# V1057\. Pseudo random sequence is the same at every program run\. Consider assigning the seed to a value not known at compile\-time\.

The analyzer has detected suspicious code initializing the pseudorandom number generator to a constant value\.

```cpp
// C
srand(0);
// C++
std::mt19937 engine(1);
```

When initialized in such a way, the generator will be producing a predictable sequence of numbers or the same number at every run\.

To avoid this, assign the seed to some random number such as the current system time:

```cpp
srand(time(0));
```

However, this approach may lead to issues in multithreaded applications: 'time\(0\)' may return identical values in different threads\. Also, keep in mind that the user could change the time settings\.

Starting with C\+\+11, the 'std::random\_device' generator is available, which implements an interface to the true\-random number generator:

```cpp
std::random_device rd;
std::mt19937 engine(rd());
```

However, if your system lacks such a generator, the regular pseudorandom number generator will be used\.
