3*4矩阵，求出最大的那个元素的值，以及其所在的行号和列号

#include<stdio.h>int main(){int i = 0;int j = 0;int row = 0;int colum = 0;int max;int a[3][4] = {{1,2,3,4},{9,8,7,6},{-10,10,-5,2}};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\n",max);printf("row=%d\n",row);printf("colum=%d\n",colum);return 0;}
