Hi,

 

Takeing an std::string as input, I need to return the same string with any
characters not in the ranges "az", "AZ" and "09" being discarded. A
colleague told me that a could use something in the string algorithm
library, but I'm obviously not spotting what I need. I tried regex replace,
but failed, as I'm not understanding regular expressions yet.

 

Any and all suggestions would be gratefully received.

 

Best wishes.
