ASCII码即美国标准信息交换码(AmericanStandardCode forInformationInterchange),计算机只能理解数字,因此一个ASCII码就是一个字符, 如:'a' 或 '@' 的数字表现形式,也可表示某种动作。ASCII码出现较早,非打印字符的使用也不再出于最初的目的。以下是ASCII码字符表,其中包括对前32个非打印字符的描述。当初设计ASCII码...
ASCII（American Standard Code for Information Interchange，美国信息交换标准代码）是用于电子通信的标准字符编码系统，它包括了128个或256个字符，用7位或8位二进制数表示。ASCII编码的应用非常广泛，在计算机编程中，它常被用来表示和处理文本信息。ASCII码将字符分为几个部分，包括：控制字符：用于控制程序流程的字符...

Short for American Standard Code for Information Interexchange, ASCII is a standard that assigns letters, numbers, and other characters in the 256 slots available in the 8-bit code. The ASCII decimal (Dec) number is created from binary, which is the language of all computers. ASCII (/ˈ...
Numeric values 0 through 127 represent digits 0 through 9, letters of the alphabet, punctuation marks, and other special characters. Some AutoLISP functions return or expect an ASCII code for a single character instead of the string equivalent. For example, the grread function returns the ASCII...
In digital cryptography, the letters can be replaced by the numbers which can be assigned by the sender. In this chapter, the message (plaintext) will be replaced by their ASCII codes before the encryption. As the ASCII code table has 128 characters, we define the formula for the cipher...
