Half of the Christmas tree

carrotcake (2)
Hello guys!

I'm really struggling how to get a half of a christmas tree, like if you'd cut a tree in a half then print out only the left side.

I've managed to do it but in a very uggo way.

I know that there must be some pattern in this and I know that I need
to make a for loop to print one star then two starts etc. but I can't figure it out for the world! I'm giving aways my solution and I'll appreciate your help.

using namespace std;

int main(int argc, const char * argv[]) {
    
    int j = 5;
    for (int i = 0; i < j; ++i)
    {
        cout << " ";
    }
    
    cout << "*\n";
    j--;
    
    for (int i = 0; i < j; ++i)
    {
        cout << " ";
    }
    
    cout << "**\n";
    j--;
    
    for (int i = 0; i < j; ++i)
    {
        cout << " ";
    }
    
    cout << "***\n";
    j--;

    for (int i = 0; i < j; ++i)
    {
        cout << " ";
    }
    
    cout << "****\n";
