Recent examples, such as Facebook’s React GUI framework have shown, how modelling the view as a func- tional projection from the application state to a visual representation can reduce the number of interacting objects and thus help to improve the reliabiliy of the system. -

7. Control Flow First?
Copyright (C) R.A. van Engelen, FSU Department of Computer Science, 2000-2004 Ordering Program Execution: What is Done 7. Control Flow First? Overview Categories for specifying ordering in programming languages: Expressions 1. Sequencing: the execution of statements and evaluation of Evaluation order expressions is usually in the order in which they appear in a Assignments program text Structured and unstructured flow constructs 2. Selection (or alternation): a run-time condition determines the Goto's choice among two or more statements or expressions Sequencing 3. Iteration: a statement is repeated a number of times or until a Selection run-time condition is met Iteration and iterators 4. Procedural abstraction: subroutines encapsulate collections of Recursion statements and subroutine calls can be treated as single Nondeterminacy statements 5. Recursion: subroutines which call themselves directly or indirectly to solve a problem, where the problem is typically defined in terms of simpler versions of itself 6. Concurrency: two or more program fragments executed in parallel, either on separate processors or interleaved on a single processor Note: Study Chapter 6 of the textbook except Section 7. Nondeterminacy: the execution order among alternative 6.6.2. constructs is deliberately left unspecified, indicating that any alternative will lead to a correct result Expression Syntax Expression Evaluation Ordering: Precedence An expression consists of and Associativity An atomic object, e.g. number or variable The use of infix, prefix, and postfix notation leads to ambiguity An operator applied to a collection of operands (or as to what is an operand of what arguments) which are expressions Fortran example: a+b*c**d**e/f Common syntactic forms for operators: The choice among alternative evaluation orders depends on Function call notation, e.g. -

Change the description and compiler actions for poke. Change the description for swp. Change the compiler actions for call and callr. Changes shown in green. v0.14, changes from 0.13 Add peek, poke and swp instructions. Change popm compiler actions. Change callr compiler actions. Other small changes to wording. Changes are shown in blue. v0.13, changes from 0.12 Add a count field to subr, call and callr to simplify code generation. Changes are shown in red. v0.12 Changes from 0.11. Added a callr statement that takes a return type. Fix the generated code for this and for call to allow arguments to be pushed by the call. Add a retr that returns a value and update the reg. v0.11: changes from 0.10. Put typing into push operators. Put opcodes for compare operators. fix actions for call. Make declarations reserve a stack location. Remove redundant store instruction (popv does the same thing.) v0.10: changes from 0.0. Comparison operators (cmpe, cmplt, cmpgt) added. jump conditional (jmpc) added. bytecode values added. -

Programming Basics - FORTRAN 77
CWCS Workshop May 2005 Programming Basics - FORTRAN 77 http://www.physics.nau.edu/~bowman/PHY520/F77tutor/tutorial_77.html Program Organization A FORTRAN program is just a sequence of lines of plain text. This is called the source code. The text has to follow certain rules (syntax) to be a valid FORTRAN program. We start by looking at a simple example: program circle real r, area, pi c This program reads a real number r and prints c the area of a circle with radius r. write (*,*) 'Give radius r:' read (*,*) r pi = atan(1.0e0)*4.0e0 area = pi*r*r write (*,*) 'Area = ', area end A FORTRAN program generally consists of a main program and possibly several subprograms (i.e., functions or subroutines). The structure of a main program is: program name declarations statements end Note: Words that are in italics should not be taken as literal text, but rather as a description of what belongs in their place. FORTRAN is not case-sensitive, so "X" and "x" are the same variable. Blank spaces are ignored in Fortran 77. If you remove all blanks in a Fortran 77 program, the program is still acceptable to a compiler but almost unreadable to humans. Column position rules Fortran 77 is not a free-format language, but has a very strict set of rules for how the source code should be formatted. The most important rules are the column position rules: Col. 1: Blank, or a "c" or "*" for comments Col. 1-5: Blank or statement label Col. 6: Blank or a "+" for continuation of previous line Col. -

Ignore registers (for our purposes) and details of instruction set Data segment ! Stack contains data related to block entry/exit ! Heap contains data of varying lifetime ! Environment pointer points to current stack position ■ Block entry: add new activation record to stack ■ Block exit: remove most recent activation record Control Flow 6 Control flow in imperative languages is most often designed to be sequential ! Instructions executed in order they are written ! Some also support concurrent execution (Java) But… Goto in C # include <stdio.h> int main(){ float num,average,sum; int i,n; printf("Maximum no. of inputs: "); scanf("%d",&n); for(i=1;i<=n;++i){ -

C Style and Coding Standards
-- -- -1- C Style and Coding Standards Glenn Skinner Suryakanta Shah Bill Shannon AT&T Information System Sun Microsystems ABSTRACT This document describes a set of coding standards and recommendations for programs written in the C language at AT&T and Sun Microsystems. The purpose of having these standards is to facilitate sharing of each other’s code, as well as to enable construction of tools (e.g., editors, formatters). Through the use of these tools, programmers will be helped in the development of their programs. This document is based on a similar document written by L.W. Cannon, R.A. Elliott, L.W. Kirchhoff, J.H. Miller, J.M. Milner, R.W. Mitze, E.P. Schan, N.O. Whittington at Bell Labs. -- -- -2- C Style and Coding Standards Glenn Skinner Suryakanta Shah Bill Shannon AT&T Information System Sun Microsystems 1. Introduction The scope of this document is the coding style used at AT&T and Sun in writing C programs. A common coding style makes it easier for several people to cooperate in the development of the same program. Using uniform coding style to develop systems will improve readability and facilitate maintenance. In addition, it will enable the construction of tools that incorporate knowledge of these standards to help programmers in the development of programs. For certain style issues, such as the number of spaces used for indentation and the format of variable declarations, no clear consensus exists. In these cases, we have documented the various styles that are most frequently used. We strongly recommend, however, that within a particular project, and certainly within a package or module, only one style be employed.
