, static is limited to hiding, and for variables, static has the following two functions.2) The second function of static is to keep the contents of the variable persistent. Variables stored in the static data area are initialized at the start of the program and are the only one initialized. A total of two variables are stored in static storage: Global variables and static variables, except that, compared to global variables, static can control the visible range of variables, in the final analys

. You can try two ways to see which one is better for you.Keywords should not be repeated 3-6 times in the same form, generally this is considered to be the largest number of keyword repetitions (as if now has changed). So try to avoid repeating your keywords over and over again. This is spam (keyword Trash) for every search engine, and you will be punished for it. Most search engines will allow you to use up to 1000 characters in the keyword tag. In general, using related keywords for each page

the formula: Gray = (binary) XOR (binary >> 1). There is a detailed explanation in this article.below we write both the binary number and the gray code are below, you can see the left of the number of different or the right side of the result is equal to the number of the right.
