I am stuck on a challenge about creating an account with a related contact. Do I have to make the contact for another account first and then relate it to a different account? I am lost

Hi Team, 

I have the following code which is bringing me headaches :) 

public with sharing class ApexClassHomeWork 
{
    public List<Account> accs {get; set;}
    
    // retrieves the list of accounts backing the page
    public ApexClassHomeWork()
    {
        accs=[select id, Name, BillingStreet, BillingCity, BillingPostalCode FROM Account  WHERE Name LIKE 'Test%' LIMIT 10];
    }
    
    public void createContact(Id acctId)
    {
        for(Integer i=0; i<500; i++)
        {
            Contact c = new Contact(AccountId=acctId);
            insert c;
        }
    }
}

When calling the method "create contact", I get these errors  messages:

1. "LastName is required" - What do I need to update to resolve this issue?

2. "Too Many DML Statements 151"

3.  "Too many query rows: 500001"

Please help !!
 

Hi There,

I am trying to write one trigger.

Like suppose we post some comments on the chatter of lead. While converting that lead the chatter comment(feedItem) is automatically being populated on the chatter of account, contact, and opportunity.

Thanks in Advance
 

Is there any way by which set of user  automatically assigned on the Opportunity Team based on which India state that the account belongs to. If instead they are assigned on the Account team based on the India State that the account is in, can the opportunity team inherit that from the account team?
