    Instead of using a for loop paired with push_back() (which can result in allocations that could otherwise be avoided), use the explicit constructor, std::vector<T>(int) (requiring direct initialisation via a parenthesised list) which constructs a std::vector of a given size:

    int main()
{
    int size {};
    std::cin >> size;
    
    // Constructs a 'std::vector' of given size
    std::vector<int> v (size);
    
    // Loops through the vector by reference
    // setting its elements to inputted values
    for(auto& i : v)
        std::cin >> i;
        
    std::sort(v.begin(), v.end());
    
    for(auto i : v)
        std::cout << i << ' ';
    
    return 0;
}

    int main() { /* Enter your code here. Read input from STDIN. Print output to STDOUT */
    vectorv;

     int n;
 cin>>n;
 for(int i=0;i<n;i++) {
     int ele;
     cin>>ele;
     v.push_back(ele);
 }

 sort(v.begin(),v.end());

 for(int a : v) {
     cout<<a<<" ";
 }

return 0;

    }
