Common variable names in different languages

I see a lot of different styles of variable names used in different kind of languages. Sometimes these names are lowercase and using underscores (i.e. test_var) and other times I see variables like testVar.

Is there a specific reason why programmers use different variable name styles in different languages?

Solution

  • It's really just the convention for that programming language.

    For example, most Java programs use camel-casing (testVar) while a lot of C programs use _ to seperate words (test_var).

    It's completely the choice of the programmer, but most languages have "standard" naming conventions.
