你能先把你可以改的错误改了吗 好像未定义的错误  你这个看着都烦了

    scanf("%d",&n);int array[n];

你这是动态数组，要用到malloc,c++中用new,你直接这样是不行的。不知道你要实现什么功能，可以改的

先改了符号啊什么的语法问题吧

#include<stdio.h>
#include<malloc.h>
int main(void)
{
    int n;
    scanf("%d",&n);
    int *array;
    array=(int *)malloc(n*sizeof(int));
    for(int idx=0;idx<n;idx++)
    {
        scanf("%d",&array[idx]);
    }
    int gcd(int x, int y);
int gcds(int *array,int len);
    int now = gcds(array,n);
    printf("%d",now);
    return 0;
}
int gcd(int x,int y)
{
    if(y!=0)
      gcd(y,x%y);
    else
        return x;
}
int gcds(int *array,int len)
{
if(len!=0)
    gcd(*array,gcds(array+1,len-1));
else
    return *array;
}
这是我改的，编译通过了，目测你这是求最大公约数吧，试了几个数，不太合适，估计越界了吧

纠正一下，不是越界，递归看的我有点晕，估计是第二个函数那出错了

#include<stdio.h>
#include<malloc.h>
int main(void)
{
    int n;
    scanf("%d",&n);
    int *array;
    array=(int *)malloc(n*sizeof(int));
    for(int idx=0;idx<n;idx++)
    {
        scanf("%d",&array[idx]);
    }
    int gcd(int x, int y);
int gcds(int *array,int len);
    int now = gcds(array,n);
    printf("%d",now);
    return 0;
}
int gcd(int x,int y)
{
    if(y!=0)
     return gcd(y,x%y);
    else
        return x;
}
int gcds(int *array,int len)
{
if(len!=1)
{printf("gcd(%d,gcds(%d,%d-1))\n",*array,*(array+1),len);
  return  gcd(*array,gcds(array+1,len-1));
}
else
    return *array;
}
这次对了，就是你指针越界了，我修改了几个地方，功能实现了
还有刚才删掉你的（ return）  gcd(*array,gcds(array+1,len-1));是我没理解，抱歉，现在好了
