发帖数: 6411 | 1 what is the best way to compare string ignore case? I did not find an
method in the string class doing that, do I still need to use c to convert
the character to all lowercase or uppercase? |

The fastest (not necessarily the best) way is to set up a look up table T
such that T[uppercase(char)] = T[lowercase(char)]. |

C++ and C both have a version of tolower, do not mix them.
most likely, you will need a template to wrap it if you have to include
stdio.h in C++. |
