How to display as string a member variable in a struct/class when the mouse hovers on variable?

Question

That question was always in my head for a very long time, for examples how to turn:

• type=1 into "one".
• type=2 into "two".
• type=3 into "three".
• Member variable with type vec2 into "{x, y}".
• Member variable with type vec3 into "{x, y, z}".
• Member variable with type vec4 into "{x, y, z, w}".
• etc.

I use VSCode with the compiler from Visual Studio 2015:

Note: I cannot use enum because I downloaded source codes from professional developers and they don't use enum, they just use int.

The reason I don't store the string display in a separate member variable is for performance reason, and the variable can be changed at any time but I can forgot to update the string, it's always better to have simple codes as possible for fast development as possible.

Sorry,
but with your restrictions, it is impossible.
