How to use valgrind

valgrind --leak-check=full 
         --show-leak-kinds=all 
         --track-origins=yes 
         --verbose 
         --log-file=valgrind-out.txt 
         ./executable exampleParam1
         
# Their meanings:
#  --leak-check=full: "each individual leak will be shown in detail"
#  --show-leak-kinds=all: Show all of "definite, indirect, possible, reachable" leak kinds in the "full" report.
#  --track-origins=yes: Favor useful output over speed. This tracks the origins of uninitialized values, which could be very useful for memory errors. Consider turning off if Valgrind is unacceptably slow.
#  --verbose: Can tell you about unusual behavior of your program. Repeat for more verbosity.
#  --log-file: Write to a file. Useful when output exceeds terminal space.
