tolower function for C++ strings -


Is there a built-in function for converting C ++ strings from upper case letters to lowercase letters? If it is not converted to seestring and is the only option to use a toller on each variable?

Thank you very much earlier.

If boost is an option: 

 < Code> #include & lt; Boost / algorithm / string.hpp & gt; Std :: string str = "wHatEver"; Promote: to_lower (STR);

Otherwise, you can use std :: transform : 

  std :: string str = "wHatEver" ; Std :: conversion (str.begin (), str.end (), str.begin (), :: tolower);

If you have some custom locale-aware tolower you can also use another function.

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....
