則可以預期偽隨機數生成器在隨後的調用中會生成不同的結果序列rand。 相同的兩個不同的初始化seed在隨後的調用中將產生相同的結果序列rand。 如果seed被設定為1,不過每次啟動的程序產生的隨機數都相等,如果給seed指定的是一個定值,生成器將重新初始化為其初始值,在用srand(unsigned int)輸入種子數后產生的才不一樣。一般用為srand((unsigned int)time(NULL)) 產生種子。

C Language: rand function (Generate Pseudo-Random …

Returns The rand function returns a number between 0 and RAND_MAX (inclusive). Required Header In the C Language, the required header for the rand function is: #include Applies To In the C Language, the rand function can be used in the following
Use the srand function to seed the pseudorandom-number generator before calling rand. The rand function generates a well-known sequence and is not appropriate for use as a cryptographic function. For more cryptographically secure random number generation, use rand_s or the functions declared in the C++ Standard Library in .
Seeding the rand() void srand (unsigned int seed) This function establishes seed as the seed for a new series of pseudo-random numbers. If you call rand before a seed has been established with srand, it uses the value 1 as a default seed. To produce a different
Random Number Generation
In C++ (and C), the functions needed from cstdlib are rand() and srand() srand() is used to seed the random number generator (and only needs to be called once). The seed value could be obtained from user input, but usually the best way is to use the time value obtained from the computer’s clock, since that will change frequently (like between runs of the program)

C中,雖然這個值會是[seed, RAND_MAX(0x7fff))之間的一個隨機取得的值。 3) 如果在調用rand()之前沒有調用過srand(seed), 特別推薦 竹筷子也能射穿坦克鋼板? 為何金屬在太空中接觸會焊接起

Running C++ rand and srand on different computers/OS

 · On the same operating system and platform, srand with a specific seed followed by rand will provide the same answer. However, platforms are free to implement rand() using multiple methods. In fact, you’re only guarantee is that it will return a value between 0 and RAND_MAX, which is a platform specific value (although, typically, 32767, it can be any positive number).
