Lookup tables in C++ -


I have to implement small multimage graphic controls, which in essence has an array of 9 pictures, which were shown one after the other. is. The final goal is to act as a minislider

Now, this graphic control is going to get different integer ranges: 5 to 25 or 0 to 7 or 9-9 to 9

If I am going to use proportion - "rule of all three" I am afraid it is not technically latent because it can be a source of errors. My guess is to use some lookup tables, but Is there any good advice for the approach?

Thnx

I'm not sure the tables are required to see From your input value, you can get the image indices between 0 to 9 proportionally: 

  int ConvertToImageArrayIndex (int inputValue) {int maxInputFromOtherModule = 25; Int minInputFromOtherModule = 5; // +1 is required so that the potential limit includes both the minimum and maximum input value // 0.5, therefore, round on the closest image instead of the goal always. // 8.0 needs to get an output range of 9 potential indices [0..8] Int image index = ((float) ((input-value-mininputfomother module) * 8.0) / (float) (maximal inputfomass module - Mininputfo audio Module + 1)) + 0.5; Return image index; }

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
