如何把C工程转成C++工程

Question

我有一个包含50+ .c 和 20+ .h 的c工程，需要转成c++类以便在单个exe中产生多个实例

是否有通用的指导方法

我google了一下，想到下面几点

1. 把.c 改为 .cpp 解决所有隐式转换的错误

2. 删除static修饰，处理全局名字冲突

3. 创建一个全局.h 文件，新建一个FOO类，把所有的全局函数，变量放入这个类

4. 原先保存宏和常数的头文件以 extern "C"方式 include

5. 所有的函数重命名为FOO::函数

Answer 1

Write a C++ class file to encapsulate the C code

Answer 2

I have seen many projects where C++ calls C库. They all
compile C库 using C编译器 into library,
and then C++ code using the extern "C" methodincludeInterface,
then write a class to encapsulate the interface you use,
and finally link to library.

This will be easier and the correctness is guaranteed. If you change C to C++ source code, the workload will be too much and you will have to retest
