生成一个随机数

声明

int random(...)

参数

参数名	描述
...	可传入 0-3 个参数（分别代表生成范围为[0, _I64_MAX], [0, UP], [LOW, UP]）

返回值

生成的随机数，分布范围由参数确定

使用方式

seed = random();
    printf(HIG "EXAMPLE: Generate 64bit random values with same seed" NOR "\n");
    auto m64_1 = mt_random.create_instance(seed, false);
    auto m64_2 = mt_random.create_instance(seed, false);

    for (int i = 0; i < 10; ++i)
    {
        int r1 = m64_1.random();
        int r2 = m64_2.random();
        printf("    value1: %d, value2: %d\n", r1, r2);
    }

    // The random result in specific range
    printf(HIG "EXAMPLE: Generate random values in specific range" NOR "\n");
    auto mr = mt_random.create_instance(1);
    for (int i = 0; i < 10; ++i)
    {
        int r1 = mr.random(50);
        int r2 = mr.random(1,100);
        printf("    value1[0,50]: %d, value2[1,100]: %d\n", r1, r2);
    }
