求解运行时的问题。daltA1没算进去

ttt

我的程序没有出现错误，运行的时候有两个问题：
1.不知道为啥daltA1没算进去
2.A3和daltA1循环的时候位置对调，结果就不一样
谢谢大家关注，以下是我的程序

让别人熟悉你的代码是一件困难的事情，何况没有任何注释。

第一
do k=1,100
       daltA1=daltA1+0.001
       do i=1,int(0.2/0.001)
          A3=A3+0.001
这里的 daltA1 和 A3 位于不同的循环嵌套内，更换位置，自然会不同，这很正常。

第二.
什么叫 daltA1 没有算进去？我不知道你希望怎么算。
关于计算结果不符合预期，别人往往帮不了你，因为别人不知道你的“预期”。所以，学会 Debug 调试是关键。
