The rand() function is a pseudo-random number generator function in C/C++, which returns an integer ranging from 0 to RAND_MAX.
The rand() function utilizes the linear congruential generator algorithm, producing a deterministic sequence of random numbers. This means that with the same seed value, the generated random number sequence will always be the same.
The default seed value for the rand() function is 1, and you can use srand() to set a different seed value to change the sequence of random numbers generated.

In a multi-threaded environment, there may be issues with race conditions when using the rand() function because it relies on global variables to store state information. Consider using a thread-safe random number generator to avoid this problem.
