ASCII编码表
ASCII是英文American Standard Code for Information Interchange的缩写。ASCII码是目前计算机最通用的编码标准。
因为计算机只能接受数字信息,ASCII码将字符作为数字来表示,以便计算机能够接受和处理。比如大写字母M的ASCII码是77。
ASCII码中,第0~32号及第127号是控制字符,常用的有LF(换行)、CR(回车);第33~126号是字符,其中第48~57号为0~9十个阿拉伯数字;65~90号为26个大写英文字母,97~122号为26个小写英文字母,其余的是一些标点符号、运算符号等。
以下是常用的ASCII码对照表:
