Conditional operator[edit]

If we need just set value for any variable in depent of condition, we can use conditional operator. It's shorter than "if" expression many times. Let's see example.

name = "Artiom";
cond = true;
 
//If expression
if(cond){
  name = "Tom";
}else{
  name = "Artem";
}
 
//Conditional operator
name = cond?"Tom":"Artem";

Nested conditional operator[edit]

As 'if' expression so and Conditional operator can be multiple.

name = "Artiom";
cond1 = false;
cond2 = true;
 
//Conditional operator
name = cond1?"Tom":cond2?"Artem":"NoName"
