Classes in if statements

[smmcc]

I want to declare a class if a certain condition is true so i have placed teh constructor in an if statement which in turn is inside a while loop. However i cannot access the class outside the if statement. Is there anyway around this. This is what the code looks like -

void function()

{
While (reason)
{
if (something == true)
{
class newclass;
//Break out of the loop;
break;
}
}//end while
newclass.function1();


Any help would be appreciated/

You could do something like this...

void function( void )
{
    MyClass * lpClass = NULL;

    while( 1 )
    {
        if( something == true )
        {
            lpClasss = new MyClass;
            break;
        }
    }
       
    if( lpClass != NULL )
    {

        lpClass->someMethod();
  
    }

    // Clean Up
    delete lpClass;

    return;

}

no, you should use polymorphism.

In this case how could polymorphism be used?

Based off of the information originally given?

I guess it would also make sense to do this...

while( something == true )
{

   if( somethingelse == true )
   {
         MyClass class;

         class.someMethod();

         break;
   }

}

well if you look at the original case I'd do

While (reason)
if (something)
{
function1();
reason=0;
}
(which is quite usless) but I thought polymorphism was what he asked for
