输出数组仅显示最后一个元素，而不是在数组中的指定位置插入数据

Question

#include <iostream>
using namespace std;

#define max 10

int main()
{
    int items[max];
    int i,n,ub,location,data;

    cout<<"Enter the number of items you want to enter: "<<endl;
    cin>>n;

    ub=n-1;

    if(ub>=max-1){
        cout<<"Array is full!"<<endl;
    }

    else{
        cout<<"Enter "<<n<<" elements:"<<endl;
        for(i=0;i<n;i++){
            cin>>items[n];
        }

        cout<<"Enter the location where you want to insert:"<<endl;
        cin>>location;
        cout<<"Enter the data you want to insert in location "<<location<<endl;
        cin>>data;

        while(ub>=location){
            items[ub]=items[ub-1];
            ub--;
        }

        items[location]=data;

        cout<<"The array after insertion is as follows: "<<endl;
        for(i=0;i<n;i++){
            cout<<items[n]<<endl;
        }
    }

}

对于 n=5 的输入数组，假设为 {1 ,2 ,3 ,4 ,5 }，我想在数组的位置 2 插入 data=19，使得输出为 {1,19,3 , 4, 5} 但我得到的输出是 {5 ,5 ,5 ,5 ,5}。我该如何解决这个问题？

Answer 1

你有两个问题：

1. cin>>items[n]; 必须是 cin>>items[i];
2. cout<<items[n]<<endl; 必须是 cout<<items[i]<<endl;
