从一组数据中找出最小，最大，奇数和偶数之和 [英] Find smallest, largest, number of odd, and sum of even numbers from a group of data

问题描述

我需要找到最小的最大奇数和偶数来自一组数据。

I need to find the smallest largest number of odd and sum of even from a group of data.

数据文件示例

2

1 2 4 5 6 7 8
$
2 5 6 7 4 2 1

2
1 2 4 5 6 7 8
2 5 6 7 4 2 1

第一行给出需要读取的行数（示例中为2）

The first line gives the number of lines that needs to be read (which is 2 in the example)

这就是我的尝试

#include<iostream>
#include<fstream>
#include<string>
#include<iomanip>


using namespace std;

int main()

{

    ifstream infile;
    ofstream outfile;

    infile.open("input.txt");
    outfile.open("output.txt");

    int max = INT_MIN, min = INT_MAX, num_even = 0, num_odd = 0;
    int number, sum_even=0;
    int counter = 0;
    cout << "Test\n\n";
    cout << setw(15)<<left<<"Line";
    cout << setw(15) << left << "Smallest #";
    cout << setw(15) << left << "Largest #";
    cout << setw(15) << left << "# of Odds";
    cout << setw(15) << left << "Sum of evens\n\n";

    for (infile>>counter; counter>=1; counter--)
    {
        while (infile >> number)
        {

            if (number % 2 == 0) {
                num_even++;
                sum_even = sum_even + num_even;
            }

            else
                num_odd++;

            if (number > max)
                max = number;

            if (number < min)
                min = number;
        }
        cout << setw(15) << left << counter;
        cout << setw(15) << left << min;
        cout << setw(15) << left << max ;
        cout << setw(15) << left << num_odd;
        cout << setw(15) << left << sum_even << endl;
    }

    infile.close();
    outfile.close();
    system("pause");
    return 0;
}

它只是将数据作为一个完整的集合而不是逐行读取

摘要

最小[数字]，最大[数字]，奇数[数字]数和来自
数据组的偶数[数字]之和。它运行正常，但我希望它读取第一个数字（2），并知道它有2行数据可供阅读。然后我希望它读取这两行数据并从中找到最小[数字]，最大[数字]，奇数[数字]和偶数[数字]
之和。数据文件中的第一行给出了它应该单独读取的行数  

smallest [number], largest [number], number of odd [numbers] and sum of even [numbers] from a group of data. It runs fine but I want it to read the first number (2) and know that it has 2 lines of data to read. Then I want it to read those 2 lines of data and find the smallest [number], largest [number], number of odd [numbers] and sum of even [numbers] from it. The first line in the data file gives the number of lines it should read seperately 

推荐答案

我还需要不使用向量。只是简单的循环

Also I need to do it without using vectors. Just simple loops
