Good to know a simple and non-boost-dependency version. String library has a lot of algorithms for doing case-insenstive comparisons and so on. The details are on Guru of The Week number Thank you. You might be spreading security…. If the locale is not POSIX, the results are undefined so it might do a localized compare, or it might not. Just a note on whatever method you finally choose, if that method happens to include the use of strcmp that some answers suggest:.

book for students and as a holistic reference manual for professionals. The C++ C++ supports efficient software development on the lines of the top-down principle. If The standard functions of the C language, such as strlen(), strcpy(), strcmp(). copied to the next free array element and the counter is incremented.

unresolved external symbol _strncasecmp.
However, you should examine your compiler's documentation to see C++ compiler is free to exceed one or more of these minimums, and The strcmp() function compares two strings and returns 0 if they are equal.
Just a note on whatever method you finally choose, if that method happens to include the use of strcmp that some answers suggest:.
How would the single function template invoke either toupper or towupper without resorting to use of specialization or macros, a function overload seems like a simpler and more appropriate implementation than either.

|This is not a very efficient solution - you make copies of both strings and transform all of them even if the first character is different.

Thank you. One thing that hasn't been mentioned so far is that if you are using stl strings with these methods, it's useful to first compare the length of the two strings, since this information is already available to you in the string class.
Since determining the length of a string consists of iterating over every character in the string and comparing it against 0, is there really that much difference between that and just comparing the strings right away? Actually, the boost string library is a header only library, so there is no need to link to anything.
