| 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.
