The method for comparing floating-point numbers with 0 equals that of 0. Check whether the floating point number is 0 in C #. Do not use "=" or "! = "For comparison, is there no way to do this when the value is 0? The following two judgment ideas are shown:Approximate comparison Take the discount method and try to conv

In fact, very early in the look at Linux to see this thing, and later in the Li Xianjing "System programmer growth Plan" saw a similar definition, so in mind to summarize, the results found that the online has been a good summary of cattle, and then turned over, thank you for sharing, this is my driving force!At the same time, it needs attention: ISO/IEC 9899-1999, it is illegal to write this, this is only the extension of GNU C, GCC can allow the existence of this grammatical phenomenon. (C99 a

today, I encountered a problem that I have never noticed before, Program : const char * CP = "some value "; while (* CP) { // do something to * CP ++ CP; } The ASCII code of '/0' is 0, which is also called in C ++NULL character, The output result is similar to a space with no information. It is not a space; The test is as follows:Char A = '/0 ';Cout If (A

Thread. Sleep (0), Thread. Sleep (0) The article I saw was well written. We may often use the Thread. Sleep function to suspend the Thread for a period of time. Do you understand the usage of this function correctly? Consider the following two questions:Suppose it is 12:00:00. 000. If I call Thread. Sleep (1000), this Thread will not be awakened at 12:00:01. 000?Someone's Code uses a seemingly unknown sent
