There is an argument that you should only initialise variables at the
point of declaration if you know what value they should take; so that
the compiler can detect the use of uninitialised variables.
If you always initialize variables, even if you don't know what value
they should take, the compiler can't help you if you forget to assign
the correct value.
Personally I always try hard not to declare an uninitialised variable.
