大家帮我看看这道题

#define M 3
#define N 4
main()
{int max,i,j,r,c;
int a[M][N]={{123,94,-10,218},{3,9,10,-83},{45,16,44,-99}};
max=a[0][0];
for(i=0;i<M;i++)
for(j=0;j<M;j++)
if(a[i][j]>max)
{max=a[i][j]; r=i;c=j;}
printf("max=%d,row=%d,colum=%d\n",max,r,c);
}
运行程序，记录程序的输出，若将a[0][0]改为1230，程序运行结果有错，应如何修改程序？

#include <stdio.h>
#define M 3
#define N 4
int main()
{
int max,i,j,r=0,c=0;
int a[M][N]={{1230,94,-10,218},{3,9,10,-83},{45,16,44,-99}};
max=a[0][0];
for(i=0;i<M;i++)
{
for(j=0;j<M;j++)
{
if(a[i][j]>max)
{
max=a[i][j];
r=i;
c=j;
}
}
}
printf("max=%d,row=%d,colum=%d\n",max,r,c);
return 0;
}

刚才输错了，是j<N
