3. write a program for reversing the given string.
4. the integers from 1 to n are stored in an array in a random
fashion. but one integer is missing. write a program
to find the
missing integer.
ans. idea. the sum of n
natural numbers is = n(n+1)/2.

missing number.
5. some bit type of questions has been given on pointers asking
to
to find whether it is correct from syntax point
of view. and if
it is correct explain what it will do.(around 15
bits).
