using namespace std;

int hailstoneLength(int n) //defining method hailstoneLength

{

int t=1; //defining integer variable assign  

while(n!=1) //define a loop that checks value is not equal to 1

8

Explanation:

Program description can be given as follows:

  • In the given C++ language program an integer method "hailstoneLength", is declared, that accepts an integer variable "n" in its parameter.
  • Inside the method, an integer variable t is declared, that assign a value that is 1, in the next line, a while loop is declared, that uses if block to check even condition if number is even it divide by 2 and increment t variable value by 1.
  • If the number is odd it will multiply the value by 3 and add 1 and increment t by 1 then it will go to if block to check value again. when value of n is not equal to 1 it will return t variable value.
  • In the main method, an integer variable "n" is used that call the method and print its return value.
