Q:

What would be the output of the following program?

main()

{

   struct emp

   {

        char *n;

        int age;

   };

   struct emp e1 = { "Dravid", 23};

   struct emp e2 = e1;

   strupr (e2.n);

   printf ("\n%s",e1.n);

}

Answer

DRAVID


When a structure is assigned, passed, or returned, the copying is done monolithically. This means that the copies of any pointer fields will point to the same place as the original. In other words, anything pointed to is not copied. Hence, on changing the name through e2.n it automatically changed e1.n

Q:

Which part of the respiratory system does emphysema damage?

A) Nose B) Lungs
C) Trachea D) Mouth
 
Answer & Explanation Answer: B) Lungs

Explanation:

Emphysema is a condition that involves damage to the walls of the air sacs (alveoli) of the lung i.e, primarily causes shortness of breath due to over-inflation of the alveoli.

 

First, emphysema causes holes to gradually form inside the lungs' air sacs, thereby weakening their internal structure and inhibiting the exchange of oxygen and carbon dioxide.
