Hasard 是一个伪随机码生成器 (PRNG) 类库。支持的随机算法包括:Park-Miller, Mersenne Twister, Linux device (/dev/urandom or /dev/random) 等等。
示例代码:
# **include** **< hasard.h>** # **include** **< stdio.h>** **int** **main** () { **struct** hasard_t *rnd; rnd = hasard_new(HASARD_FAST); printf( **"Heads or Tails? %s!\n"** , hasard_bool(rnd)? **"Heads"** : **"Tails"** ); printf( **"Dice: %i\n"** , hasard_int(rnd, 1, 6)); printf( **"Integer in 0..999: %u\n"** , hasard_ulong(rnd, 0, 999)); printf( **"Float in [0.0; 1.0]: %.3f\n"** , hasard_double(rnd, 0.0, 1.0)); hasard_destroy(rnd); **return** 0; }
