vector题目
读一组整数到vector对象,计算并输出每对相邻元素的和.如果读入元素个数为奇数,则提示用户最后一个元素没有求和,并输出其值.然后修改程序:头尾元素两两配对,计算每对元素的和,并输出!

求解答啊...搞不懂...用数组会做,但是不懂得vector...

C/C++ code

#include<iostream>#include<vector>using namespace std;void main(){    int n,m;    cout<<"整数个数：";    cin>>n;    vector<int> inter;    for (int i = 0; i != n; i++)    {        cin>>m;        inter.push_back(m);    }    /*    if (0 != n%2)    {        cout<<"最后一个元素没有求和!"<<endl;    }*/    for (vector<int>::size_type index = 0; index < inter.size();)    {        if (index != inter.size()-1)            cout<<inter[index] + inter[index+1]<<endl;        else            cout<<inter[0] + inter[index]<<endl;        index += 2;    }}
