求3*4矩阵中最大元素及其所在行，列号

#include
int main()
{
	int i, j, row = 0, colum = 0, max;
	int a[3][4]={ {1, 2, 3, 4}, { 9,7,4,6 }, { -1,2,0,8 }};
	max = a[0][0];
	for (i = 0; i <= 2; i++)
	{
		for (j = 0; j <= 3; j++)
		{
			if (a[i][j] > max)
			{
				max = a[i][j]; row = i; colum = j;
			}
		}
	}
	printf("max=%d,row=%d,colum=%d\n", max, row, colum);
	return 0;
}
