Creating a local variable in an if statement?

Question

I'm looking at a function that creates a local variable in an if statement. If someone called that function and the condition to the if statement was not triggered, that local variable wouldn't exist, right?

Answer 1

Yes. It's like other languages it won't exist in out of the scope. solc compiler give you Undeclared identifier error. for example

if (everything) {
   uint testVariable = 1;
}
require(testVariable == 1, "error"); // you will have Undeclared identifier error in here
