A class with a pure virtual function in C++ is known as an abstract class. Here is an example:

```cpp
class AbstractClass {
public:
// A pure virtual function
virtual void pureVirtualFunction() = 0;
};
```

In this example, `AbstractClass` is a class with a pure virtual function `pureVirtualFunction()`. The `= 0` after the function declaration means that the function is pure virtual, and it makes `AbstractClass` an abstract class.

An abstract class cannot be instantiated, and it is meant to be subclassed. Subclasses of an abstract class must implement all its pure virtual functions.
