 | Re: radix sort I would use modulo and div that is if I want to extract the second digit of 234 I would (234 %100)/10 The first paranthesis, strips out the 2 such that 34 remains this slash 10 then calulates how many timis 10 divides 34 without remainder. |

| | I wouldnt bother with the exponent. I would only use the coefficient and let the position in an "Array" be the exponent. Exponents are by definition integers >0 , so it should be ideally suited for a simple array. the polynomial [TEX]a Z^4 -b Z^3+cZ+7[/TEX] the last term has an … |
 | Hi i am the original poster from the other thread referenced to you. It's very difficult to get decent information, I have actually been reading a oldstyle book, to understand this. If you just want it to work do as stuxyz told me. On a deeper level, I think partial …  |
| | I'm having troubles linking together different classes that uses the same templated class. I found 2 workarounds, that will make it compile, but it's not really a solution. 1. don't do a staged compiling with linking object code 2. inlining the spezialized member functions. I'm looking for a solution that … |
| | [QUOTE=William Hemsworth;818427] If you can't do something like this, try using [URL="http://www.cplusplus.com/reference/clibrary/cstring/strtok.html"]strtok[/URL], it will help you split up the word using a delimiter. Hope this helps.[/QUOTE] Yes a tokenizer is highly recommended. You will end up using it in half you projects. |
| | you should try compiling each of the files into object code, something like g++ -c yourfile.cpp This should check if your compiler is workings, not the crosscompilation linker and all that stuff. To salem. you can compile headers, these are called .pch og h.gch stdafx on visual studio is an …  |
| | Without having looked to much on your code, I would simply shadow the "numberofpayments" variabel in a greater scope, and print out the outputline after the main while loop  |
| | So it's a minimum spanning tree right? if so use either kruskall or prim [url]http://www.boost.org/doc/libs/1_38_0/libs/graph/doc/index.html[/url] But don't bother with the implementation just use boost. |

| | I've made a program using gcc as a compiler. In my loops I've been using a uint type as the type of my loop variable. But now it seems that some systems doesn't support this type. Can I make a preprocessor conditional that does a #define uint to unsigned int …  |
| | I wan't use the multimap on my own templated class. The following is a working example with a builtin type. [CODE=c++] int dat[5] = {0,6,3,7,3}; typedef std::multimap< int, int > asso; asso dict; for (int i=0;i<5;i++){ dict.insert(make_pair(dat[i],i)); } asso::iterator pos; for(pos=dict.begin(); pos!=dict.end() ;pos++) cout << pos->first <<" next "<< pos->second … |
