Passing values to a class

[Donos]

Hello

I have a program as given in following,

class CCmdValue
{
int a, b;
void Put(int x, int y) { a = x; c = y;}
};

class CCmdData
{
CCmdValue pValue;
pValue->Put(10, 20);

CCmdModule pCmd;
pCmd.NewValues(pValue);
};

class CCmdModule
{
friend class CCmdModuleFactory;
CCmdValue mValue;
};

class CCmdModuleFactory
{
CCmdModule& NewValues(CCmdValue& pValue)
{
CCmdModule* p = new CCmdModule;
p->mValue = pValue; // THIS LINE FAILS
}
};

When i try to pass the value of "pValue" to "mValue" It fails. It
doesn't give any compilation error, but when i try to read the integer
values, they don't have any vlaues assigned to them.

Any idea why thats happening?

Thanks in advance.

This class has no public methods, so you can't really do anything with
it other than default construct, copy construct, or assign it.

class CCmdData
{
CCmdValue pValue;
pValue->Put(10, 20);

This should give a compile-time error.

CCmdModule pCmd;
pCmd.NewValues(pValue);
};

class CCmdModule
{
friend class CCmdModuleFactory;
CCmdValue mValue;
};

class CCmdModuleFactory
{
CCmdModule& NewValues(CCmdValue& pValue)
{
CCmdModule* p = new CCmdModule;
p->mValue = pValue; // THIS LINE FAILS
}
};

When i try to pass the value of "pValue" to "mValue" It fails. It
doesn't give any compilation error, but when i try to read the integer
values, they don't have any vlaues assigned to them.

Any idea why thats happening?

How about providing a minimal, compilable, executable sample that
exhibits the behavior in question?

Doing almost anything with these classes as they are shown here will give
compile time errors, since nothing is declared public. Everything is
private to each of the classes. Also, there are syntax errors. CCmdValue
pValue; is an instance. Yet you use it as a pointer, which would produce an
error.

Please show the actual code that is causing the problem.
