• make: compile and run the program
• make test: run tests!
• make debug: compile without optimization and open gdb debugger
• make verbose: compile normally and run it with Valgrind to see more verbose error output
• make clean: removes compiled files and clear the screen

1. Visit random/test.c and create an analog file for the functionality that you want to test.
2. Visit test.conf.c and add the proper header file of the new functionality being tested and add the SUITE to the suite list and as an extern variable.
3. Run make test and be happy!

Is important to know how much time does the program takes to calculate all the iterations.

To measure it run:

make
time ./main

Focus on the real field, that is the time that it took the program to return.

C is pretty good at making a lot of calculations, but its really slow (as you might suspect) on printing values, so avoid making a lot of printing because its very time consuming.

The VM comes with GDB which is the debugger for C. Use GDB instead of old printf.

To debug:

# Run debug make task
make debug
# On gdb console
# Create a breakpoint on line 74
break 74
# run the program
run
# It will stop on the breakpoint
# you can inspect any variable at this point
print some_var
# Continue
cont
# Repeat and Enjoy!
