Error in code which is not specified by compiler

#1

I am getting error which is not specified by coding blocks compiler.
#include
#include
using namespace std;
int main() {
long int n;
cin>>n;
long int a[n],i;
for(i=0;i<n;i++)
cin>>a[i];
sort(a,a+n);
cout<<a[n-1];
return 0;
}
But if i run the same code in code blocks then this code is ruuning smoothly.
