hash – How you can generate a coinbase transaction?

I’m making a miner in C++ for solo mining, and am struggling to create the right coinbase transaction.

Say I’ve a bc1 deal with, like bc1qfc7fameteuguetm0kfzypnvf2ju6wppdvj6tkc , what can be and instance of a coinbase transaction with this, and the way would I get to it?

| 00000000000000000000000000000000 ...  Earlier outpoint TXID
| ffffffff ............................ Earlier outpoint index

| 00000000 ............................ Sequence // i assumed this was all Fs?

01 .................................... Output depend
| 2c37449500000000 .................... // coinbase worth
| ????????????????? ............. // right here, how do i correctly fill this half??
| 00000000 ............................ Locktime

These are the components wanted to create the info for the transaction.

All the pieces as much as the output, i perceive. however i dont know what to place between the coinbase worth and locktime. how does the deal with convert to hex? what OP codes do i want? and is that this transaction format appropriate?

After which I might then hash it and enter it as a brand new transaction into the block as like so,

tx = {
  "knowledge" : "<hex string talked about above>",
  "hash" : "<double sha256 of information above>",
}

is that the one knowledge i want for the json?

Thanks upfront.
