One Function at a Time (Hailstone Sequence)

Question

Good afternoon everyone,

I'm currently working on the following program:

__________________________________________________________
// Tab stops: 4

//The program will use a given integer from the user to compute a
//a particular sequence. Tab tops 4.
#include <iostream>
#include <cstdio>
using namespace std;

//Function Variable Declaration.
int hailstone_Sequence(int n), lengthof_Sequence(int l);

int[] hailstone_List [ ];

//void Print_Set(int [] set, int size);

int main(int argc, char** argv)
{
int user_Input; cin >> user_Input;

cout << "What number shall I start with? " << user_Input << endl;

cout << "The hailstone of sequence starting at " << user_Input << " is: " << hailstone_Sequence(user_Input) << endl;

cout << "The length of the sequence is ___. \n";

cout << "The largest number in the sequence is: \n";

cout << "The longest hailstone sequence with a number up to __ has length ___ ";

cout << "The longest hailstone sequence with a number up to __ begins with ___ ";
return 0;
}

/* The hailstone sequence takes an integer (n) that is greater than 1 from the user. If
// n is even, computes n/2. If n is odd, computes 3n+1. Both are done till integer 1
// is reached.
*/
int hailstone_Sequence (int n)
{
if (n > 1)
{
while (n != 1)
{
if ((n % 2) == 0 )
{
return n / 2;
}
else
{
return (3*n) + 1;
}
}
}

}

// int lengthof_Sequence(int l);
// {
//
//
//
//
//
// }

// void Print_Set(int [] set, int size)
// {
//
//
//
// }

____________________________________________________

The program is to use an integer provided by the user for a Hailstone Sequence, then to list the Sequence out. Example:

user integer: 22

list: #, #, #, #, #,

***Just noticed it cut off the rest of my question***

I have an idea on what I would like done, but not sure how to go about it in cpp. Only have little under a month in this language. I'm looking to take the values from the hailstone_Sequence to be in array for display. Any advice would be much appreciated. Looking to learn as much as I can.

I'll look into taking out the returns from the loop in hailstone_Sequence for starters.

Something like this:

/* The hailstone sequence takes an integer (n) that is greater than 1 from the user. If
// n is even, computes n/2. If n is odd, computes 3n+1. Both are done till integer 1
// is reached.
*/
int hailstone_Sequence (int n)
{
int x = 0;

if (n > 1)
{
while (n != 1)
{
if ((n % 2) == 0 )
{
n = n / 2;
}
else
{
n = (3*n) + 1;
}
x++;//Will be used for the array's length
//Array function here;
}
return n;
}

}
