uppercase

In one of my interview, the interviewer asked me why the upper case letters are before the lower case letters in ASCII table, I searched on google.com but found nothing, could anyone gave me the answer? Thx a lot! I'm only guessing, but I imagine it's because the earliest character sets had no lowercase at all. The Baudot telegraph code was only 5 bits, and CDC mainframes natively used a 6-bit code; there was no room for lowercase. When ASCII was developed as a 7-bit code which finally had enough room for lowercase letters, they were considered something of a luxury add-on, so it made sense to

int main() { string s; cout << "enter the string :" << endl; cin >> s; for (int i = 0; i < s.length(); i++) s[i] ^= 32; cout << "modified string is : " << s << endl; return 0; } I saw this code which converts uppercase to lowercase on stackoverflow. But I don't understand the line s[i] = s[i]^32 . How does it work? ^= is the exclusive-or assignment operator. 32 is 100000 in binary, so ^= 32 switches the fifth bit in the destination. In ASCII, lower and upper case letters are 32 positions apart, so this converts lower to upper case, and also the other way. But it only works for ASCII, not for

I am currently using CSS to change everything I write to upperCase when I create an entry, but that is not enough. When I save things, the text shown in the text fields is upper case, but the real value that Grails stores stays in lower case. I am assuming I'd need to change something in the controller or anything. Maybe transforming the $fieldValue CSS could work?? Any ideas would help! Thnks! You could just write setters for your domain object? class Domain { String aField void setAField( String s ){ aField = s?.toUpperCase() } } I think you are asking how to change values on your domain

I am wondering that why Character.toUpperCase/toLowerCase has no Locale parameter like String.toUpperCase/toLowerCase . I have to first uppercase of a text that can be in Any language. I have 2 solutions: Use Character.toUpperCase String text = "stack overflow"; StringBuilder sb = new StringBuilder(text); sb.setCharAt(0, Character.toUpperCase(sb.charAt(0))); // No Locale parameter here. String out = sb.toString(); //Out: Stack overflow Use String.toUpperCase Locale myLocale = new Locale(locateId); String text = "stack overflow"; String text1 = text.substring(0,1).toUpperCase(myLocale ); String

The issue I came across has to do with the capitalization of Greek characters by the text-transform: uppercase property. In Greek, vowels can have acute accents, both small and caps, for instance one in Greek is ένα . In the beginning of a sentence would be Ένα . But when a word or a phrase is written in all caps then Greek grammar says that it should have no accented letters . As it is now, CSS's text-transform: uppercase capitalizes Greek letters preserving accents which is grammatically wrong (so ένα becomes ΈΝΑ , while it should be ΕΝΑ ). How do I make text-transform: uppercase work

I have this C code. If I input a LOL123 it should display that it is uppercase. And lol123 it is in lowercase. How do I use isalpha in excluding non-numerical input when checking isupper or is lower? #include <stdio.h> #define SIZE 6 char input[50]; int my_isupper(char string[]); int main(){ char input[] = "LOL123"; int m; m= isupper(input); if( m==1){ printf("%s is all uppercase.\n", input); }else printf("%s is not all uppercase.\n", input); return 0; } int my_isupper(char string[]){ int a,d; for (a=0; a<SIZE); a++){ d= isupper(string[a]) ; } if(d != 0) d=1; return d; } For upper-case

I have this kind of input word w'ord wo'rd I need to convert to uppercase both characters at the starts of the word and right after the ' character (which can exists multiple times). The output I need (using the previous example) is word W'Ord Wo'Rd I tried with a simple pattern s.replaceAll("(\\w)(\\w*)'(\\w)", "$1"); but I'm unable to convert the group 1 and 3 to uppercase EDIT: After I discovered a little mistake in the main question, I edited @Wiktor Stribizew code in order to include the case I missed. Matcher m = Pattern.compile("(\\w)(\\w*)'(\\w)").matcher(s); StringBuffer result = new
