Do we need to use code In different coin...
I am having a hard time interpreting your question but I will try to answer it according to my perception. Since you are asking if we need to use code in different coin, do you want to ask if you need to have coding skills when creating your own coin? The answer to your question is yes, may it be a bitcoin forked one or not(even if it is made from eth smart contract or not), everyone who plans to develop their own altcoin would need to have programming skills to succeed in creating one.
