根据用户输入的每行条目显示新行

Question

该程序根据第一学期的用户输入，计算的术语数和每行术语输出Jugglers系列中的术语

#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;

}

这是当前的打印输出

这就是我希望它的样子

我无法弄清楚如何编辑输出语句以正确显示

删除endls并将新行语句移到最后我现在得到正确的打印输出但是有一个额外的术语

Answer 1

首先，从这些中删除endl：

cout << setw(16) << firstTerm << endl; // ->  cout << setw(16) << firstTerm; 

也许移动这部分：

 if ((count % termsPerLine) == 0)
 {
        cout << "\n";
 }

到循环结束。所以它变成了：

 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);
