Q:

At what temperature do the Fahrenheit and celcius scales give the same reading?

A) 212 degrees B) 32 degreees
C) -40 degreees D) 0 degreees
 
Answer & Explanation Answer: C) -40 degreees

Explanation:

We want the temperature when F=C.

We know that, F = C x 95 + 32

So substituting C For F, we have C = -40o

Therefore,  C = -40. 

Thus when C = -40, we have C = F

Q:

How would you check whether the contents of two structure variables are same or not?

Answer

struct emp


{


     char n[20];


      int age;


};


main()


{


    struct emp e1 = {"Dravid", 23};


   struct emp e2;


   scanf ("%s %d",e2.n, & e2.age);


   if( structcmp (e1,e2) ==0)


        printf ("The structures are equal");


   else


         printf ("The structures are unequal");


}


structcmp ( struct emp x, struct emp y)


{


     if (strcmp (x.n,y.n) ==0)


           if (x.age == y.age)


            return (0);


            return (1);


}


In short, if you nee to compare two structures, you'll have to write your own function to do so which carries out the comparison field by field.
