Q:

How do you detect a sequence of "1101" arriving serially from a signal line?

Answer

A SIPO and AND gate circuit can detect this sequence.The output of SIPO is connected to a four input AND gate ,the third SIPO output should be connected through a NOT gate.When the 1101 sequence is loaded in to the SIPO the AND output goes HIGH otherwise keeps LOW.

Q:

A boy sitting in a train moving with a uniform velocity drops a coin outside. A man standing outside the train will find the trajectory of the coin to be

A) a parabola B) a circle
C) a horizontal straight line D) a vertical straight line
 
Answer & Explanation Answer: A) a parabola

Explanation:

Parabola, because when the coin is dropped at a particular point, it has the same velocity as the running train. So by Newton's first law, it continues its motion horizontally with that velocity. But then, it is also pulled down by earth's gravity continuously. In this situation its horizontal motion gives way to the parabolic motion until it reaches the ground.

Q:

How would you use qsort() function to sort an array of structures?

Answer

#include "string.h"


#include "stdlib.h"


struct stud


{


       int rollno;


       int marks;


       char name[30];


};


int sort_m (struct stud *, struct stud *);


int sort_name (struct stud *, struct stud *);


int sort_marks (struct stud *, struct stud *);


 


main()


{


static struct stud ss[] = {


                                            { 15, 96, "Akshay" },


                                            { 2, 97, "Madhuri" },


                                            { 8, 85, "Aishvarya" },


                                            { 10, 80, "Sushmita" }


                                   };


int x,w;


clrscr();


w = sizeof (struct stud);


 


printf ('\nIn order of roll numbers:");


qsort (ss, 4, w, sort_rn);


for(x=0; x<4;x++)


     printf ("\n%d%s%d", ss[x].rollno, ss[x].name,ss[x].marks);


 


printf("\n\nIn order of names:");


qsort(ss, 4, sort_name);


 


for (x=0; x<4;x++)


      printf("\n%d%s%d",ss[x].rollno, ss[x].name,ss[x].marks);


printf("\n\nIn order of marks:");


qsort(ss,4,w,sort_marks);


 


for (x=0;x<4;x++)


      printf ("\n%d%s%d",ss[x].rollno,ss[x].name,ss[x].marks);


}


int sort_rn (struct stud *t1, struct stud *t2)


{


     return (t1->rollno-t2->rollno);


}


 


int sort_name (struct stud *t1, struct stud *t2)


{


     return (strcmp(t1->name,t2->name));


}


int sort_marks (struct stud *t1, struct stud *t2)


{


     return (t2->marks-t1->marks);


}
