2016年1月27日 · In most contexts, if you have an array a, then a is short for &a[0]. (There are some exceptions, such as with sizeof a or &a). So **pp really means **&pp[0]. &pp[0] is the address of pp[0], so *&pp[0] is equivalent to just pp[0], so **&pp[0] is equivalent to *pp[0].

2020年10月28日 · If the BIOS has set the lock bit on the Turbo Power Limits or on the PP0 Current Limit, there is no easy way to unlock this register after you boot up into Windows. You would need a modified BIOS or you would have to try and find these locks in the UEFI variables.

后边的数值设置范围为 0-255，0 代表最高性能，255 代表最大电能节省和最低性能。具体效果可以在一些负载任务的时候观察到，如果设置为 0，cpu 倾向于全程满睿频，255 会使得 cpu 有负载也会保持较低频率。通过降低该数值可以解决某些情况的降频。

2023年1月13日 · For example, if you choose $0^p10^p1$ you can be ensured that $xy$, and in particular $y$, contain only $0$s that appear before the first $1$. Then pumping $y$ yields a word that is not in the language. $\endgroup$ –

2020年8月18日 · Intel CPUs have a power limit for the entire CPU package which includes everything including the Intel GPU. The two PP0 limits are separate limits that only apply to to the cores. You can use these to set either a power consumption limit or a limit of how much current can flow through the cores.

2023年8月1日 · put 256 in pp0 current limit. If it doesn't let you do it, you need to unlock pp0 from bios.

2023年8月27日 · Set the PP0 Power Limit to 0, press Apply and then clear the PP0 Power Limit check box and press OK. There is no need to use these settings. Do not check Sync MMIO. Check the MMIO Lock box near the top right of the TPL window instead. Set the Turbo Time Limit to a value that the CPU understands, 28 seconds.

#include <stdio.h> #include <assert.h> int main(){ char* p = "abc"; char** pp[2]; pp[0] = &p; assert(*pp[0]==**pp); printf("Comparison: %s, %s\n",**pp, *pp[0]); return 0; }

2013年4月5日 · *p++!='\0' 首先是运算符优先级的问题，* ，++同一优先级； 那么再看结合性，自右向左，也就是说先执行++，再执行*； 那么再看++的含义，p++是后加加，它会先使用，再自增，也就是说，从运算符来讲是先++再*，但因为++的实际含义，导致实际效果是先*P 然后p++。
