Well, and what's your problem? Are you sure that telepathy helps me to get the type_of-gas variable declaration and the calcCharges function signature? It seems you have a very informative diagnostic message.

[code=c++] if (padN > 0) string1.insert(0,padN,' '); [/code] ;)

1. Next time use code tag: [noparse][code=c++] source [/code][/noparse] 2. Alas, you forgot (;)) that case labels are constant expressions of integral (for example, an integer 123 or a single char 'x') or enumeration type. You can't type enumeration constants directly because no overloaded >> operator for enumerations. Input text …

>I'm limited as to what I can give you (security reasons) Hehe, the Top Secret Addendum to the C++ Language ;) It seems nobody can tell you anything with unknown types of state.Variable and saveloadtypes array or strTmp and strBuf scopes or correct pFrame and m_pAppWnd pointer values... There are …

Please, explain these evidently wrong statements: [code=c++] pattern = new char*[size]; pattern = p; ( pattern[i] = new char[length(p, i)] )= p[i]; [/code] See what happens: - You create uninitialized array of pointers to char. - The next statement overwrite a pointer to this array (memory leak) by the parameter …

What's a problem? Class B must be known before A::setErrorMessage definition - that's all. Collect both class definitions in .h file, include it in .cpp file with class A implementation - or simply move up class B definition in your main module just before A::setErrorMessage definition... Apropos, you have posted …

>Which is the most modern (ie c++) way to do this? To do - what? What's a true problem? "Returning a pointer" is not a problem. All snippets in the original post describes different program cases. It seems the right question only helps to correct this bla-bla-bla thread direction ;)...

1. Move all function definitions to a separate .cpp file (and never, ever include them in .h files, except class templates - but it's the other story). 2. Think about [icode]month[i] = !month[i][/icode]

This fseek32 function is an implementation-dependent nonstandard trick: standard C RTL fseek/ftell expects/returns long int (signed 32-bit for VC++) values only. I think it can't move file pointers over 31-bit boundary (you see that). Try to rewrite fseek32 with VC++ non-standard _fseeki64 function with long long (64-bit, old typename __int64) …

Yet another tip: the only correct statement is [icode]return *this;[/icode] ;)

What's a tremendous, innovative C++ syntax! ;) Are you sure that it's DaniWeb members homework?

[QUOTE=xonxon;803981]i am new here,still not familiar with the code.So my Question is i have been given an assignment on how to design a class,pointType , that can store and process a point in the x-y plane.

Don't waste a time with PowerPoint internal formats (especially as PowerPoint is not an analytical MS Office component). Better think about proper export formats: CSV and graphics files (png, gif, jpeg etc). There are lots of ready to use packages to create pictures (with diagrams). It's so easy to import …

[QUOTE=MosaicFuneral;805059]... And I'm sure you'll need more than one string to store a whole page in.[/QUOTE] What's a problem? For example, in VC++ [icode]source.max_size()[/icode] for [icode]std::string source[/icode] is equal to 4294967294 bytes ;)

Regrettably, no need to criticize or edit this code. Yes, it's completely (syntactically and semantically) wrong. It seems the only medicine is to rewrite it from the scratch. Better try to define correct (and useful) class Poly specifications. For example, either the next two strings (or numbers? ) define the …

Some melancholy remarks: The most serious defect of strtok-based CSV parsing is that strtok skips null values. For example, in the line [b]"1st,,3rd,"[/b] strtok selects only two tokens: [b]1st[/b] and [b]3rd[/b]. In practice most of CSV exporters (DBMS especially) write this line for four data fields tuple (record) with null …

You are still mixing declarations and definitions up. Each variable in C++ can have multiple (identical) declarations but should have one and only one definition. This [b]one definition rule[/b] was broken. See [url]http://en.wikipedia.org/wiki/One_Definition_Rule[/url] There are DEFINITIONS of global variables: [code=C++] CAMERA camera; // Allocate static memory for these variables OBJECT …

Look at: [url]http://www.cprogramming.com/tutorial/c/lesson17.html[/url] [url]http://en.wikipedia.org/wiki/Stdarg.h[/url] And never do that, it's a way to nowhere: - No type check (evidently why) for variadic argument lists. - No way to check up the end of argument list in called function

Well, have you ever compile this source? If so, did you ever read compiler diagnostic messages? You declare showSongList as a function with two parameters but you are trying to call it without arguments. Where is a definition of an array of Songs? Why you declare TWO different title entities …

It seems both methods are worst ;) Think about another (more flexible and robust) approach: [code=c] typedef struct sData { /* loaded data description/manipulation */ /* totally dynamics (lists, realloc's etc) */ } Data; /* User interface to the Data storage: */ /** Initialize Data structure to process data */ …

[QUOTE=omdnaik;802588]Hi friends...

How funny! It's [b]htonl[/b] function - H-T-O-N-L ;)

What C compiler are you using? What's this pragma format description in the compiler manuals?

Contrary to your source comments, the class p2dArray has no proper copy constructor(s). You define (wrong) assignment operator but don't define explicit copy constructor. A copy constructor must have (as usually) the signature: [code=c++] p2dArray::p2dArray(const p2dArray&); [/code] No such member declared in your class but default copy contructor (copy member …

Don't forget to clear file state if eof was reached: [code=c++] ... read file until eof // Now f is in fail() and eof(0 state... f.clear(); // Now f is capable to seek... f.seekg(0); ... read again ... [/code]

Use the classic recursive solution approach. Suppose you (your traverse algorithm, of course) are standing at the position (i,j) - level i (from 0 to m-1, up to bottom) column j (from 0 to n-1, left to right). That's a current point of your downward traversal, print it. Now you …

Try this approach: [code=c++] std::string S(double sum) { std::ostringstream s; s << '$' << std::fixed << std::setprecision(2) << sum; return s.str(); } ... cout << "County Sales Tax: " << setw(12) << S(countySalesTax) << endl; ... [/code]

Can you read so fantastically indented program source? Alas, I can't do it :(

Of course, no way to do that in platform-independent manner. Probably the simplest progress bar surrogate for console applications is conio.h based class with feedback call from the (silent) main loop. Try this improvisation: [code=c++] /// Progress indicator console surrogate. /// Place in conticker.h (no dependencies) class ConTicker { public: …

[QUOTE=nucleon;799762]You need to increment the array index to point to the next element for each character read. Here's an example. [code] #include <stdio.h> #define SIZE 1000 int main() { int c, n, i; char a[SIZE]; FILE *file; file = fopen ("filename.txt", "r"); n = 0; while ((c = getc (file)) …

You forgot to add Point() constructor declaration in the class Point definition. Do it.

1. Use [b]code[/b] tags properly: [noparse][code=c] sources... [/code][/noparse] 2. Well, and WHAT's your problem?

1. Initialize an empty tree: [code=c++] TreeNode* root = 0; [/code] You initialize root with new TreeNode which contains garbage (uninitialized) pointers. 2. Discard a strange call of Insert(). No such function in your source. 3. Think about a right place for Insert (root,info) call.

[QUOTE=monkey_king;800004]Hey, does anyone know if it possible to have something like [CODE] #DEFINE NUM_DEC 4 printf("This is your value:%.NUM_DECf\n"); [/CODE] [/QUOTE] Something like?..

Don't waste a time on studies of this incorrect program behaviour. The fatal defect of your class Node manipulations approach is that std::vector is an intrusive container. It has its own copies of all elements. In the function Bi_tree you assign node addresses and manipulate with vector contents at the …
