The Operator: ? :

Question

Need some help on how to break this problem down.

What is the value of x after this code?
int x = 5;
int y = 3;
x = (x > y) ? y : x;

Answer 1

The ?: operator is pretty much like an if-else statement. Maybe it helps if we rewrite it, like so:

int x = 5;
int y = 3;

if (x > y) {
x = y;
} else {
x = x;
}

The value of x would be 3 then :)

Answer 2

int x = 5;
int y = 5;
if (x > y) {
x = y;
}
else {
x = x;
}

This is called ternary operator!
if x>y is true then it will return the element before the ":" (colon) and if that's false then it will return the element after the colon

Answer 3

X=3
(5>3 Is true)

Answer 4

This is called a ternary operator, imagine it as an if statement, but shorter.
