.. title:: clang-tidy - readability-redundant-control-flow

readability-redundant-control-flow
==================================

This check looks for procedures (functions returning no value) with ``return``
statements at the end of the function. Such ``return`` statements are
redundant.

Loop statements (``for``, ``while``, ``do while``) are checked for redundant
``continue`` statements at the end of the loop body.

Examples:

The following function `f` contains a redundant ``return`` statement:

.. code-block:: c++

  extern void g();
  void f() {
    g();
    return;
  }

becomes

.. code-block:: c++

  extern void g();
  void f() {
    g();
  }

The following function `k` contains a redundant ``continue`` statement:

.. code-block:: c++

  void k() {
    for (int i = 0; i < 10; ++i) {
      continue;
    }
  }

becomes

.. code-block:: c++

  void k() {
    for (int i = 0; i < 10; ++i) {
    }
  }
