Where is the data written that such and such a variable is a constant?

Question

C++ / C#

For example, we have code:

const int i = 5;
const string g = "6";

Where is it shown in memory or marked in metadata that these variables are constants? How is it labeled under the hood?

Answer 1

You already asked: Where in an instance of a primitive reference type, such as string, is the information that this instance is a constant?
when the code is already compiled, it is not stored anywhere. we just have the values.
during compilation - it is stored like this https : //github.com/dotnet/roslyn/blob/7a836c8e5a06... /7a836c8e5a06... But again, this is only necessary for the compiler to know what to do with these values. As a result, the values ​​of the constants will be substituted for all places of use (which you can easily verify by decompiling the code)
