一维数组转为二维数组

#include<iostream>
using namespace std;


int main()

{

	int a[12];

	int b[3][4], i, j, n = 0;

	int max, mi, mj;

	for (i = 0; i < 12; i++)

		cin >> a[i];

	for (i = 0; i < 3; i++)

	{

		for (j = 0; j < 4; j++)

		{

			b[i][j] = a[n++];

			cout << b[i][j] << " ";

		}

		cout << endl;

	}

	max = b[0][0], mi = 0, mj = 0;

	for (i = 0; i < 3; i++)

	{

		for (j = 0; j < 4; j++)

		{

			if (max <= b[i][j])

				mj = j;

	}

	cout << endl;

	cout << max << " " << mi << " " << mj << endl;
