尝试编写一段代码，生成一个包含14天随机温度读数的数组。然后输出这14天的最高温、最低温以及平均温度

编程语言 2026-07-12

我正在尝试编写一个代码，用来生成一个包含14天温度读数的随机数组；每天11次读数。然后计算每天的最高/最低温度，以及计算该数组的平均最高/最低温度。我觉得自己在某个循环里卡住了，但不确定具体在哪里。当我运行调试器时，初始化部分工作正常，但其他都不起作用。我折腾过它，通常可以让display Temp array和 display Temp With Strings显示出来，但在计算、数组以及每日最高和最低温度的处理上有很大困难。

解决方案

The printGreeting proc is ok, but to me it seems a bit convoluted with these three arguments. One argument to a single cartouche would be much cleaner.

现在真正的问题在程序的早期就开始出现！

  • For generating the temperatures you invoke generateTemperatures with a single argument, yet you return from it using ret 8. Your stack is already corrupted! (Also what about the incomplete procedure header?)
  • The findDailyHighs and findDailyLows procs are very similar, and indeed you copy-pasted here and left some redundant instructions while doing so! Several things got wrong:
  • You got source and destination reversed. The offset to the temperature array was pushed last, so that resides at [ebp+8] and must go to ESI.
  • The inner loop is set to perform one iteration too many. With 11 items there can be but 10 comparisons.
  • The inner loop can not be using the loop instruction. It is meant to use EBX instead (dec ebx jnz _inner)
  • The displayTempArray and displayTempWithStrings procs got lots of arguments (8 and 4) but both return through a naked ret. This leaves the arguments on the stack!
  • It's been a long time I looked at irvine's but does writeInt really expect EDX for its argument? Shouldn't it be EAX?
  • The name displayTempArray clearly suggests processing the full array, yet you haven't written a loop that iterates over the array's elements. A work in progress no doubt?

最后还有那个孤立的proc calAverageLowHighTemps。它从无处调用，目前这还好，因为它在（重复两遍的）指令对 loop _cal... div ecx 中包含了可怕的除法异常。记住在 loop 完成后ECX=0。

你需要一步一步来。你已经有太多未经过测试的代码了！
第一步应该是成功地

  • 打印你的opening cartouche
  • 生成温度数组
  • 打印温度数组

一旦这真的能工作，你再添加一段额外的代码，然后再次运行。等它工作正常后再添加更多。祝你好运！

还有一个额外的错误我忘了提及：

; findDailyLows PUSH OFFSET low_daily PUSH temp_array CALL findDailyLows

看到了吗，这里你省略了 OFFSET 说明符？
该过程预计一个地址，但 push temp_array 只是传递了数组第一个元素的值。
