Generate random number in a range [0, n) in C?

Question

Looking to make a really simple random number generator method in C. The numbers should be between 0 and 24 and can be for example 14.5f.

Any help would be great, thanks

Answer 1

float getRand() {
  float rnd = rand();
  rnd /= RAND_MAX;
  return rnd * 24.0f;
}

Make sure you seed the random number generator with srand before use.
