程式命名规则 与 Makefile
1. 查阅了 ISO 1999 C99, ISO 2011 C++, ISO 2014 C++, ISO 2020 C++,
https://reurl.cc/gZGz6L
https://reurl.cc/XLGlq0
ISO都有基本的命名规则
另查阅 微软 安卓 程式规范
微软 的 命名规则偏向 The Hungarian Naming Convention
由2001 制定完整规范, prefix 如ch, sz, p
https://idleloop.com/hungarian/
2. variable prefix naming convention 一定是正确的吗?

Page 12 原文贴上
Do not use Hungarian notation
Do not abbreviate
Do not prefix enums, classes, or delegates with any letter
(b)
Linux核心的创始者 开源专案Git创始者 Linus Torvalds

第四章 原文贴上
Encoding the type of a function into the name (so-called Hungarian notation)
is brain damaged - the compiler knows the types anyway and can check those,
and it only confuses the programmer. No wonder MicroSoft makes buggy programs.
(注意一下这两位大神coding在意的重点是什么)
3.
GNU MAKE
https://www.gnu.org/software/make/manual/make.html
#dir named with www.gnu.org/software/make/manual/make.html 4.3 16.3 16.5
SRCDIR = ./source
OBJDIR = ./obj
BINDIR = ./bin
#compile optione with www.gnu.org/software/make/manual/make.html 4.3 16.3 16.5
$(OBJDIR)/%.o : ./$(SRCDIR)/%.cpp
$(CXX) -c $(CXXFLAGS) $< -o $@
#link
$(TARGET): $(OBJFILES)
$(CXX) $^ $(LDFLAGS) -o $(BINDIR)/$@
有人习惯使用
$(CXX) $(LDFLAGS) $^ -o $(BINDIR)/$@
$^ 代表着许多 .o 档
$(LDFLAGS)若放在 $^ 前面
ubuntu 16/18 x86_64 g++ link -lpthread 会找不到
所以 "$(LDFLAGS) 一定要放在 $^ 之后"
#Note: CPPFLAGS at www.gnu.org/software/make/manual/make.html 10.3
CC
Program for compiling C programs; default ‘cc’.
CXX
Program for compiling C++ programs; default ‘g++’.
CPPFLAGS
Extra flags to give to the C preprocessor and programs that use it (the
C and Fortran compilers).
CXXFLAGS
Extra flags to give to the C++ compiler.
※ 引述《heaviest (heaviest)》之铭言：
: 最近开始学C，刚刚把前几天写的程式，打开来看
: 发现变量一时之间完全搞不清楚
: 明明当初有尽力的取有意义的名称，然后照着大写来分开字这样打
: 跑去问了学长，他叫我去背单字，他说变量名字取不出来是我单字被太少QQ
: 请问各位前辈们都怎么取有意义的名字
