In C++, rand() and srand() are used for generating random numbers. The rand() function returns a pseudo-random integer between 0 and RAND_MAX (a constant typically set to 32767). However, the randomness of rand() is predictable and not truly random, as it uses an internal seed value to generate numbers.
To produce different sequences of random numbers each time a program runs, srand() is used to set the seed for the random number generator. It takes an integer value as an argument, usually the current time, which ensures that the seed changes with every execution. Commonly, srand(time(0)) is used, where time(0) provides a time-based seed.
Without setting a new seed, calling srand() with the same value repeatedly will produce the same sequence of numbers. Together, rand() and srand() allow for more dynamic and varied random number generation in C++
