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.
