Lowercase and uppercase variables declaration

[Lee Jia]

Hi,

Can I declare similar alpahet in lowercase and uppercase, example m and M? 

I wish to use the same alpabet as variable , so can I differeciate both variables by using lowercase and uppercase?

You can, but be careful that you don't accidently use the wrong variable in your code.

I think that normally, most people capitalise the first letter to denote and help recognise a globalscope variable.
Lowercase first letter for a locally declared variable.
