Dart Conditional Expression: Ternary Operators

A ternary operator is a conditional operator that takes three operands:

a condition followed by a question mark (?), a result expression to evaluate if the condition is true, followed by a colon (:), and another result expression to evaluate if the condition is false.

The syntax of the ternary operator is:

condition ? expression1 : expression2

Here's how it works:

• If the condition evaluates to true, expression1 is executed.

• If the condition evaluates to false, expression2 is executed.

• Ternary operators are often used as shortcuts for simple conditional statements, providing a more concise way to express conditional logic, especially in cases where the if-else statement would be repetitive or verbose. They are particularly useful when assigning values based on conditions or when returning values from functions based on conditions.

• 

  • int max = num1 > num2 ? num1 : num2; is the ternary operator.

  • It checks the condition num1 > num2. If this condition is true, it assigns the value of num1 to max; otherwise, it assigns the value of num2.

  • So, if num1 is greater than num2, max will be assigned the value of num1; otherwise, it will be assigned the value of num2.

  • Finally, it prints the result using print("The greatest number is $max");.
