Look at this wonderful tutorial: Java to C++ Tutorial.
I started in C/C++. Java and C# were much easier to learn because they got plenty of syntactic sugar from C++

Hello everybody,
I want you to help me.
This is the question :
In dynamic polymorphism , if you had a pointer point to base class , it also can point to derived classes.
Example :
class Base {};
class Derived_1 : public Base {};
class Derived_2 : public Base {};
class Derived_3 : public Base {};
int main()
{
Base *BPtr;
int choice;
cout << "Which object do you need(1,2,or 3) ?";
cin >> choice;
switch(choice)
{
case 1: BPtr = new Derived_1(); break;
case 2: BPtr = new Derived_2(); break;
case 3: BPtr = new Derived_3(); break;
default:
cout << "Error number";
} // switch
} // main
*** In the exam above , I used switch...case control , so I want to ask you : by what way , you don't use switch...case in that exam ?????
I want to become a programmer.

The key point in the code was not focused on switch but polymorphism. You should have a look at the downcasts, upcasts, and the usage about dynamic_cast<> in your textbooks.
If you insist to replace the switch in the code, try if - else.

When I am writing a little endian 4 byte int for the integer value 10 it writes out 5 bytes: '0D 0A 00 00', which is an extra byte in the first position.
10 should be '0A 00 00' but no matter how I try to write it out it ends up with 0D (which is the value signed byte 13).
The program creating the file is a C program using the fwrite function:
int Total_Points_Qt;
fwrite(&Total_Points_Qt, 4, 1, File);
The value is in an integer. I have tried unsigned int as well and it does not make a difference.
The extra byte problem does not occur at the values 1-9 and goes away at 11 and does not reoccur again at any other integer value except 10.
Does anyone know why this happens?
Thanks,
Steven

Hi,
My COM Component has a get method that takes pointer to the struct as input.
but when i use interop it is converted to the value not as pointer.
What happens to the pointer parameters during interop.

Hi,
My COM (unmanaged) COmponent has a get method that returns the pointer to
the array of structures.
When using Interop Services ( i.e convertin to managed code by add refernce)
it shows that get method in managed code is simply returning a strucutre and
not a pointer to the array of structures.
How to solve this issue ?
I need the array of structures to be passed - does it needs to do anything
with boxing and unboxing.
Pls help.

you can replace drawing.dll with yours...

I keep getting these errors and I can't figure out why the errors are there.
The line that is throwing these errors is this:
String * pstrDisplay;
BankAccount *pabnkAccounts __gc[];
int pintCurAccount;
pstrDisplay<<pabnkAccounts[pintCurAccount];
I am overloading the << operator like this:
// In class definition
static String *op_LeftShift( String *&, BankAccount * );
// Implementation
static String *op_LeftShift( String *&vstrOut, BankAccount *vbnkAccount )
{
vstrOut = String::Concat("Account Number: ",
vbnkAccount->GetAccountNumber().ToString()),
"\010\013");
return vstrOut;
}
Any help would be great.

Did you put
#include "iostream"
You still need to do this even if you are using MC++
I did this and there was no difference, I got the same error.
cdmlb wrote:
why not use
cout <<pabnkaccounts[pintcuraccount]<<endl;< i="">
I would do this but the BankAccount class is a managed class and I get errors when I try to use ostream in the overload it throws an error saying I can't use unmanaged code in a managed class.
cdmlb wrote:
Console.WriteLine(pabnkAccounts[pintCurAccount].ToString());
I would do something like this, unfortunately it is for school and I have to use the overload method.
I guess that I will have to keep messing around with it. I hope that I won’t have to rewrite the class as unmanaged, but I have to do what I have to do.
Thanks for your help anyway

Well it's weird I write managed and unmanaged code inline all the time. Maybe you could send the file so I can look closer at it.

I could not figure out how to send it to you so I put it online. Here is a link to it:
http://chartermi.net/~reznod/problemcode.zip
The line that is giving me the errors is in 'Part123.cpp' in Part123(), the 3rd case of the switch statement.
I appreciate your help very much.
