| Clone | ||

| Example | ||
| ======= | ||
|
|
||
| .. code-block:: C++ | ||
|
|
||
| extern int array_a[]; | ||
| extern int array_b[]; | ||
|
|
||
| int sum_a = 0; | ||
|
|
||
| for (int i = 0; i < 4; i++) | ||
| sum_a += array_a[i]; | ||
|
|
||
| int average_a = sum_a / 4; | ||
|
|
||
| int sum_b = 0; | ||
|
|
||

| Importance | ||
| ========== | ||
|
|
||
| Code clones make editing more difficult due to unnecessary increases | ||
| in complexity and length. | ||
|
|
||
| How to fix this | ||
| ========== | ||
|
|
||
| Usually code clones can be simplified to only one occurrence. In a | ||
| lot of cases, both just use different values or variables and can | ||
| be reduced to one function called with different parameters or | ||
| loops. | ||

| Redundancy | ||
| ========== | ||
| This aspect describes redundancy in your source code. | ||

|
|
||
| Redundant code makes your code harder to read and understand. | ||
|
|
||
| How to fix this | ||
| ========== | ||
|
|
||
| Redundant code can usually be removed without consequences. | ||
