 | >He can write a kernel, but programming a Graphical Interface is too difficult ... Two completely different things. Though the way the question is worded makes me think of a l33t h4x0r script kiddie with no clue at all about how complex an operating system is. |
| | >void main() int main() >if((StringPtr = new char[26]) == NULL) This may or may not correctly handle errors depending on how old your compiler is. >*(StringPtr+i) = String[i]; You know, you can do [INLINECODE]StringPtr[i] = String[i];[/INLINECODE] too. It's a lot easier to read and write. >cout << "StringPtr = " … |
| | >What does that mean?? erase modifies the string, but your string is const. Well, that's not what the error means, but it's the root cause. ;)  |
| | The translation of your error is that std::map doesn't support random access iterators, and random access iterators are required for std::sort to work. However, std::map is already sorted on the key, so there's no need to explicitly sort anyway. |
| | >What are and how do I use vectors ? Vectors and arrays are conceptually analogous. Due to operator overloading, you can use a vector in much the same way you use an array, with the added convenience of built-in functionality like automatic growth and useful information rolled up into a … |
| | Re: structures >how do i typedef a structure The method I usually see is a compact one: [code=c] typedef struct foo { /* ... */ } foo; [/code] But you can do it your way as well (though note you have a spelling error in the typedef; it's MyStructure, not MyStucture ;)). … |
 | Hmm, this spring doesn't seem very interesting anime-wise. The only one I'm truly looking forward to is Corda d'Oro, but that appears to be more of an epilogue than the second season that fans really want. >Dragonball Kai Dragonball Z without all of the time-wasters? Who wants to bet that … |

| | >Could anybody tell me what happen? You don't know how to properly declare an array in C++: [code=cplusplus] int main() { int maze_size=5; int oppo_pos[3][2] = { {maze_size-1,maze_size-1}, {maze_size-1,0}, {0,maze_size-1} }; return 0; } [/code]  |
| | >It's really freaking complicated Well, duh! ;) It's not as complicated as some people (who haven't learned it and base their opinions on anecdotes) would have you believe, but programming is hard, and assembly is programming without any sugar coating[1]. >so do any of you know of any good tutorials … |

| | Re: Error >Try converting the value using static_cast<int>(yourvalue) ... Casting is the worst possible reaction to an error like this. Putting a dirty plate in a stack of clean plates doesn't make it clean. |

| | [url]http://www.daniweb.com/forums/thread184342.html[/url] It seems AD is seeing something similar to me, but that thread is horribly messed up. I'm viewing it with Firefox 3.0.8 and words can't really describe the jumble of images and formatting that's all wrong.  |
| | >It seems he's declared... a pointer that is also a function? Nope, it's a function that returns a pointer. The closest thing to a pointer that's also a function would be a pointer to a function: [code=c] void (*fp) ( void ); [/code]  |
| | >so who should I believe? which team should i join? You should get all of the facts and form your own unbiased opinion. Mindlessly following one group or another is silly. |

| | > tree_node* root; //???Is this creating pointer root to first node???? Yes, it's the root of the whole tree. >root = NULL; //???start with empty binary search tree???? Correct, though an empty tree doesn't have to be just a null pointer. Often[1], you'll see trees with a dummy root for … |
| | Let's start by clearing up an obvious misunderstanding about pointers. >char *str; >fscanf(inp, "%s", str); This is broken. An uninitialized pointer does not mean a pointer to unlimited space. It means you're not allowed to dereference that pointer or compare it to anything until you initialize it. You still need …  |

| | Re: Snowball Earth I think it's rather arrogant to believe that global warming is mostly our fault (or that we can "fix" it) when there's evidence of several extreme planet-wide climate changes in both directions long before humans were around.

| | I've neither written nor worked with such software, but I imagine it works something like a spam blocker by looking for fuzzy patterns or by comparing patterns from trusted code.

| | >I don’t know how to add + operator. Liar. Aside from not terminating the DistSign class (which I assume is simply a copy/paste error), your overloaded operator works just peachy. It can't be used as an rvalue because it returns void, but that's a design decision, not an "I don't …  |

 | >How do we determine the value of n? If you can't use dynamic memory (and I'm assuming any alternative that uses dynamic memory, like std::vector), your only option is to make the array large enough to handle any reasonable number of records: [code=cplusplus] int P[1000], T[1000], V[1000]; [/code] Of course, … |

| | Since this is extremely likely to be yet another attempt at starting a new thread with the same question, I know exactly what it is you want. But I'm still going to make you explain your question. |
| | You're not handling the default cause of a non-code. Since the first letter is 'm', and there's no substitution for 'm', your output is correct. |
