I would create a function SetDefault() in SomeObject that sets all the
values to their defaults.

o you cannot do this, since new SomeObject() creates a new object in memory
and returns a pointer to it, and so1 is not a pointer to a SomeObject.
You could do what you want to do by declaring pointers to SomObject as such

SomeObject* pso1;

pso1 = new SomeObject(); // memory is allocated dynamically and is pointed
at by pso1
pso1->setvalue1(1);
pso1->setvalue2(1);

// If you want a new "clean" object, simply delete the one created, and
create a new one
delete pso1; // If this is omitted, you would have garbage = memory not
pointed to by anyone
pso1 = new SomeObject(); // a new object is created in memory and is pointed
at by pso1
