What does it do?

Question

what does this line of code do in c++?can you please explain IN DETAIL

cout<<Remainder < 0 ? Remainder+(Base*-1) :Remainder;

//Remainder and Base are defined variables...this is a base convertor code.

Answer 1

Remainder < 0 ? Remainder+(Base*-1) : Remainder
This works almost like a if-else statement.
a ? b : c;
is like writing
if(a){
b;
} else {
c;
}
(just that you can't use if-else like this within a cout)

So if Remainder < 0 is true then it will cout << Remainder+(Base*-1);
If Remainder < 0 is false it will cout << Remainder;
