Well you can use the "toupper" or "tolower" functions from the cctype library to convert all the letters in the string to upper or lower case one character at a time, then do whatever string comparison you want to do.

We won't write code for you (its in the rules), however I suggest that you follow VernonDozier's advice and loop through all elements in the string, set the charactors to lower or uppercase, then compare the results. smile.gif

or you just use the stdlib function "stricmp" in conjunction with basic_string::c_str()

There is no such function as stricmp anywhere in standard C or C++. The only way to do this in standard C++ is to roll your own.

There is a function known as strcmp and one known as strncmp in C++ and it is under the string header file

I think his point was that the mentioned stricmp() function is not part of the standard library - not the the other 2 did not exist.

No offense taken sir - I merely mentioned it because the thread deals with case insensitive string comparisons, and neither strcmp() nor strncmp provide this functionality. I had assumed that the original poster new about the standard functions, but had not mentioned them since they in no way provide him/her with a soltuion.
