解答:

#include <iostream>
using namespace std;

#define MONTHSCOUNT 12
#define YEARS 3

int main()
{
	string months[MONTHSCOUNT] = { "January","February","March","April","May","June",
								  "July","August","September","October","November","December" };
	int sales[YEARS][MONTHSCOUNT] = { 0 };
	int sum[3] = { 0 };
	for (int j = 0; j < YEARS; j++)
	{
		for (int i = 0; i < MONTHSCOUNT; i++)
		{
			cout << "请输入第"<<j+1<<"年,第"<< i + 1 << "月的图书销量:";
			cin >> sales[j][i];
			sum[j] += sales[j][i];
		}
	}
	

	for (int j = 0; j < YEARS; j++)
	{
		cout << "第" << j + 1 << "年每月的销量如下:" << endl;
		for (int i = 0; i < MONTHSCOUNT; i++)
		{
			cout << months[i] << "的销量为:" << sales[j][i] << endl;
		}
		cout << "第" << j + 1 << "年的总销量为:"<<sum[j] << endl;
		cout << endl;
	}

	cout << "\n这个三年的总销售量为:" << sum[0] + sum[1] + sum[2] << endl;
	
	return 0;
}

运行结果:

考查点:

• 二维数组
• 嵌套循环
