Computer Program Statement

A Computer Program Statement is a computer program statement in a computer program (expressed in some programming language).

• AKA: Program Statement.
• Context:
  • It can range from being an Imperative Programming Statement to being a Declarative Programming Statement.
  • It can be a Data Statement, such as: a Data Structure Definition Statement, a Data Manipulation Statement, a Data Access Statement.
  • It can be Conditional Logic Statement.
• Example(s):
  • a Java Program Statement.
  • a SQL Statement.
  • a Perl Statement.
• Counter-Example(s):
  • a Mathematical Equation.
• See: Computer Program, Statement, Programming Statement.

  • In computer programming a statement is the smallest standalone element of an imperative programming language. A program written in such a language is formed by a sequence of one or more statements. A statement will 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. 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
