Can you please look into the code and point out what is the error

#1

#include
using namespace std;
int Findindex(int*a,int n,int i,int key){
if (i==n){
return -1;
}
if (a[0]==key){
int bi= Findindex(a,n,i+1,key);
if (bi!= -1){
return bi;
}
return i;}
}
int main() {
int n,key;
int i;
int a[n];
cin>>n;
for(int i=0;i<n;i++){
cin>>a[i];
}
cin>>key;
cout<<Findindex(a,n,i,key)<<endl;
