ansi syntax

Article reprinted from: http://www.cnblogs.com/huangjacky/archive/2012/05/04/2482529.html the difference between C–kr C and ANSI C Recently in the book "C and Pointers", the book has repeatedly mentioned Kr C,ansi C we often hear, and this is not very clear, I have to go to Baidu, especially to do the following record. The C language was designed and implemented by Dennis M. Rit

ASCIIIn a computer, all data is stored and computed using binary numbers (because the computer represents 1 and 0, respectively, with high and low levels), for example, 52 letters (including uppercase) such as a, B, C, D, and 0, 1, and other commonly used symbols (such as *, #, @ And so on in the computer is also used to store the binary number to represent, and specifically which binary numbers to indicate which symbol, of course, everyone can contract their own set (this is called code), and i

Ansi string we are most familiar with, English occupies one byte, Chinese characters 2 bytes, ending with a \ 0, commonly used in txt text files.Unicode string. Each character (Chinese character or English letter) occupies 2 bytes. In the VC ++ world, Microsoft prefers Unicode, such as wchar_t.UTF8 is A form of Unicode compression. English A is expressed as 0x0041 in unicode. In English, this storage method is too wasteful because it wastes 50% of spa

As we know, C uses a char data type to represent a 8-bit ANSI character, and by default when a string is declared in the code, the C compiler converts the characters in the string into an array of 8-bit char data types: Copy Code code as follows: An 8-bit character char c = ' A '; An array of 8-bit character and 8-bit terminating zero Char szbuffer[100] = "A String"; Microsoft's C + + compiler defines a built-in data ty

Today engaged in Sxna, encountered the problem of coding conversion, engaged in one hours, experienced hardships, finally summed up the following Chinese characters converted to various UTF-8 Unicode ANSI coding program. Do not dare to enjoy the exclusive, hereby dedicate to everyone programming enthusiasts! -------------------------------------------------------------------------------- Matches Google's UTF code Chinese characters go through encode

Since the contact programming, has been to the coding knowledge smattering, always has not mastered the essence.For example: the relationship between ANSI and GBK, what is the relationship between GBK and gb2312, what is the difference between ANSI and UTF8, what is the relationship between Unicode and UTF8, and ANSI, GBK, gb2312, UTF8 (with or without BOM), UTF1

Integral upgrade in ANSI C char,short int or int-bit segments (Bit-field), including their signed or unsigned variants, as well as enumeration types, can be used in an expression that requires an int or unsigned int, if the int can fully represent all the values of the source type. The value of that type is converted to int, otherwise it is converted to unsigned int. An ordinary arithmetic conversion in ANSI
