Q:selling price is doubled profit is tripled then what is the profit percentage?

 Answer     Let C.P. be Rs. x and S.P. be Rs. y.

Then, 3(y - x) = (2y - x)    y = 2x.

Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x.

Profit % =		x	x 100	% = 100%
		x

Q: main()

{
              int c[ ]={2.8,3.4,4,6.7,5};
              int j,*p=c,*q=c;
              for(j=0;j<5;j++) {
                          printf(" %d ",*c);
                          ++q;     }
              for(j=0;j<5;j++){
printf(" %d ",*p);
++p;      }
}

Answer:
            2 2 2 2 2 2 3 4 6 5
Explanation:
Initially pointer c is assigned to both p and q. In the first loop, since only q is incremented and not c , the value 2 will be printed 5 times. In second loop pitself is incremented. So the values 2 3 4 6 5 will be printed.

main()
{
             int i=65;

Since the #define replaces the string  int by the macro char
