最近在自学C++，做到个题目，要求要有二维数组，要有char*，求三年的销售情况，和总的销售量。是按着需求在写但是却也写的奇怪。
#include<iostream>
#include<vector>
using namespace std;
const int m = 4;
const int n = 12;
int main()
{
vector<vector<int> >num(m, vector<int>(n));//定义二维数组为4*12；
const char* month[n] =
{
"junuary","february","march","april","may","june","july","august","september","october","novenber","december"
};
cout << "请输入第一年各个月的销量：\n";
int i = 0;
while (i < 12)
{
cin >> num[1][i];
//cout<<num[1][i]<<" ";
i++;
}
cout << endl;
cout << "请输入第二年各个月的销量：\n";
int j = 0;
while (j < 12)
{
cin >> num[2][j];
//cout<<num[2][j]<<" ";
j++;
}
cout << endl;
cout << "请输入第三年各个月的销量：\n";
int k = 0;
while (k < 12)
{
cin >> num[3][k];
//cout<<num[3][k]<<" ";
k++;
}
cout << "这三年的销售情况如下：\n\n";
for (int l = 0; l < 12; l++)
{
cout << month[l] << " ";
}
cout << endl;
for (int x = 0; x < 12; x++)
{
cout << num[1][x] << " ";
}
cout << endl;
for (int x = 0; x < 12; x++)
{
cout << num[2][x] << " ";
}
cout << endl;
for (int x = 0; x < 12; x++)
{
cout << num[2][x] << " ";
}
int sum = 0;
for (int k = 0; k < n; k++)
{
sum += num[1][k] + num[2][k] + num[3][k];
}
cout << "这十二个月的总销售量为：" << sum;
return 0;
cout << endl;
return 0;
}
