由键盘输入一个3×4矩阵a，选出各列最小的元素组成一个一维数组b并输出


这段要怎么写啊,输出结果是什么样的???
哪位帮帮忙啊??

#include "stdio.h"
#include "conio.h"

void main()
{
int i,j,a[3][4],b[4],min;
for(i=0;i<3;i++)
for(j=0;j<4;j++)
scanf("%d",&a[i][j]);
for(i=0;i<4;i++)
b[i]=a[0][i];
for (i=0;i<4;i++)
for(j=1;j<2;j++)
if(a[i][j]<b[i]) b[i]=a[i][j];
for(i=0;i<4;i++)
printf("%d",b[i]);


    getch();
}

using System;
namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            int[ , ] a = new int[3,4];
            int[] b = new int[4];
            for(int i=0;i<3;i++)
                for (int j = 0; j < 4; j++)
                {
                    a[i,j] = Convert.ToInt32(Console.ReadLine());
                    if(j == 3)
                    {
                        Console.WriteLine("");
                    }                  
                }
            for (int i = 0, j = 0; j < 4; j++)
            {
                b[j] = a[i, j];
            }
            for (int i = 0; i < 4; i++)
            {
                for (int j = 0; j < 3; j++)
                {
                    if (b[i] > a[j, i])
                    {
                        b[i] = a[j, i];
                    }                       
                }
                Console.WriteLine(b[i]);
            }         
            Console.ReadLine();
        }
    }
}

这是C的，你发错地方了。

我是想在WINTC里面运行………………

C的也帮你改下吧！好久没做过C了
  for (int i = 0; i < 4; i++)
            {
                for (int j = 0; j < 3; j++)
                {
                    if (b[i] > a[j, i])
                    {
                        b[i] = a[j, i];
                    }                       
                }
             }
把查最小值这儿改下就好了！

哦，谢谢啊
我重新发

using System;
namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            int[ , ] a = new int[3,4];
            int[] b = new int[4];
            for(int i=0;i<3;i++)
                for (int j = 0; j < 4; j++)
                {
                    a[i,j] = Convert.ToInt32(Console.ReadLine());
                    if(j == 3)
                    {
                        Console.WriteLine("");
                    }                  
                }
            for (int i = 0, j = 0; j < 4; j++)
            {
                b[j] = a[i, j];
            }
            for (int i = 0; i < 4; i++)
            {
                for (int j = 0; j < 3; j++)
                {
                    if (b[i] > a[j, i])
                    {
                        b[i] = a[j, i];
                    }                       
                }
                Console.WriteLine(b[i]);
            }         
            Console.ReadLine();
        }
    }
}
