检查数组的所有内容是否在一个数字范围内，没有重复

Question

我需要一种方法来查看用户输入的所有数字是否都是从 1 到 15 的数字。没有重复。

到目前为止我有一个程序可以检查数字是否超过 15 或小于 1，但我不知道如何检查输入数组的每个数字，看看是否已经输入数组了

这是我目前所拥有的。

#include <iostream>
using namespace std;
int main() {
    bool somethingBadHappend=false;         //booleans like this make it easy for the program to be read
    int numbers[15]{};
    cout << "enter 15 numbers:";
    for (int i = 0; i < 15; i++)
    {
        cin>>numbers[i];                    //entering them into the array
    }

 
        if (numbers[i] > 15|| numbers[i]<=0)
        {
            somethingBadHappend = true;
        }
    }

    if (somethingBadHappend)      //see the perfect use of code here?
    {
        cout<<"NOT GOOD";           // How elegant!
    }
    else
        cout<<"GOOD";

    return 0;
}

如果我理解你的问题，你必须再次检查数组以查看重复项。

#include <iostream>
using namespace std;
int main() {
    bool somethingBadHappend=false;         //booleans like this make it easy for the program to be read
    int numbers[15]{};
    
    cout << "enter 15 numbers:";
    for (int i = 0; i < 15; i++)
    {
        cin>>numbers[i];                    //entering them into the array
    }

//to find values >15 or <1
    for (int i = 0; i < 15; i++)
    {
        if (numbers[i] > 15 || numbers[i]<=0)
        {
            somethingBadHappend = true;
        }
    }
//to find the duplicate into array
        for (int i = 0; i < 15; i++){
                for(int c=0; c<15; c++){
                    if(i!=c){ // check the different index
                        if(numbers[i]==numbers[c]){
                            somethingBadHappend = true; //found duplicate
                            break;
                        }
                    }
                }
            }

    if (somethingBadHappend)      //see the perfect use of code here?
    {
        cout<<"NOT GOOD";           // How elegant!
    }
    else
        cout<<"GOOD";

    return 0;
}

检查数组的所有内容是否在一个数字范围内，没有重复

Check if all content of arrays are between a range of numbers, without duplicates
