Software Statement

A Software Statement is a formal statement that abides by a programming language.

• Context:
  • It can (typically) be a Software Program Statement (within a software program).
  • It can range from being an Imperative Programming Statement to being a Declarative Programming Statement.
  • It can (often) reference a Software Variable and a Software Operator.
• Example(s):
  • An Imperative Programming Statement, such as: do { println(x); x += 1} while (x < 5), a Scala statement.
  • A Declarative Programming Statement, such as: SELECT col2 AS age, COUNT(*) FROM table GROUP BY col2, a SQL SELECT statement.
  • a Scala statement, Python Statement, Perl Statement, ...
  • a Software Proposition, such as a software assertion.
  • a Conditional Software Expression.
  • …
• Counter-Example(s):
  • a Software Expression.
  • Shell Command.
  • a Formal Statement.
  • a Mathematical Statement.
• See: Pseudocode, Software Expression Side Effect, Software Function, Order of Operations, Software State, Expression (Programming), Side Effect (Programming).

  • In computer programming a statement is the smallest standalone element of an imperative programming language that expresses some action to be carried out. It is an instruction written in a high-level language that commands the computer to perform a specified action. A program written in such a language is formed by a sequence of one or more statements. A statement may have internal components (e.g., expressions). Many languages (e.g. C) make a distinction between statements and definitions, with a statement only containing executable code and a definition declaring an identifier, while an expression evaluates to a value only. A distinction can also be made between simple and compound statements; the latter may contain statements as components.

  • The following are the major generic kinds of statements with examples in typical imperative languages:
    • assignment: A:= A + 1
    • call: CLEARSCREEN()
    • return: return 5;
    • goto: goto 1
    • assertion: assert(ptr != NULL);
    • block: begin integer NUMBER; WRITE('Number? '); READLN(NUMBER); A:= A*NUMBER end
    • if-statement: if A > 3 then WRITELN(A) else WRITELN("NOT YET"); end
    • switch-statement: switch (c) { case 'a': alert(); break; case 'q': quit(); break; }
    • while-loop: while NOT EOF DO begin READLN end
    • do-loop: do { computation(&i); } while (i < 10);
    • for-loop: for A:=1 to 10 do WRITELN(A) end
