Why are many languages case sensitive?

Question

Why are many languages case sensitive?

Is it simply a matter of inheritance? C++ is case-sensitive because C is, Java is case-sensitive because C++ is, etc.? Or is t

Answer 1

I think having a case-sensitive language ENCOURAGES people to write poor code.

Const SHOESIZE = 9

Class ShoeSize

ShoeSize.shoesize = SHOESIZE

call shoeSize(ShoeSize);

function shoeSize(SHOEsize)
{
   int ShoeSIZE = 10
   return ShoeSize
}

Duh. You couldn't think of a better variable name than "ShoeSize" for the different purposes? There is a billion different words you could use, but you choose to just keep using ShoeSize instead?
