Trigger to create new contact when new account is inserted

This post explains how to create a new related contact when account is inserted in salesforce.

⇒ " This trigger creates a new contact(With same account name) whenever new account is inserted ..Number of new contact created is depend on NumberofLocations__c(Account field) and all contact name will be Team_AAA"

trigger Contact_Create on Account (after insert) {

list<Contact> New_Contact = new list<Contact>();

map <ID,Decimal> acc = new map<ID,Decimal>();

for(Account a : trigger.new)

{

  acc.put(a.id, a.NumberofLocations__c);

}

   for(Id x : acc.keyset())

   {

      for(Decimal z=0; z<acc.get(x); z++)

      {

       New_Contact.add (new Contact(AccountId=x, LastName='Team_AAA'));

      }

  }

      insert New_Contact;

}

                   Here I've created one new Account with name Microsoft with NumberOfLocation equals 4

After insert this account trigger will fire and create 4 new contact with name Team_AAA with account name Microsoft

Trigger to prevent creating duplicate accounts in salesforce

This post explains how to prevent creating duplicate accounts in Salesforce.

Trigger :

trigger Prevent_duplicacy on Account (before insert) {

  Set<string> str=new Set<string>();

    for(Account acc:trigger.new)

    {

        str.add(acc.name);

    }

    

    List<Account> acc= new List<Account>([select name from Account where name in:str]);

    

    for(Account a:trigger.new)

    {

        if(acc.size()>0)

        {

            a.adderror('error');

        }

    }

}

As I already have an account named Microsoft in my org.. When I am trying to create a new account with same the name it shows an error.

Thanks,
