Can I do this?


the function I'm calling, is returning a 3, but the variable in the while loop is equal to 1...
I'm not sure what is happening in this statement, Originally I thought it would just always evaluate to true and loop forever since, variable would be successfully set to functionCall()'s return value, therefore evaluating to 1, and 1 does not equal zero, so that too would evaluate to 1 (true) and loop forever... but it sets variable to 1 and then exits the while loop--what's going on?

functionCall() gets input from the user so I can only call it once really, I was going for while(functionCall()!=0){ } , but then I wouldn't be able to check the return value within the loop. I could do something else but I wanted to use this method, so I'm just wondering what it's actually doing.

no way, variable is set to true, because functionCall()!=0 is true. in this case true means 1

p.s. And yes, this does loop forever if functionCall() really returns 3

you should try something like this:
...
because it seems to me that variable is given the value of evaluation: functionCall()!=0, so you just need to use one more pair of brackets...
I hope this helps

@da penguin, oh right, I forgot about right->left order, and you're right it was looping forever--there are two loops working together and I was mistaken with which loop I was in at what time.

@Alibeg, it worked great, thank you!
