 ## Measuring FPS and Elapsed time
 I first use **chrono** liberary to measure the time but found that it's hard to convert to seconds unit for calculating FPS. So, I use **ctime**.
 ```c
-# in utils.cpp
+// in utils.cpp
 #include <ctime>
 
 numFrames = 100;
 
 clock_t start = clock();
-# some function here

 clock_t end = clock();
 
 double elapsed_secs = double(end - start) / CLOCKS_PER_SEC;
