Six knights - P,Q,R,S,T and U - assemble for a long journey in two travelling parties. For security, each travelling party consists of at least two knights. The two parties travel by separate routes, northern and southern. After one month, the routes of the northern and southern groups converge for a brief time and at that point he knights can, if they wish, rearrange their travelling parties before continuing, again in two parties along separate northern and southern routes. Throughout the entire trip, the composition of travelling parties must be in accord with the following conditions

P and R are deadly enemies and, although they may meet briefly, can never travel together.
p must travel in the same party with s
Q cann't travel by the southern route
U cann't change routes

16) If one of the two parties of knights consists of P and U and two other knights and travels by the southern route, the other members of this party besides P and U must be.
a) Q and S
b) Q and T
c) R and S
d) R and T
e) S and T
Ans: e

Ans: b

1Cool If one of the two parties of knights consists of U and two other knights and travels by the northern route, the other memnbers of this party besides U must be

printf("%d %d %d",i++,i++,i--);
there is one or two more question on increment operator

2) Two question on redirection operator(>>)

3) int i=10;
if(1,i++,++i)
printf ("The value for i is %d",i);

4) one question on structure and u have to fine the error in the syntax

5) int a=10,b=33;
a=a^b;
b=a^b;
a=a^b;
printf("%d %d", a,b);

6) int *a;
int (*b)();
printf("%d %d",sizeof(a),sizeof(b);

7) # define SQR(a) (a*a)
void main()
{
printf("%d", SQR(5));
}
Cool And in another question # define directive is declared in the main() function of the program and u have to predict the output of the program.?

9) what is the time complexity of bubble sort (Ans: O(n^2))
