Simple C question from a newbie. - Getting ascii value of a keypress. Hi all. I hope there's a few here still? These newsgroups are bleeding away. I'm trying to use online tutorials to teach myself C. (I'm starting with the basics before eventually trying for Objective C.) I have Code::Blocks compiler installed on my XP machine and I'm trying to create a few functions ATM. On... 23 May 2010 13:32
Oh, wow! Alf is blogging! About programming! (previously posted to comp.lang.c++, sorry that I forgot to crosspost here!) Who said that old hounds can't acquire new ticks? Yep, I'm /blogging/. Or at least making a start on that. Whether I'll continue. Well, time will tell. <url: http://alfps.wordpress.com/> :-) Cheers, - Alf ... 7 May 2010 00:13
iterate trough vector of map Hi, i try to iterate trough a 'vector of map'. The vector<map<string,string> > c; is correctly filled with data. cout << c[0]["RDB$RELATION_NAME"] << endl; works fine but: for (vector<map<string,string> >::const_iterator it = c.begin() ; it != c.end(); ++it) { cout << *it["RDB$RELATION_NAME"] << e... 29 Apr 2010 13:30
Overloaded operators, possibly silly question. I'm at the design stage of a package which will perform some operations on data objects of variable size, and converting myself to C++ after years of writing C. I can create a class to represent the objects I'm dealing with. The normal arithmetic operators are meaningful for these objects, so I plan to over... 29 Apr 2010 13:30
redirect std::cout Hi, is it possible to redirect std::cout (or other streams) to a other target? For example to a TMemo-Field (Borland C++Builder 2009) so that std::cout << "hello world" << endl; goes to this memo-field? ... 8 May 2010 13:23
Questions from a newbie How do I become good at programming? What C/C++ books would you recommend? For starters, I'm looking for information on the programming process. I want to know how to plan and design a program. So far, when I write a very small program I just hop on my computer and start typing. I know that's not how it's do... 27 Apr 2010 16:45
Learning try throw catch. I have read some on exception handling but I never really understood it or how to use it. Now I am running into problems using an array. I have tracked my bugs to this line. I want to see what the problem is. Is this correct? if((num > 255) || (num < 0)){ return; } try{ bits[num] = col; <--... 7 Apr 2010 04:34
Outlandish Particle Periodic Table update IX Hi there, Salient features:- Cern list of 900 experimental particle results in MeV, double precision and mathematical (Fortran 77) The list alone is not available anywhere-else, as a single list. Not definitive. 42 year scientific project, by ex-Mensa member. (They stopped concessionary subscriptions) 10 year a... 30 Mar 2010 13:50

Scope error I am working my way through 'Accelerated C++" and have come upon a compiler error. The code is cut'n'pasted from downloaded source from the Accelerated C++ website. The compiler gives this error "error:'max' not declared in this scope" (see <<< ERROR below). The program is contained in Section 4.5, pp70-71. As I... 26 Mar 2010 17:51 |
