Question

what is the correct syntax for checking a varable value and then setting a varable in the same condition also checking that new set varables var, all in one if statement?

so basically something like

if(this->somevar > 0 && this->newvar = this->GetNewVar(this->somevar),this->newvar > 0)

i know that is not the correct syntax or at least its not working for me anyway, hence the topic, i am using that as an example, so if this->somevar is null or 0, i don’t want it to execute the next condition which is && this->newvar = this->GetNewVar(this->somevar,this->newvar but instead skip the statement and ignore that part.

what is the correct syntax for something like this?

Answer 1

the logical AND && operator is short-circuited if this->somevar evaluates to zero, meaning the rest of your if expression would not be evaluated in that situation
