error: non-aggregate type vector<int> cannot be inititalised with an initialiser list

I am writing C++ code in vs code on my Macbook. While using the C++ standard template library, i am writing the code

#include<iostream>
#include<vector>
using namespace std;
int main()
{
    vector<int> array={1,3,4};
    for(int x:array)
    cout<<x<<" ";
    return 0;
}

This code, on compilation gives the error that:

non-aggregate type vector<int> cannot be initialised with an initialiser list.

But when I re-write the code as below, it works totally fine.

#include<iostream>
#include<vector>
using namespace std;
int main()
{
    vector<int> array;
    int val;
    int n;
    cout<<"Give me n:";
    cin>>n;
    for(int i=0;i<n;++i)
    {
        cin>>val;
        array.push_back(val);
    }
    return 0;
}

In addition, I tried doing this in JetBrains Clion IDE, and I see that both versions of my code are working fine. Why this problem is happening?

But when i write this same code as:

The other version is not really the same code.

Your problem is with std::vector initializer list, probably arising from wrong compilation flags passed to your compiler. If you're using mac, try to download and install clang, then compile and run it. If it dosen't work then re-post.
