Rewrite the code using ternary operators

Question

if(i%2==0)
sum=sum-(int)k;
else
sum=sum+(int)k;

Answer 1

no all languages have ternary operator, and you don't provide the targeted one ^^

anyway, for languages that support it, ternary syntax commonly look like:

sum = i%2==0 ? sum-k : sum+k

for those wich doesn't support it, often you could inline if..else in the right hand side of an assignement (but syntax sligthly differ depending on language)

Answer 2

visph pseudocode but I think he wants python? or c?

Answer 3

you have a language for us?
sum - = int(k) if i%2==0 else sum+=int(k)

Answer 4

value_if_true if condition else value_if_false

Answer 5

visph kotlin has none?
That's suprising!
thought it was Java under the hood. You found a reason for it?

Answer 6

In java,
using ternary operator,

sum = i%2==0 ? sum-(int)k : sum+(int)k ;

Answer 7

Jayakrishna🇮🇳 yes, that's what I was thinking, so I trust you easily ;)

just I'm not enough aware of Java (nor Kotlin) to answer without doubt (Kotlin wich I seen yesterday that ut doesn't have, surprising me and make me less sure that Javas has one)

Answer 8

Frogged for what language is your example of inlined if..else?

Answer 9

Java

Answer 10

Neeta Maddheshiya I don't know if java has one or not: Kotlin doesn't have (I discovered that yesterday), and instead use:

sum = if (i%2==0) sum-k else sum+k

(assuming sum and k are of same type)

Answer 11

Frogged the same reason as python: a design choice ^^

Answer 12

Jayakrishna🇮🇳 I was not sure for Java, because I was thinking it has a ternary, but not Kotlin, so that make me doubt ^^

Answer 13

visph Frogged

Java has it: https://www.baeldung.com/java-ternary-operator

Neeta Maddheshiya

See if you can do it by your own after reading about ternary on the site. If not, just ping me.

Happy coding!

Answer 14

visph Java have ternary operator ?:
Am sure, it works..
I don't know about kotlin have it or not ..

Answer 15

visph frogged used python

Answer 16

Nor'wester 🌪️ 🇧🇩 are you sure?
because OP code seems not to be python ^^ (or invalid python ;P)

Answer 17

Frogged thanks... I was thinking it was python, but as previously said, I don't think it is the expected language by OP:

+ no colon at end of if/else statements
+ no indentation
+ use of cast by prependind type inside parenthesis

Answer 18

sorry for the typo corrected just after posting ;P
