Install msys2-x86_64-20240727.exe (use the default path, which is on C:…).

Install w64devkit-x64-2.0.0.exe (change path to C:, it will add w64devkit folder.)

Data Structure Alignment 数据结构对齐 #

x86-64 architecture #

Overall rule: any data structure/element should be accessed by CPU with minimum CPU cycles. A 32bit CPU can access 4Bytes in one cycle, while a 64bit one can access 8Bytes. When a memory access is not aligned, it is said to be misaligned (wiki).
Thus, there are two practical rules for us to understand compiler’s padding:

Rule 1: any basic data structure/element/variable should be aligned so that their beginning address is divisible (任何变量的开始地址都能被自己的大小整除，即：当被访问的数据长度为 n 字节时，数据地址为 n 字节对齐。).

Comparison of Programming Fonts - Fantasque vs Dejavu vs Mononoki vs Inconsolata

Before comparison, we need to know that the following sizes are roughly the same: dejavu09 vs mononoki10 vs inconsolata10

Dejavu #

If you are looking at this page, you know coding.
If you know coding, you should know Dejavu.
Thus, I will skip the intro for it.

Mononoki #

• looks similar like dejavu, but its punctuation is much bigger and easier to see. // may draw mroe attention than code ???
• mononoki10 is the same size of dejavu09, but mononoki11 is longer than dejavu10.
• trying to use all space, thus, even mononoki10 is the same size of dejavu09, it is a slightly bigger.
• some minor differences: digits 0 & 1, char g.
• the punctuation symbols may touch each other, but the charaters never touch each other, which is a reversed situation compared wit dejavu.
