删除“const"是否更好?在“原始"前面在标头中用作函数参数的类型?

In the code review process, one of my coworkers mentioned to me that "const"s in front of "primitive types" used as a function parameter in a header is meaningless, and he recommended to remove these "const"s. He suggested using "const" only in the source file in such cases. Primitive types mean types such as "int", "char", "float", etc.

以下是示例.

example.h

int ProcessScore(const int score);

example.cc

int ProcessScore(const int score) {
  // Do some calculation using score
  return some_value;
}

他的建议如下:

example.h

int ProcessScore(int score);  // const is removed here.

example.cc

int ProcessScore(const int score) {
  // Do some calculation using score
  return some_value;
}

但我有点困惑.通常情况下，用户只会看头文件，所以如果头文件和源文件不一致，可能会造成混淆.

void foo(int const i, int const j);
void foo(int i, int const j);
void foo(int const i, int j);
void foo(int i, int j);
