| You are given a string which contains some special
characters. You also have set of special characters. You are
given other string (call it as pattern string). Your job is
to write a program to replace each special characters in
given string by pattern string. You are not allowed to
create new resulting string. You need to allocate some new
memory to given existing string but constraint is you can
only allocate memory one time. Allocate memory exactly what
you need not more not less. | Microsoft | 2 |

| number 2 plssssss help !!....using array.. turbo c..
create a program that will accept a number and determine if
it is a happy number or an unhappy number..
example:
enter a number : 7
7*7=49
then 4 and 9
4*4 and 9*9== 16 + 18 gives you 97
then 9 and 7
9*9 and 7*7 == 81 + 49 gives you 130
then 1 and 3
1*1 and 3*3 == 1 + 9 gives you 10
1*1 gives you 1
sample output:
7= 49= 16+81= 97= 81+49=130 =1+9=10 =1
"7 is a happy number"
. if the last number is 2 then the number being inputed is
not a happy number.
