c++ - 根据用户每行输入的术语显示新行

Question

该程序根据用户输入的第一个术语、要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

这就是我想要的样子

我不知道如何编辑输出语句才能正确显示

删除 endls 并将新行语句移动到末尾后，我现在得到了正确的打印输出，但有一个额外的术语

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";
 }

循环结束。于是就变成了:

 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);
