C++从键盘读入数组并存储

读取指定长度的数组

int main()
{
    int n = 0;
    cin >> n;
    int p[n];
    for (int i = 0; i < n; i++) {
        cin >> p[i];
    }
 
    for (int i = 0;i <n;i++)
    {
        cout << p[i];
    }
    cout << endl;
    return 0;
}

读入任意长度的数组

int main()
{
    vector<int>nums;
    int num = 0;
    do {
        cin >> num;
        nums.push_back(num);
    } while (getchar() != '\n');
 
    for (int i = 0;i < nums.size();i++)
    {
        cout << nums[i];
    }
    cout << endl;
    return 0;
}
