How to print a message in Solidity

Question

So, I am writing a smart contract and in that I am checking a condition. What I want is that when the condition fails or passes I want to send different message in each case. I can not find any printing statements in Solidity. How can I implement this?

Answer 1

You can use the require function to do this. Pass the message you want to print as the 2nd argument:

require(condition, “message to be displayed”)
