• The best way to generate random numbers in C is to use a third-party library like OpenSSL. For example ... 1. C - random number generation. 1.
  • Next(int, int). Returns a positive random integer within the specified minimum and maximum range (includes min and excludes max).
  • Though it looks random to the user the programming language offers us the mechanism to define the range of the random number.
  • The function rand() can be used to generate a pseudo-random integer value between 0 and RAND_MAX (0 and RAND_MAX included).
  • To handle these scenarios, both in C and C++ you can generate random numbers using the rand() function, which produces a pseudorandom integer.
  • Hence, we need to simulate randomness. In order to simulate randomness, we make use of pseudo-random number generator (PRNG) which is in-built in C++.
  • For a given seed value, the function generates same sequence of random numbers. Random numbers lie between 0 and RAND_MAX.
  • Generating a random number is not necessarily difficult, but generating a truly random number can be challenging.
  • For using the Random class, the important part to remember is that you should create the class once. Then reuse it to get a random stream of numbers.
  • The value generated by the random number generator function is an integer which can be extremely long. Hence, you can use float or double values.
