Compilation process description

Compile Parameters	File Size	File Name	Execution time
/Optimize	3,584 bytes	Calcpi.exe	8937.5 Ms
/Filealign: 512	3,584 bytes	Calcpi512.exe	8843.75 Ms
/Filealign: 1024	5,120 bytes	Calcpi1024.exe	9031.25 Ms
/Filealign: 8192	32,768 bytes	Calcpi8192.exe	8843.75 Ms

You can see that using the/filealign parameter and bringing a small value (must be a multiple of 512) can reduce the size of the generated file moderately, without affecting execution efficiency. Another problem is that I used optimization but didn't improve the program efficiency. I don't know why.
The following are:
