Declare

return_type func_name(parameters)
{
	code
	return output;
}

bool yesOrNo(int thing1, bool thing2 = false)
{
	code
	return true;
}

Note: the return type void means there doesn't need to be a output

Note: defaults must be at the end

Inline

This makes it so that when you call a function,

the compiler will place the block of code where the function was called

inline
void funcName()
{
	code
}

Overloading

You can declare multiple functions,

all with different parameters,

cpp will automatically switch between the functions depending the arguments given.

It will switch based on...

1. the number of arguments

2. the variable types
