Input a number from a user
The user can continue input a number until input ‘-1’
If -1 is entered, the program must show entered numbers

最佳回答：

 #include <stdio.h>
int main()
{
    int arr[10000];
        int n;
        int i = 0;
        while (true)
        {
            printf("Number ? ");
            scanf("%d", &n);
                arr[i++] = n;
                if (n == -1) break;
        }
        i = 0;
        while (arr[i] != -1)
            printf("%d,", arr[i++]);
}
