.. 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) {
}
}
