainder of the lab time, work on the Crash Course in C++
+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.
-Exercises. Discuss the exercises with your lab study group classmates and ask
-your TA and mentors lots of questions!
 
-### To complete Checkpoint 3 (and the entire lab):
+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). 
-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.
+### 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.
