Syntax (false_value, true_value)[conditional_expression] In this case, the false_value and true_value form … These operators evaluate something based on a condition being true or not. :’ takes three operands to work, hence they are also called ternary operators. And, if condition is false, expression2 is executed. Our mission: to help people learn to code for free. Hence value of variable 'b' i.e. Consider the following code: int a = 1, b = 2, ans; if (a == 1) { if (b == 2) { ans = 3; } else { ans = 5; } } else { ans = 0; } printf ("%d\n", ans); Here's the code above rewritten using a nested ternary operator: int a = 1, b = 2, ans; ans = (a == 1 ? Nested ternaries can be simulated as c (expr1,expr2,expr3) [which.first ((c (cond1,cond2,TRUE))] where the function which.first returns the index of the first true value in the condition vector. We can use the ternary operator in place of if-else conditions or even switch conditions using nested ternary operators. consequent : alternative x = condition ? From the above syntax, they are condition, value_1 and value_2. scala. The ternary construct returns expression1 as an output if the first operand evaluates to true, expression2otherwise. After that, we have a question mark (?). and : symbols. Get started, freeCodeCamp is a donor-supported tax-exempt 501(c)(3) nonprofit organization (United States Federal Tax Identification Number: 82-0779546). : At first, the Python Benevolent Dictator For Life (I mean Guido van Rossum, of course) rejected it (as non-Pythonic style), since it's quite hard to understand for people not used to C language. What is ternary operator (? [on_true] if [expression] else [on_false] In C++, it looks like this: max=(a>b)?a:b. Remember that the arguments value_if_true and value_if_false must be of the same type, and they must be simple expressions rather than full statements. condition ? b : nothing? If it is false, the result of Expression2 is returned. PHP's behaviour when using more than one ternary operator within a single statement is non-obvious compared to other languages.
