输入一个3×6的二维整型数组，输出其中最大值、最小值及其所在的行列下标。

#include <iostream>
using namespace std;

int main()
{
int a[3][6];
int max,min,maxX,maxY,minX,minY;
maxX = maxY = minX = minY = 0;
for (int i = 0;i < 3;i++)
for (int j = 0;j < 6;j++)
cin >> a[i][j];
max = min = a[0][0];

for (int i = 0;i < 3;i++)
for (int j = 0;j < 6;j++)
{
if (a[i][j] > max)
{
max = a[i][j];
maxX = i;
maxY = j;
}
if (a[i][j] < min)
{
min = a[i][j];
minX = i;
minY = j;
}
}
cout << "最大数为:" << max << " 下标为(" << maxX << "," << maxY << ")\n";
cout << "最小数为:" << min << " 下标为(" << minX << "," << minY << ")\n";
return 0;
}
