Given: x == 2 or F(2) I'll rewrite it as (F(1) + F(-1)) which I'll rewrite as ((F(0) + F(-2)) + 3) which I'll rewrite as ((3 + 3) + 3) which is 9 Given x == 3 or F(3) OR (F(1) + F(0)) OR ((F(0) + F(-2)) + 3) …

Welcome to DaniWeb. You should be aware that doing homework for someone else is discouraged, though occasssionally someone gets lucky. Based on the stated requirements you have a wide array of options. Since I don't know what you know it's hard to say what might work best for you. Arrays …

First, you appear to be trying to accomplish this task as though a list is an array, but they aren't the same thing. Swapping (multiple) nodes in a list is very inefficient. Don't do it, even if you could figure out how. To insert a new node at any desired …

1) void binaryAddint* result, int&cBit, const int* bin1, const int* bin2 ); You are missing a ( in there somewhere, probably between Add and int. 2) define carry to be an int, not an int array, and initialize it to zero 3) You are defining binaryAdd() within main() rather than …

why do you need a multimap and not a vector of strings? I doubt you're going to save any time by using a map. It's also not evident why you need the line number to do this, either. An STL string is nothing more than a glorified C style string. …

You need to list header file names, not just the preprossor command include. You may need to include a statement regarding namespace std depending on your compiler. main() should always have return type int, not void. I've never tried to output a string literal equal to this: "&". If that's …

I have no idea what language the original is, but here's a guess as to what it might mean in C++ pseudocode:[code] Declare a function called IsTextFile that takes a single argument of type string called FileName and returns type bool. In the body of the function do the following: …

>>PLEASE HELP!!!! Post code using code tags, include a description of the problem you're having, etc.

Since title, price and publisher are declared with private access within the class the << operator will need to use public accessor methods to do it's job unless it is declared as a friend function within the class.

1) To use std::strings in your program use this line: #include<string> not this: #include<string.h> The latter is a deprecated file for functions to manipulate C style strings. 2) if arrayToClear has capacity of lengthOfArray then the largest valid index for an element of arrayToClear is at lengthOfArray - 1. That …

The terminology used in programming is something that still baffles me at times. What exactly a C++ interface is is one of those terms. On the one hand, C++ interface cam mean how the program presents itself to the user, not with whether the program is started from the command …

Only if the file is highly structured. seekg and seekp will position the file pointer at a specified number of bytes from the beginning of the file, but unless each line has exactly the same number of bytes, trying to place the pointer at the start of the desired line …

strings can hold space char and other whitespace char as well, once you know the details of how stream methods and overloaded operators work. Short story, use getline(), there are two versions, one for C style strings and one for stl string objects.

Try this: ifstream input("infile.txt") while(input.getline(file,100)) { outputfile<<file<<endl; } ios::in is the default for ifstreams so it's not needed. I can't say for sure but I bet the inflie.good() suffers from the same problem as !infile.eof() snippet that many peolp try, given it has the same outcome.

You are missing a & in the definition. The return type in the declaration is const BSTree<T>& but in the definition its const BSTree<T>

>> Do you ever find a good occasion to use eof () Do you ever use it as part of a validation sequence? Specifically, if you read the file with this: while(fin >> sample) how do you know why the loop terminates? That is did the loop terminate because the …

Did you write the file? Can you get the desired char to appear in you C++ program? If you can get the desired char to appear in you program try outputting the char to the screen but cast it to an int in the process and see what the value …

6, 5, 11, 10, 4, 8, 9 each number in that sequence is 3 more than each number in the following sequence 3, 2, 8, 7, 1, 5, 6 which means you increased the value of each element in num[] by 3 not the index used to access the values …

>>getline(infile, ordered, mPrice, sPrice); To my knowledge there is no version of getline() that takes four parameters, and no version of getline() that stores information in ints or doubles. To my knowledge getline() is only for strings . Therefore I'd suggest a series of three calls to >> to obtain …

multiset::multiset( ); The above is a default constructor. It should initialize any member variables to a default value, if they need one. Vectors don't need to be set to a default value and they are the only member variables I see, so none are needed that I can see. Therefore …

remove the single quotes from around the digits in the case statements. What you have are chars not ints. x is an int so use ints. case 1: not case '1':

Line 56 is a function prototype, not a function call and needs to be fixed. On line 19 library is declared to be an array of type pointer to type book. Therefore each library[m] will be a pointer to a book object. Hence to access the members of the book …

1) Add a line like: const int MAXIMUM = 100; at the start of main(). 2) Remove MAXIMUM from the prototype for findMe 3) Be sure the number of parameters for findMe() are the same in the declaration and the function call---as posted they aren't. 4) You don't check for …

Look at the last function you wrote before compiling for the last time. Assuming there were no errors before writing that function then the errors should be somewhere therein. If you didn't compile until after you wrote all of that, then shame on you. You can work it out yourself …

There are two basic errors in the following snippet:[code] else titles[i] = ' '; artists[i] = ' ';[/code] First, lines two and three are supposed to be done every time the else is invoked, but only if the else is invoked. With the code as it stands that won't happen …

look up the various versions of getline(). There's one for C style strings and another for STL string objects.

