This paper proposes a simple operational semanticsof pGCL, Dijkstra's guarded command language extended withprobabilistic choice, and relates this to pGCL's wp-semantics byMcIver and Morgan.

The design of programming languages has always been an important topic in the field of programming language theory. However, most attention on programming language research focuses on compiler ...

In this text we’ll talk about syntax and semantics, so it’s important that we understand what these terms mean, particularly in the context of computer programming. In a (natural) language course—say ...
