果决定执行下面的哪一种操作,这就用到选择结构程序。通常用IF 语句来实现选择结构的程序设计。 2、讲授,选择结构语句——IF语句(1)IF语句的格式 IF条件THEN 语句组A [ELSE 语句组B] ENDIF (2)执行过程 Ⅰ、执行IF语句时,先判断所给条件是否成立,如果判断条件 ...
通常用IF语句来实现选择结构的程序设计。 2、讲授:选择结构语句——IF语句 (1)IF语句的格式 IF条件THEN 语句组A [ELSE 语句组B] ENDIF (2)执行过程 Ⅰ、执行IF语句时,先判断所给条件是否成立,如果判断条件为是,则执行语句A,然后跳过ELSE行和语句B,直接执行ENDIF后的语句。 Ⅱ、如果判断条件为否,则跳过THEN...

Technology has moved on, and now most people would steer you towards Python if you wanted to get your feet wet with software development. But for those who got their first taste of programming by copying lines of BASIC out of a computer magazine, the language still holds a certain nostalgic...
