Re: Scoping Issues 13 Years Ago by Rashakil Fol Dynamic scoping is just global or thread-local variables with some cheesewiz. Static Scoping and Dynamic Scoping 14 Years Ago by jyotishkardey Can u plz. explain static scoping and dynamic scoping in c++?? Re: Static Scoping and Dynamic Scoping 14 Years Ago by mike_2000_17 [URL="http://en.wikipedia.org/wiki/Static_scoping#Dynamic_scoping"]Wikipedia[/URL] I never heard of dynamic scoping, and to no surprise after reading this wiki. There is no dynamic scoping in C++, and frankly, I'm happy there is none because it seems more hurtful than helpful. new ISO `for' scoping? 18 Years Ago by aPPmaSTer …: [INLINECODE]name lookup of `j' changed for new ISO `for' scoping [/INLINECODE] Here's the part of the code where it… name lookup of â€˜jâ€™ changed for new ISO â€˜forâ€™ scoping 16 Years Ago by BoneXXX …: error: name lookup of ‘j’ changed for new ISO ‘for’ scoping dynn.cpp:370: error: using obsolete binding at ‘j’ [/code… [Error] name lookup of 'n' changed for ISO 'for' scoping [-fpermissive] 11 Years Ago by Jake_4 … solution?

My personal process says "scope everything" - loops, conditionals (if/then/else), etc. IE, place proper brackets around all loops and conditional blocks of code. Then, when you need to add a line to them, they will still be properly constrained! :-) Scoping anonymous functions 15 Years Ago by chamika.deshan Hi I have a loop looping through an "band" object array. I am assigning a anonymous functions for the object property(actually dragging) [CODE]for (var j=0;j<5;j++) { var othis = this.bands[j]; othis.onDragstart = (function() {return othis.onDragstartResizeHandle()}); }[/CODE] onDragstartResizeHandle function [CODE]… Re: Scoping anonymous functions 15 Years Ago by chamika.deshan [QUOTE]othis.onDragstart = (function() {return othis.onDragstartResizeHandle()});[/QUOTE] This is crazy. If i not travelling a loop and access objects one by one like [CODE]var othis1 = this.bands[0]; othis1 .onDragstart = (function() {return othis1 .onDragstartResizeHandle()}); var othis2 = this.bands[1]; othis2 .onDragstart = (function() {… Re: new ISO `for' scoping? 18 Years Ago by iamthwee Declare int j before the for loop. int j; for( j=count;j<prod;j++); { ct[j][0]=50+(j-count+1)*offset; //error here count++; } Re: new ISO `for' scoping? 18 Years Ago by aPPmaSTer Yep, that fixed it. Thanks a bunch! Re: new ISO `for' scoping? 18 Years Ago by Salem > for(int j=count;j<prod;j++); It didn't fix a damn thing, you just moved the problem. The scope of 'j' ends at that ; at the end of the line - this is a loop which does NOTHING then exists. Had you removed this ; then the problem would have fixed itself and the loop would do what you want. As no doubt you're about to comment that now… Re: new ISO `for' scoping? 18 Years Ago by iamthwee Ah never noticed the semicolon there. Re: new ISO `for' scoping? 18 Years Ago by aPPmaSTer Lol, me neither! And you're right, the first solution just let the thing compile, but the program didn't actually work the way it was supposed to. This fixed it for real. Thanks! Re: name lookup of â€˜jâ€™ changed for new ISO â€˜forâ€™ scoping 16 Years Ago by Ancient Dragon At line 17 of the code you posted the variable [b]j[/b] is only visible in that for loop. If you want to use that variable again on line 21 it will have to be declared again just like it was on line 17. Another way to fix the problem is to declare that variable on line 14 similar to the way those other integers were declared, then remove the … Re: name lookup of â€˜jâ€™ changed for new ISO â€˜forâ€™ scoping 16 Years Ago by BoneXXX Thank you very much, problem is fixed. Re: [Error] name lookup of 'n' changed for ISO 'for' scoping [-fpermissive] 11 Years Ago by Labdabeta This is one of those sneaky bugs. Basically it is telling you that if you declare a variable in the for loop, it only lasts as long as the for loop. At first glance it looks like you only ever use 'n' inside your loop. You are wrong.
