hii.. I have a custom field(Number_of_contact__c) on account .I had written a trigger to update the field when a contact is created or deleted ,but it is not working.

trigger C1 on Contact (after insert,after delete) {
    decimal x;
  If (trigger.IsInsert==true){
   
for(contact c:trigger.new){
    If(c.Account!=null){
         Account a =new account();
         a=[select   Number_of_contact__c from account where account.name=:c.account.name];
         if(a.Number_of_contact__c==null){
         a.Number_of_contact__c=0;}
         x=a.Number_of_contact__c ; 
         x=x+1;
         a.Number_of_contact__c=x;
         update a;
