Can someone help me with this?

Question

How can I store a mathematical operator inside a variable and then use the variable to do an equation?? (Im using kotlin)
var Operator ="+"
var num1 = 1
var num2 = 2
Print (num1 + operator +num2)

Answer 1

Depends on where you run the code. There is eval function that is part of the JavaScript libraries. However, you can do like I did here and build your own expression parser. It limits the security risks of allowing eval to execute unknown code possibly hacking your program.

You Don't need to store operator in variable...operators are predefined in all programming languages...just put relevant operator for your desired result.
