Copy Array Logic

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 so first element will be printed every time, the value 2 will be printed 5 times. In second loop p itself is incremented and printed. So the values 2 3 4 6 5 will be printed.
