Length – If too short, they cannot be connotative – Language examples: . FORTRAN I: maximum 6 . COBOL: maximum 30 . C99: no limit but only the first 63 are significant; also, external names are limited to a maximum of 31 . C# and Java: no limit, and all characters are significant . C++: no limit, but implementers often impose a length limitation because they do not want the symbol table in which identifiers are stored during compilation to be too large and also to simplify the maintenance of that table.

  • 7. Functions in PHP – II
    7. Functions in PHP – II Scope of variables in Function Scope of variable is the part of PHP script where the variable can be accessed or used. PHP supports three different scopes for a variable. These scopes are 1. Local 2. Global 3. Static A variable declared within the function has local scope. That means this variable is only used within the function body. This variable is not used outside the function. To demonstrate the concept, let us take an example. // local variable scope function localscope() { $var = 5; //local scope echo '<br> The value of $var inside the function is: '. $var; } localscope(); // call the function // using $var outside the function will generate an error echo '<br> The value of $var inside the function is: '. $var; The output will be: The value of $var inside the function is: 5 ( ! ) Notice: Undefined variable: var in H:\wamp\www\PathshalaWAD\function\function localscope demo.php on line 12 Call Stack # Time Memory Function Location 1 0.0003 240416 {main}( ) ..\function localscope demo.php:0 The value of $var inside the function is: Page 1 of 7 If a variable is defined outside of the function, then the variable scope is global. By default, a global scope variable is only available to code that runs at global level. That means, it is not available inside a function. Following example demonstrate it. <?php //variable scope is global $globalscope = 20; // local variable scope function localscope() { echo '<br> The value of global scope variable is :'.$globalscope; } localscope(); // call the function // using $var outside the function will generate an error echo '<br> The value of $globalscope outside the function is: '.

  • Object Lifetimes In
    Object Lifetimes in Tcl - Uses, Misuses, Limitations By Phil Brooks - Mentor – A Siemens Corporation Presented at the 25 nd annual Tcl/Tk conference, Houston Texas, November 2018 Mentor – A Siemens Corporation 8005 Boeckman Road Wilsonville, Oregon 97070 [email protected] Abstract: The management of the lifetime of an object in Tcl presents a number of unique challenges. In the C++ world, the technique of Resource Allocation is Initialization (RAII) is commonly used to control the lifetime of certain objects. With this technique, an object on the call stack is used to insure proper cleanup of a resource. When the object goes out of scope, the resource is released. It presents a low overhead mechanism for a garbage collection like facility without the complication of more complete garbage collection systems. Tcl doesn't have a similar direct capability, and the need for it has resulted in two techniques that are commonly used to substitute for the capability. The techniques are: 1) Use of the trace command to catch unset of a variable. 2) Mis-use of the lifetime of a Tcl_Obj created with Tcl_NewObj. Each of these techniques has drawbacks. The primary issue with the trace technique is that it requires the user of an object to arrange for explicit destruction of the object. This makes the interface more error prone. The mis-use of lifetime of a Tcl_Obj is subject to premature cleanup of the resource if the object is shimmered to a string for any reason. This paper surveys these lifetime management patterns and demonstrates the use of a new user level technique for lifetime management.

  • Chapter 5. Using Tcl/Tk
    The Almagest 5-1 Chapter 5. Using Tcl/Tk Authors: Edward A. Lee Other Contributors: Brian L. Evans Wei-Jen Huang Alan Kamas Kennard White 5.1 Introduction Tcl is an interpreted “tool command language” designed by John Ousterhout while at UC Berkeley. Tk is an associated X window toolkit. Both have been integrated into Ptolemy. Parts of the graphical user interface and all of the textual interpreter ptcl are designed using them. Several of the stars in the standard star library also use Tcl/Tk. This chapter explains how to use the most basic of these stars, TclScript, as well how to design such stars from scratch. It is possible to define very sophisticated, totally customized user interfaces using this mechanism. In this chapter, we assume the reader is familiar with the Tcl language. Documentation is provided along with the Ptolemy distribution in the $PTOLEMY/tcltk/itcl/man direc- tory in Unix man page format. HTML format documentation is available from the other.src tar file in $PTOLEMY/src/tcltk. Up-to-date documentation and software releases are available by on the SunScript web page at http://www.sunscript.com. There is also a newsgroup called comp.lang.tcl. This news group accumulates a list of frequently asked questions about Tcl which is available http://www.teraform.com/%7Elvirden/tcl-faq/. The principal use of Tcl/Tk in Ptolemy is to customize the user interface. Stars can be created that interact with the user in specialized ways, by creating customized displays or by soliciting graphical inputs. 5.2 Writing Tcl/Tk scripts for the TclScript star Several of the domains in Ptolemy have a star called TclScript.

