== Why is this an issue?

Implicit casts which do not make sense are likely to be programming errors.


The rule reports an issue for the following implicit casts:

* Boolean to pointer
* Float to boolean
* ``++nullptr++`` constant to integer 


=== Noncompliant code example

[source,cpp]
----
float f();

bool test() {
  int* j = false; // Noncompliant
  bool b = f(); // Noncompliant
  if (b) {
    return j; // Compliant, pointer to bool
  } else {
    return nullptr; // Noncompliant, just return false
  }
}
