| | I'm not real sure what your question is. Are you trying to separate the names as you input them? Separating them is the easy part. The hard part is managing the data after the input. I think you could do something with nested loops and a vector of strings. Keeping … |
| | That is what the issue is. Multiple #includes on standard headers aren't a problem, its the the multiple #includes on the custom "vehicle" headers that is the problem. The OP either needs to add header guards or change their inclusion structure to eliminate the redundancies. |
| | Inheritance could also be referred to as "specialization" or an "x [B]is a[/B] y" relationship. For example, a Cat is a "specialized" type of Mammal: What are some things that define a Mammal? Two common ones are "isHairy" and "isWarmBlooded", among others. What are some things that define a Cat? … |
| | You might need to use a dynamic allocation which would then require delete[]. I don't think the compiler will let you do that the way you have because I don't think [iCODE]strlen(msg)[/iCODE] is technically considered a constant. It looks like you want to copy the message before sending it to …  |
| | What is the "something weird"? What you have posted won't compile because you didn't provide the "logic.h" header file... I suspect it's something like: n a m e 1 0 a v g e g r e y n n a m e 2 0 d h i n f …  |
| | Based on what I see, you won't want a const. Are you familiar with the terms "arguments" and "parameters"? |
 | Re: void functions Where and how you initialize them depends on the structure of the program. How much of that structure did the prof give you, and what changes did you make? It may be easiest if you post the given structure as a reference. That would allow us to see your changes … |
| | Re: VC++ question [QUOTE=jwenting;1188053]Those are pretty clear compiler errors. I'd suggest you try to resolve them, and ask specific questions about them if you can't figure out how to go about that.[/QUOTE] I agree.... @OP: [URL="http://www.gidnetwork.com/b-38.html"]I suggest you re-evaluate your formatting and work on readability.[/URL] It appears that you are not matching up … |
 | Considering your filenames, you are probably compiling as C instead of C++. C does not support classes, only C++ does. You will need to change your source filenames from (*.c) to (*.cpp). Also, try changing your class name and file name to something else such as "myStack" or "manualStack". Once … |

| | I'm not familiar enough with .NET to know the exact operator(s) you need, but as I understand things, "String^ line" is a pointer to a string, it is not an actual string. Try to de-reference the pointer when you do your comparison. That's just my 2-cents. Take it how you … |

| | Re: Help needed!!! I'm guessing you're talking about the while on line 29? As you have written it, you are attempting to compare the values stored in the variables named [I]response[/I] and [I]no[/I]. The problem is that the variable [I]no[/I] does not exist. Based on what I see, you should consider re-writing the … |

| | Where do you get tamount from the user? All I see is a declaration without any sort of input or initialization before you write it to the file. This causes the variable to have a really weird value in it (a.k.a. "garbage"). In your browser, do a find with "tamount" … |

| | Since moveNumber is a reference parameter, you should just be able to simply add a line to main(), immediately after the call to move(), that outputs moveNumber just like any other output sequence. |
| | Try changing line 35 to [iCODE]if ($flag == 1)[/iCODE]. You might need to change line 44 to some sort of elseif as well. |
| | It sounds to me like you need header guards in place as well. That way, if a specific header somehow gets #included more than once, the various instances of it aren't butting heads and you only get one set of definitions.

| | Re: strlen I know this is a bit of a "me too" post, but I thought I should clarify daviddoria's response. strlen() only works with C-style strings (null-terminated arrays of [B]char[/B]s). Since you are working with C++ std::strings you can not use it as you have. You need to use the member … |

I don't know it looks fine to me...[/QUOTE] Other than the fact you can't do this? [CODE]cout << ((turn_it_is%2)==1)?(play1:play2) << cout << " it's your turn ";[/CODE] Or that the variable name … |
| | Create another series of loops similar to your input loops. Just convert them to output and perform the necessary arithmetic operations inside them. |
| | The way you wrote it is ambiguous. It could be a recursive reference to itself (which is technically undefined) or a call to one of the compiler's included pre-defined versions of the operator. Either way, I suspect that it does not match your intent. I'm not sure if it will … |

| | [B]delete[/B] is the keyword for dynamic [B]de-[/B]allocation of memory. I see no [B]new[/B] creating a dynamic allocation, so it is not needed. It is used with pointers, and I don't even see any pointers. |
