Answer 1

Have you figured it out?
So I tried finding that question (I slightly remember being similar), but I can't find it anymore, I didn't bookmark the thread either unfortunately.

But I found some links, might be helpful, there is the easy way and there's also the bit more complex way, but since you wanted this, it shouldn't be a problem.

I still don't understand why you want to check variable type though, since C++ is statically typed language - you know already what type something is as you declare it in code.

Answer 2

Then you shouldn't have that many languages specification in Relevant Tags unknown .

Answer 3

if (typeof a == typeof b)

Answer 4

Ok Ipang . Do you have the answer for this?

Answer 5

unknown
What exactly did you mean by comparing data type in expression? you want to check if the variables' type are all the same or what?

I remember slightly a question asking how to check for a variable's type, but that is not comparing the data type. Elaborate some more on this thought will you?

Answer 6

Yes i want to check the data type of the two variables, weather they are same or not? Ipang
