(2)字符
字符类型的数据,字符在内存中存储的是该字符的ASCII编码值,由于字符数据存储的就是一个字符的编码数值,所以字符数据也可以当做一个整数。在BLOCKLY中的基本表示形式是用“”引用起来,比如“A”、“”Q、“a”、“b”、“#”、“-”、“。”等。使用双引号将一个数字放在引号里面,其意义也表示该数字,和不用引号表示的意义相同,如“65”和65的意义相同。但是大写字母和对应的小写字母对应的ASCII编码值不同,因此为不同的字符。如“A”、 “a”为不同字母。
同样的,在BLOCKLY的字符输入模块中,允许输入任何形式的字符和数字,只要不超出特定的长度都是合法的。只有在程序执行的时候才检查输入是否正确。
