Unless a language has strict rules regarding naming conventions, how we name our variables is really a matter of personal style. In C and C++ we generally prefer all lowercase with underscores separating each word as this helps readability and retains consistency with standard library conventions. Using a leading capital typically denotes something of importance, but is usually applied to a user-defined type rather than to a variable. Uppercase names are generally avoided because macros are conventionally named using all uppercase so they stand out. Other languages have other conventions, but a leading capital typically has no real meaning unless it is dictated by some language rule.

Is it necessary to initialize accumulator variables?
If it isn't, then you don't know for sure what value it will start at in some languages. Thus, your count will be wildly inaccurate. In other languages, it will just generate an error if you forget to initialize. Two steps: 1. It is critical that variables be properly initialized. 2. Counter-variables are variables.
What are all the variables?
There are 'constant variables' , 'independant variables' and 'dependent variables' Constant Variable- things in the experimment that should be kept the same Independant variables- something that can be varied in an experiment Dependant variable- something that can be affected
What is the default initial value for all numeric types?
If they are instance variables the default initial value is 0. If they are method local variables, they are null and must be initialized to some value before they are used
Are C variables initialized to 0 by default?
Only global/static variables are, local variables aren't.
Who created variables?
The inventor of variables is THEEZ NUTZ!
