I am doing the cryptozombies.io course on Solidity.
In Chapter 7 of Making the Zombie Factory, it introduces function declarations. The instructions on this chapter are:
Create a public function named createZombie. It should take two parameters: _name (a string), and _dna (a uint). Don't forget to pass the first argument by value by using the memory keyword
My question is why is the
_name parameter required to be declared with keyword
memory (and similarly, why is the
_dna parameter NOT required to be declared with keyword
In general, when does one declare a parameter using keyword
memory and without it? I did Google about the
memory keyword but I did not understand when it should be used and when it shouldn't.
