程序代码：

int min_value(int array[][4],int n)
{
    int i,j,min;
    min=array[0][0];
    for(i=0;i<n;i++)
    {for(j=0;j<n;j++)
            if(array[i][j]<min)
                min=array[i][j];}
    return(min);

}
#include "stdio.h"
main()
{
    int a[2][4]={{101,34,63,28},{90,17,56,62}};
    printf("min value is %d\n",min_value(a,2));

}int min_value(int array[][4],int n)
{
    int i,j,min;
    min=array[0][0];
    for(i=0;i<n;i++)
     for(j=0;j<n;j++)
            if(array[i][j]<min)
                min=array[i][j];
    return(min);

}

{
    int a[2][4]={{101,34,63,28},{90,17,56,62}};
    printf("min value is %d\n",min_value(a,2));
