Functions

A function declaration in solidity looks like the following:

function eatHamburgers(string _name, uint _amount) {

}

This is a function named eatHamburgers that takes 2 parameters: a string and a uint. For now the body of the function is empty.

Note: It's convention (but not required) to start function parameter variable names with an underscore (_) in order to differentiate them from global variables. We'll use that convention throughout our tutorial.

You would call this function like so:

eatHamburgers("vitalik", 100);
