# V1015\. Suspicious simultaneous use of bitwise and logical operators\.

The analyzer has detected a suspicious expression that uses logical and bitwise operations at the same time\. One of those operations is probably mistyped\.

Consider the following example:

```cpp
void write(int s);
void write(unsigned char a, unsigned char b,
           unsigned char c, unsigned char d)
{
  write((a << 24) | (b << 16) || (c << 8) | d);
}
```

This is obviously a typo: the programmer used the '\|\|' operator instead of '\|' by mistake\. The fixed code:

```cpp
void write(unsigned char a, unsigned char b,
           unsigned char c, unsigned char d)
{
  write((a << 24) | (b << 16) | (c << 8) | d);
}
```
