The ? (Conditional) Operator
The conditonal operator (?) returns one of two values depending on the value of the conditional expression. It works the same as If statement.
Syntax
Conditional expression ? exp1 : exp2
Comparing with if statement:
- if(Conditional expression)
- exp1
- exp1
- else
- exp2
Arguments
- Conditional expression: a boolean expression
- exp1: when the conditional expression is true, this expression will be excuted.
- exp2: when the conditional expression is false, this expression will be excuted.
Examples
1 == 1 ? print(true) : print(false); // return true
//Comparing with if statement
if(1 == 1)
print(true);
else
print(false);
// return true