  • Function Components and Arguments Passing in Cpp
    FUNCTION COMPONENTS AND ARGUMENTS PASSING IN CPP The General Form of a Function The general form of a function is ret-type function-name(parameter list) { body of the function } The ret-type specifies the type of data that the function returns.Afunction may return any type of data except an array. The parameter list is a comma-separated list of variable names and their associated types that receive the values of the arguments when the function is called.Afunction may be without parameters, in which case the parameter list is empty. However, even if there are no parameters, the parentheses are still required. In variable declarations, you can declare many variables to be of a common type by using a comma- separated list of variable names. In contrast, all function parameters must be declared individually, each including both the type and name. That is, the parameter declaration list for a function takes this general form: f(type varname1, type varname2, . , type varnameN) For example, here are correct and incorrect function parameter declarations: f(int i, int k, int j) /* correct */ f(int i, k, float j) /* incorrect */ Scope Rules of Functions The scope rules of a language are the rules that govern whether a piece of code knows about or has access to another piece of code or data. Each function is a discrete block of code. Afunction's code is private to that function and cannot be accessed by any statement in any other function except through a call to that function. (For instance, you cannot use goto to jump into the middle of another function.) The code that constitutes the body of a function is hidden from the rest of the program and, unless it uses global variables or data, it can neither affect nor be affected by other parts of the program.

  • Subprograms: Local Variables
    Subprograms: Local Variables ICS312 Machine-Level and Systems Programming Henri Casanova ([email protected]) Local Variables in Subprograms In all the examples we have seen so far, the subprograms were able to do their work using only registers But sometimes, a subprogram’s needs are beyond the set of available registers and some data must be kept in memory Just think of all subprograms you wrote that used more than 6 local variables (EAX, EBX, ECX, EDX, ESI, EDI) One possibility could be to declare a small .bss segment for each subprogram, to reserve memory space for all local variables Drawback #1: memory waste This reserved memory consumes memory space for the entire duration of the execution even if the subprogram is only active for a tiny fraction of the execution time (or never!) Drawback #2: subprograms are not reentrant Re-entrant subprogram A subprogram is active if it has been called but the RET instruction hasn’t been executed yet A subprogram is reentrant if it can be called from anywhere in the program This implies that the program can call itself, directly or indirectly, which enables recursion e.g., f calls g, which calls h, which calls f At a given time, two or more instances of a subprogram can be active Two or more activation records for this subprogram on the stack If we store the local variables of a subprogram in the .bss segment, then there can only be one activation! Otherwise activation #2 could corrupt the local variables of the activation #1 Therefore, with our current scheme for storing local

    Introduction to Computer Science and Programming in C Session 7: September 23, 2008 Columbia University Announcements Homework 1 due. Homework 2 out this afternoon. Due 10/7 2 Review Conditionals: if (<condition>) switch (variable) Loops: while (<condition>) for (<init>; <condition>; <count>) 3 Today Functions Variable Scope Recursion 4 Functions We’ve seen functions already int main() printf() But we can write our own functions too! 5 Function Syntax <return type> myFunction(<arguments>) { /* instructions to execute function */ } int multiply(int x, int,y) { return x*y; } Note: functions can return type void, which essentially means they return nothing, like printf() 6 Abstraction Revisited Functions allow us to abstract away algorithms Once a function is written and tested, you can forget about how it works. We can describe the logic at a higher level. 7 Example /* if we have three arrays A[10], B[10], C[10] */ /* Check if they are equal */ int check = 1; for (i=0; i<10; i++) { check = check && (A[i]==B[i]); } for (i=0; i<10; i++) { check = check && (B[i]==C[i]); } 8 Example int arrayEqual(int X[], int Y[], int N) { int i, check=1; for (i=0; i<N; i++) { check = check && (X[i]==Y[i]); } } /* main code */ int check; check = arrayEqual(A,B,10) && arrayEqual(B,C,10); 9 Scope float half(float x) scope - area of program where { variable is valid. return x/2; } global variable - variable is valid everywhere int main() { float x=10.0, y; local variable - only valid within block y = half(x); block – area of code enclosed /*what is x? ...*/ by {} x is 10 We have only been using local variables so far in class Global Variables Declared outside of any functions #include <stdio.h> int count; /* a global variable */ int someFunction() { ..

  • Software II: Principles of Programming Languages Introduction
    Software II: Principles of Programming Languages Lecture 5 – Names, Bindings, and Scopes Introduction • Imperative languages are abstractions of von Neumann architecture – Memory – Processor • Variables are characterized by attributes – To design a type, must consider scope, lifetime, type checking, initialization, and type compatibility Names • Design issues for names: – Are names case sensitive? – Are special words reserved words or keywords? Names (continued) • Length – If too short, they cannot be connotative – Language examples: • FORTRAN 95: maximum of 31 (only 6 in FORTRAN IV) • C99: no limit but only the first 63 are significant; also, external names are limited to a maximum of 31 (only 8 are significant K&R C ) • C#, Ada, and Java: no limit, and all are significant • C++: no limit, but implementers often impose one Names (continued) • Special characters – PHP: all variable names must begin with dollar signs – Perl: all variable names begin with special characters, which specify the variable’s type – Ruby: variable names that begin with @ are instance variables; those that begin with @@ are class variables Names (continued) • Case sensitivity – Disadvantage: readability (names that look alike are different) • Names in the C-based languages are case sensitive • Names in others are not • Worse in C++, Java, and C# because predefined names are mixed case (e.g. IndexOutOfBoundsException ) Names (continued) • Special words – An aid to readability; used to delimit or separate statement clauses • A keyword is a word that is special only
