Display new line depending on users input of terms per line - c++

Question

This program outputs terms in a Jugglers Series based on user input of first term, number of terms to calculate and terms per line
#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;
//prototype
int ValidateInput (string Prompt);
int main()
{
//local variables
long long int firstTerm;
int termsToCalc;
int termsPerLine;
int count;
//tells user what program does
cout << "Program will determine the terms in a Juggler Series" << endl << endl;
//calls user function to read in the frist term
firstTerm = ValidateInput ("Enter the first term: ");
cout << endl;
//calls user function to read in the number of terms to calculate (after the first)
termsToCalc = ValidateInput ("Enter the number of terms to calculate (after the first): ");
cout << endl;
//calls user function to read in the number of terms to display per line
termsPerLine = ValidateInput ("Enter the terms to display per line: ");
cout << endl;
cout << "First " << termsToCalc << " terms of Juggler series starting with " << firstTerm << endl << endl;
count = 1;
do
{
if ((count % termsPerLine) == 0)
{
cout << "\n";
}
//the term is even take it to the power of 1/2 and increase the count 1
if (firstTerm % 2 == 0 )
{
firstTerm = pow(firstTerm , 0.5);
cout << setw(16) << firstTerm << endl;
count++;
}
//the term is odd take it to the power of 3/2, and increase the count 1
else
{
firstTerm = pow(firstTerm, 1.5);
cout << setw(16) << firstTerm << endl;
count++;
}
}
//continue looping until the terms to calculate is no longer less than or
// equal to the count
while (count <= termsToCalc);
return 0;
}
int ValidateInput (string Prompt)
{
//local variable
int number;
//prompts user for first term, and reads in number
cout << Prompt;
cin >> number;
//user input must be positive, a while loop will check user input and
//continue to check until the term is positive.
while (number <=0)
{
cout << "Error - Enter a positive number" << endl;
cin >> number;
}
//returns number to main function
return number;
}
This is the current printout
This is how I would like it to look
I can not figure out how to edit the output statement to make this display correctly
After removing the endls and moving the new line statement to the end I now get the correct print out but with an extra term

Answer 1

First of all, remove the endls from these:
cout << setw(16) << firstTerm << endl; // -> cout << setw(16) << firstTerm;
And perhaps move this part:
if ((count % termsPerLine) == 0)
{
cout << "\n";
}
to the end of the loop. So it becomes:
count = 0;
do {
if (firstTerm % 2 == 0 ) {
firstTerm = pow(firstTerm , 0.5);
cout << setw(16) << firstTerm;
} else {
firstTerm = pow(firstTerm, 1.5);
cout << setw(16) << firstTerm;
}
if ( (count + 1) % termsPerLine == 0) {
cout << "\n";
}
count++;
} while (count < termsToCalc);
