Catch type error in C ++

How can I check if the result is of the correct type (int, float, double, etc.) and then throw and catch an exception if it is not?

Thanks everyone,

Vlad.

Could you please give more details on what gives you the "result", you can determine what you need from there, and more likely in a better way.

If you really want to check the type, use typeid

. More details here

Following Daniel's post editing model to actually answer the question by pointing out something else ...



From my other comment:

You must do this before you simply have a result. Checking for overflow after is not a good idea. Check for numbers before adding to see if they will overflow or limit input should be less than half the maximum value type

There is no way to know what at runtime with C ++. These were compile time errors.



To answer the second question, you need to manually check for buffer overflows or overflows, or use a more appropriate data type.

The closest you will get is dynamic_cast .
