Question

We can use parameter passing by reference to

a. Return values from functions
b.Supply values to functions
c.Supply values to, and return values from, functions
d.All of the above
e.None of the above

Answer 1

im new to this but i think parameters are what is put into a funciton in order for it to return something ex:

//function to find largest number of two

int largest(int one, int two)
{

if(one >two)
return one;

else
return two;


}

the parameters are int one and int two so i think the answer is

b.
