Iterative solutions with C++
I have an assignment to fill in the body of the following function(detectHappy) that will check whether a number is a happy number or not, for 10 cycles
(iterations) only. I have to:
-Find the sum of the digits of the number.
-Check the result obtained in point 1. If it is 1, assign value 1 to the variable 'finalNumber', else again execute point 1, till the number obtained is 1 or till the number of cycle increases to 10.
-Assign the iteration value to the variable 'cycle_no'.
I am not supposed to input, output or declare any additional functions. I just have to write the body of the function already declared there that will make it work on the shell offered in my course...
The programme I have attempted to write compiles but does not give the correct results. I am now short of ideas and I will be grateful for any assistance. Thank you in advance.
code:
/*Question : Write your code to find whether the number is a happy
number or not (for max 10 cycles).
int number : The number to be determined whether it is happy or not
int finalNumber : Store the resultant value in this variable
int cycle_no : Store the number of iterations done to determine whether
the 'number' is happy or not */
void detectHappy(int number, int &finalNumber, int &cycle_no) {
//Write your solution code below this line
int sum = 0;
int i = 0;
do{
sum += (number%10)*(number%10);
number /=10;
if (sum == 1){
finalNumber = 1;
break;
}
else {
number = sum;
i++;
}
cycle_no = i;
}
while (i < 10);
}
Get rid of the do while loop and add a for loop
int i;
for (i=0; i <10; i++)
{
`Code stuff`
}
