求助。。为什么编译不通啊

#include <bits/stdc++.h>
using namespase std;
int a[10005],b[10005],g[10005],k[10005];
int n;
int x,y,temp=-1;

{   
    cin>>x>>y;
    cin>>n;
    for(int i=1;i<=n;i++)
       cin>>a[i]>>b[i]>>g[i]>>k[i];
    for(i=1;i<=n;i++)
       {   
           if(a[i]<=x&&a[i]+g[i]>=x&&b[i]<=y&&b[i]+k[i]>=y)
             temp=i;
       }
    cout<<temp;
    return 0;
}
