How C# Differs From C
If you have been exposed to C, or if you are an experienced C
programmer, you might be interested in the main differences between C#
and C:
1. C# does not usually make use of pointers. You can only increment,
or decrement a variable as if it were an actual memory pointer
inside a special unsafe block.
2. You can declare variables anywhere inside a method you want to;
they don’t have to be at the beginning of the method.
3. You don’t have to declare an object before you use it; you can
define it just as you need it.
4. C# has a somewhat different definition of the struct types, and does
not support the idea of a union at all.
5. C# has enumerated types, which allow a series of named values,
such as colors or day names, to be assigned sequential numbers, but
the syntax is rather different.
6. C# does not have bitfields: variables that take up less than a byte of
storage.
7. C# does not allow variable length argument lists. You have to
define a method for each number and type of argument. However C# allows for the last argument of a function to be a variable parameter array.
