c语言二维数组求最大值

 #include<stdio.h>
 int main()
 {
     int i,j,row=,colum=,max;
     int a[][]={{,,,},{,,,},{-,,-,}};
     max=a[][];
 for (i=;i<=;i++)
 {
     for (j=;j<=;j++)
     {
         if (a[i][j]>max)
         {
             max=a[i][j];
             row=i;
             colum=j;
         }
     }
 }
 printf("max=%d,row=%d,colum=%d",max,row,colum);
 printf("\n"); }
