# V596\. Object was created but is not used\. Check for missing 'throw' keyword\.

The analyzer has detected a strange use of the std::exception class or derived class\. The analyzer generates this warning when an object of the std::exception / CException type is created but not being used\.

For example:

```cpp
if (name.empty())
  std::logic_error("Name mustn't be empty");
```

The error is this: the key word 'throw' is missing by accident\. As a result, this code does not generate an exception in case of an error\. This is the fixed code:

```cpp
if (name.empty())
  throw std::logic_error("Name mustn't be empty");
```
