Question

#include <stdio.h>
#include <string.h>

void main()
{
  int smallest, secondsmallest;
  int array[100], size, i;
  printf("\n How many elements do you want to enter: ");
  scanf("%d", &size);
  printf("\nEnter %d elements: ", size);
  for (i = 0 ; i < size; i++)
    scanf("%d", &array[i]);
  if (array[0] < array[1]) {
    smallest = array[0];
    secondsmallest = array[1];
  }
  else {
    smallest = array[1];
    secondsmallest = array[0];
  }
  for (i = 2; i < size; i++) {
    if (array[i] < smallest) {
        secondsmallest = smallest;
        smallest = array[i];
    }
    else if (array[i] < secondsmallest) {
        secondsmallest = array[i];
    }
  }
  printf(" \nSecond smallest element is %d", secondsmallest);
  printf(" \n smallest element is %d", smallest);
}

输入：0 0 1 2

输出：最小值为0，第二小数值为0

我想得到0,1作为输出。我不想在这里使用排序。我怎样才能改进我的代码。

Answer 1

您没有处理重复号码的情况。所以我修改了你的代码。请试试这个并告诉我。

    public void CreateTallPeople()
    {
        var tallPeopleList = new List<IPerson>
        {
            new TallPerson {Height = 210, Name = "Stevo"},
            new TallPerson {Height = 211, Name = "Johno"},
        };
        InteratePeople(tallPeopleList);
    }

    public void InteratePeople(List<IPerson> people)
    {
        foreach (var person in people)
        {
            Console.WriteLine($"{person.Name} is {person.Height}cm tall.  ");
        }
    }

c为阵列中最小和第二小的程序
