c++ Case Sensitivity

[danielporsh911]

Hey I was just coding in C++ well practicing im not the best at it and I was just wondering on how to check for case sensitivity when crosschecking two strings as like a password check. I want to do it within the clause of an if statement. I couldnt seem to find any information about this on the web.

The method std::string::compare is case sensitive, but if you want a case insensitive comparison just convert them to lower case.

 

// perform a case sensitive comparison

if (str0.compare(str1)==0)

// the strings are equal

What do you mean, “check for case sensitivity?” Strings don’t have a property that defines them as sensitive or insensitive to “casing.” You can use the C library function toupper() or tolower() to convert a string to all uppercase/lowercase and then compare the two insensitively. By default differently cased strings with the same letters will not match.

 

Keep in mind: The C library function I mentioned, as well as the operation @FedeWar mentioned, only works for ASCII strings. So you’ll have to look for a library to handle non-Latin characters.

Oh shit thank you.

To handle non latin characters exits std::wstring, it should work as a normal string.
