You are required to write a program to implement the EXPRESSION EVALUATION problem above using an appropriate data structure. Your program must include the functionalities to enable the user to evaluate any expression with the following minimum assumptions

Operands may be negative
Operators must include (^, %, *, /, +, -,)
Test for division by zero
Parenthesis Checking
Allow Sin, Cos and Tan values

If i give 2+3(4) in the window, it is giving 5.000 but that is wrong.

if you had read the article in detail, you would have seen that VisualCalc don't support implicit multiplication...

it is written black on white dude !!

when the calc see what you asked it, it tries to resolve a function name...

see the error 0xn301 in the help dialog > Error codes tab.

moreover, this question had a better place directly at the bottom of the article itself, more than the Visual C++ forum (as it relates to) ; i'm sure you would have done so if i didn't author the article too... Wink | ;)

The Code Project forums are not here for you to find someone to do your homework. They are here for you to get help when you have a programming problem that you can't solve on your own.

Try to write the program yourself. Once you have something working, if you still have a problem, feel free to come back and ask.

One hint: If the assignment seems too large or overwhelming, pick one small part of it to get working first. For example, if you are writing an expression evaluation program, write the part that prompts the user for an expression, and then print it back out. Implement only a single operator to start. Initially, leave out the parentheses handling. This is a fundamental principle of software engineering: Break The Problem Down Into Manageable Pieces.

Good luck.

Hi All,
How I could validate and evaluate c based expression like--

(a < b && g > l) || (N == true)

I am new to this forum. If it is already discussed please provide me link.

migrate to different DBMS using ODBC?

Hello!

I am developing a database program using Access DB.. Now im using MFC ODBC classes to connect to Access.. Now at some point, i need to connect to a MS SQL Server DB

Can I do it with little code change or no code change, recompilation at all? Do I just supply a different driver/connection string and thats it!?!?

Im just trying to clarify since ODBC is supposed to do that..

Haven't installed a SQL Server on a PC yet, but i wanna know in advance how ODBC really works...

The only think that you'd have to do is to install the ODBC implementation for SQL Server (usually comes with SQL Server installation), create the new DSN and change the connection string.
Depending on the versions of the DBMS you'd have to take care of the SQL implementation that they use because some statements couldn't be supported: transactions, ... but I don't think you'll have these kind of problems migrating from Access to SQL Server (on the other way probably).

Click on the link below to 'My Articles' and check out my QuickQuery project. I'm using ODBC, and so far, it's worked with every type of database I've had on my system. It may not be exactly what you want (I think it was the first or second program I ever made in C++), but I hope it can help you in some way.

Office XP style menu (non-MFC)

I'm looking for a non-MFC/WTL (ie. just Win32) menu class that implements the Office XP visual style. Everything on CodeProject seems to be MFC/WTL based.

Any suggestions ?

Hi all

I am retrieving Hardware information by using WMI(Windows Management Instrumentation)classes.Here when I access any property of datetime data type then Run time error occurs. I am using VARIANT data type to take the values from WMI classes.

So Please tell me that how should I proceed to print values of datetime data type into the textbox.

Tanks.

The Code snippet is as follows
Here I am using Win32_OperatingSystem Class to access LastBootUpTime property and want to print it in text box, But it gives error.

Although I am able to take other properties of String data type of same class.

So please tell me solution.

IEnumWbemClassObject * pEnumObjectOS = NULL;
HRESULT hResOS;
BSTR strQueryBI = (L"Select * from Win32_OperatingSystem");
BSTR strQLOS = (L"WQL");
hResOS = pWbemServices->ExecQuery(strQLOS, StrQueryOS,WBEM_FLAG_RETURN_IMMEDIATELY,NULL,&pEnumObjectOS);

if(hResOS != S_OK)
{
MessageBox("Could not execute Query");
return;
}

ULONG uCountOS = 1, uReturnedOS;
IWbemClassObject * pClassObjectOS = NULL;

hResOS = pEnumObjectOS->Reset();

if(hResOS != S_OK)
{
MessageBox("Could not Enumerate");
return;
}

hResOS = pEnumObjectOS->Next(WBEM_INFINITE,uCountOS, &pClassObjectOS, &uReturnedOS);

if(hResOS != S_OK)
{
MessageBox("Could not Enumerate");
return;
}

VARIANT vOS;

//CString szStr;

BSTR strClassPropOS = SysAllocString(L"LastBootUpTime");

hResOS = pClassObjectOS->Get(strClassPropOS, 0, &vOS, 0, 0);
if(hResOS != S_OK)
{
MessageBox("Could not Get Value");
return;
}

SysFreeString(strClassPropOS);

_bstr_t bstrPathBIOS = &vOS; //Just to convert BSTR to ANSI
//char* strPath=(char*)bstrPath;

//COleDateTime dateTime(vBIOS.date);
// szStr=dateTime.Format("%H%M%S");

if (SUCCEEDED(hResOS))
SetDlgItemText(IDC_EDIT1,(char*)bstrPathOS);//MessageBox(strPath);
else
MessageBox("Error in getting object");

VariantClear( &vOS );

Thanks.

Am I miss something?? strQueryBI is never executed. You should be doing something like:

<br />
hResOS = pWbemServices->ExecQuery(strQLOS, strQueryBI ,WBEM_FLAG_RETURN_IMMEDIATELY,NULL,&pEnumObjectOS);<br />

Read this[^] if you haven't it may help you.

Hello,

Does:

char* pBuf = new char[nDataSize];
pBuf[nDataSize - 1] = '\0';

help?

If this does not help, could you specify your problem a little bit more clearly? Some code snippets might help also..

Hi I am more specific here:

char* buff = new buff[5];<br />
buff[0] = 'a';<br />
buff[1] = '\0'; // I want this also to be displayed on the next printf()<br />
buff[2] = 'b';<br />
printf(buff); // Should be a b and should not be a only<br />
if(buff)<br />
delete [] buff;

Any solutions?
