Passing variables
Passing by value:
Issues about c
C wants to see a function declared before it’s invoked
How to fix this
If you warn c by providing a function template it will stop panicking
Passing by reference
Sometimes you want your code modify the original variables.
Passing by reference can do this
Scope of variables
What happens if we try to print “c” from main?
Why is this?
Every function has its own stack frame.