1) "where can I add the ip and the uri?" I'm not sure exactly you mean by that question. It is possible, but ungainly, to have the user enter (add) all the data needed as input for the program from the command line. It is more common for the program …

You are adding empty strings to the back of the file, not overwriting the desired values by assigning empty strings at the desired index within the vector. For what it's worth I'd suggest using the erase() method of the vector class to remove the entries completely.

If I'm not mistaken the default behaviour of ofstreams or ios::out mode of fstreams is to overwrite the existing file.

Here's an example based on your code that may help:[code] void sortData(int lId[], int fId[], int noOfRows); int main () { int lId[4]; int fId[4]; while (inFile >> fId[i]) { inFile >> lId[i] ; i++; } sortData(lId, fId, i); for (i = 0; i < 4; i++) { outFile << …

It looks like you are trying to use the << operator to print out something that doesn't have the << operator overloaded for it within the printHashMap() function.

A quick problem I see is this: if (function == "fifo" || "lru" || "opt" || "clo") It should be this: [code] if (function == "fifo" || function == "lru" || function == "opt" || function == "clo") [/code]

Welcome to Daniweb! When posting code to this board please enclose int in code tags. You can read about code takes by reading the watermarks that appear in the message box where you enter the information that you want to appear in the post or by reading the anouncement section …

>>Do I need to keep the current functions and add functions such as Only if you want to or need to. But, since you declare and define a non-default constructor you should write a copy constructor, and it would be a good idea to write a default constructor as well. …

The most important thing about using files is you need to know exactly how they are set up. In this case, presumably the title, artist and song are delimited by something other than space so spaces can appear in the name of each field. Maybe the delimiter is a ~ …

1) You have to decide what you mean by making a copy. Since you have pointers within the node objects making up the list/deque if you do a shallow copy then each copy is using the same memory and if one copy is destroyed then the memory for all copies …

The spin could readily be represented by a loop that advances a pointer starting at a given location certain number of times. I'm less certain how you will determine how many nodes there are to be in the wheel.

Please use code tags when posting code to this board. You can read how to use them in the watermarks of the message box or in the anouncemts at the top of the board. main() has return type int. You haven't given it any return type at all. I hope …

On line 6 movem is declared as a two dimensional array of type char meaning each movem[a] is a string and each movem[a][b] is a char. strcpy requires two char *s, or strings if you prefer, so passing movem[i] as in line 9 is correct but passing movem[1][i], a char, …

SavingAccount account1(2100); That is a constructor using an int. Unfortunately, you don't declare such a constructor, so the compiler is complaining. Unfortunately, the compiler thinks you are trying to use the copy constructor, so it's giving you a funny reason for complaining.

I suspect there's a reason why readmatrix has a return type of float*. I'd consider using the return type back in main() by declaring a float * in main() that can accept the pointer value returned and can then pass it to printmatrix(). For thouroughness sake I'd also delete the …

I usually try to write things down on paper before trying to write code. In this case I would probably start with something like this:[code] Goal: Create an unbalanced binary tree starting at root If br value less than root value add br to left child else add br to …

Looping just means do the same thing one or more times. So if you can write code to determine if a given char has a given value, then you use that in a loop using a counter to determine how many of a given char there are in a given …

Variables can be passed by value, in which case a copy of the value of the number is passed, not the number itself; or it can be passed by reference, in which case the number itself is passed. If passed by value then the value of the original variable in …

Welcome to DaniWeb. Please learn to use code tags when posting code to this site. See the watermark in the posting window or the announcement section at the top of the board to learn how. First I think you need to determine whether the char need be case sensitive or …

For the list problem--- 1) the compiler/linker need to have seen at least the prototype, if not the whole definition, of a function before it is called. Since the compiler/linker start at the top and work down, that means the prototype, if not the whole definition needs to occur before …

There are several ways to do it, but you may have to redo some members of the Polynomial class. Here's one possible way to approach it. If the coeffiecent vector contains zero at appropriate element at the power of the variable, then just extend the coefficient vector by adding the …
