A plaster cast is a copy of a sculpture, which is cast in plaster. A plaster cast can accurately reproduce the details of the original sculpture, but is usually much less durable. It is often used as a stage in the casting process.
Concatenate Strings in C#: + Operator vs. String.Concat vs. StringBuilder. In the source code of almost any software application individual strings are concatenated into one string. To implement a string concatenation is thus something absolutely rudimentary and should belong to the repertoire of every software developer. In C# there are several options available to connect strings.
In many programming languages, string concatenation is a binary infix operator. The + (plus) operator is often overloaded to denote concatenation for string arguments: Hello,  + World has the value Hello, World. In other languages there is a separate operator, particularly to specify implicit type conversion to string, as opposed to more complicated behavior for generic plus. Examples include . in Edinburgh IMP, Perl, and PHP, and & in Ada and Visual Basic. Other syntax exists, like || in PL/I and Oracle Database SQL.
