Try to solve this, what does the first Printf will show and what does the second will show:

Class A{

Function1(int i){i++}

Function2(int &i){i++}

}

Main{

A Aobj = new A

Int j=0;

Aobj.function1(j)

Printf(%d,j);

Aobj.function2(*j)

Printf(%d,j);

}

Here what is happening is that after the first function it will print 0 because the J was incremented locally and when the function returned the variable was deleted from the stuck, after the second function will print 1 because the address of the variable was sent therefore function2 changed the value on the address where the actual J was excised.
