using namespace std;
int sum(int a, int b=42) {
int result = a + b;
return (result);

//calling the function with both parameters

Why not just use the var keyword as the type of the parameters passed in the method? Then we could call the function passing arguments of whatever type we would like. Could that work?

CSS The text-indent property I do not understand why you would use this when the </br> tag takes the text back to the left hand side of the page, and as soon as I start a new class the first line of text in a paragraph even with a class it imprints onto every other paragraph like it or not. Why is this please?
