How do you make a program in C where the strings are non-case sensitive?

just like the title i would like to create a program in C where when you compare strings it is non-case sensitive...

How do you make a program in C where the strings are non-case sensitive?
cstrings (char*) will always be case sensitive because you are just storing an array of character length data.





You can however do a case insentive comparison by calling stricmp instead of strcmp.





If your using linux the function is strcasecmp() .





Remember if you want avoid memory leaks use the strn version (strnicmp) and specify a length.

Reply:Create two temp strings: str1 and str2, convert both strings into lower/upper case and compare (strcamp) them will do.
Reply:Well, to be honest, I am not a C developer, but I can tell you that in other languages, such as C#, Java, and VB, I was taught to convert the strings to be compared to all upper or all lower cases before comparing them. I am not sure if there is a similar conversion type function built into C or not, but if there is, that is how I would do it. Good luck.
Reply:You can use the standard C functions stricmp() and strnicmp(), or you could convert CStrings to a uniform case using the MakeUpper() or MakeLower() member functions. But this can be a problem if the original case of the CString objects needs preserving.





A couple of examples:





1. If you were searching for strings:





BOOL CMyClass::FindNoCase(CString sS1, CString sS2)


{


// Search a string for another string


// irrespective of case.








CString sToBeSearched = sS1;


sToBeSearched.MakeLower();





CString sFindThis = sS2;


sFindThis.MakeLower();





if(sToBeSearched.Find(sFindThis) != -1)


return TRUE;


else


return FALSE;





}








2. If you just wanted to do a direct comparison:





BOOL CMyClass::EqualsNoCase(CString sS1, CString sS2)


{


// compare strings


// irrespective of case





CString sFirst = sS1;


sFirst.MakeLower();





CString sSecond = sS2;


sSecond.MakeLower();





if(sFirst == sSecond)


return TRUE;


else


return FALSE;





}
