x:=x;
整个公式是
WhilePrintingRecords; Shared numbervar x; x:=x;
但它没有给出任何输出。提前致谢!
该x:=x;部分通常用于设置x例如的值:
x
WhilePrintingRecords; Shared numbervar x; x:=10;
运行此代码设置变量并返回值集(只要只设置了一个变量),还返回您可以添加的变量的值:
WhilePrintingRecords; Shared numbervar x; x:=10; x
或者,如果变量设置在其他地方,要返回值,您可以执行以下操作:
WhilePrintingRecords; Shared numbervar x; x
