Converting String to Title Case

Converting string to title case

MSDN : TextInfo.ToTitleCase

Make sure that you include: using System.Globalization

string title = "war and peace";

TextInfo textInfo = new CultureInfo("en-US", false).TextInfo;

title = textInfo.ToTitleCase(title); 
Console.WriteLine(title) ; //War And Peace

//When text is ALL UPPERCASE...
title = "WAR AND PEACE" ;

title = textInfo.ToTitleCase(title); 
Console.WriteLine(title) ; //WAR AND PEACE

//You need to call ToLower to make it work
title = textInfo.ToTitleCase(title.ToLower()); 
Console.WriteLine(title) ; //War And Peace

Is there a simple way to convert java string to title case including diacritics, without third party library

I use this method with regex:

public static void main(String[] args) {

    System.out.println(titleCase("JEAN-CLAUDE DUSSE"));
    System.out.println(titleCase("sinéad o'connor"));
    System.out.println(titleCase("émile zola"));
    System.out.println(titleCase("O'mALLey"));
}

public static String titleCase(String text) {

    if (text == null)
        return null;

    Pattern pattern = Pattern.compile("\\b([a-zÀ-ÖØ-öø-ÿ])([\\w]*)");
    Matcher matcher = pattern.matcher(text.toLowerCase());

    StringBuilder buffer = new StringBuilder();

    while (matcher.find())
        matcher.appendReplacement(buffer, matcher.group(1).toUpperCase() + matcher.group(2));

    return matcher.appendTail(buffer).toString();
}

I have tested with your strings.

Here is the results to output:

Jean-Claude Dusse
Sinéad O'Connor
Émile Zola

Javascript - Adjusting string to title case logic

letterToCapitalize finds the first occurrence of [a-zA-Z0-9_] in each word you're trying to capitalize (the first suitable letter of).

In your code, you must remember that .replace(...) actually returns a brand new string. It does not modify the string in place (in JavaScript, primitive data-types, of which strings are one, are not modifiable). The problem was you weren't assigning this new string to a variable that you were logging out.

let title = "Adjusting the title (case and test) on tv"

let titleCase = title.toLowerCase().split(' ').map((s) => {
    let letterToCapitalize = s.match(/\w/)[0];
    return s.replace(letterToCapitalize, letterToCapitalize.toUpperCase())
    }).join(' ');
    
titleCase = titleCase.replace(/and/ig, '&').replace("Tv", "TV");

console.log(titleCase)

How to convert string to Title Case?

In the function the string B is an empty string so there is no B[0], however you can assign a char to a string so the following should work

string Title_Case (const string A){
        
        char First_capital = static_cast<int>(A[0]) - 32;
        string B;
        B = First_capital; 
        
        for ( int i =1; i <A.size(); i++){
                if( A[i-1] == ' ' &&  A[i] >= 'a' && A[i] <= 'z'){
                                char capital = A[i] - ( 'a' - 'A');
                                B += capital;
                                continue;
                        }
                else
                        B = B + A[i];
        }
        
        return B;
}

How to convert string to Title Case in Python?

Why not use title Right from the docs:

>>> "they're bill's friends from the UK".title()
"They'Re Bill'S Friends From The Uk"

If you really wanted PascalCase you can use this:

>>> ''.join(x for x in 'make IT pascal CaSe'.title() if not x.isspace())
'MakeItPascalCase'

Convert string to title case with exceptions for articles (a, an, the..etc)

The Array.includes(String) function returns if the string is a part of the array.

This should work,

for(i = 0; i < splitStr.length; i++) { 
    // Check if our word is a part of the exceptions list
    if(i>0 && exceptions.includes(splitStr[i]))
        // if it's an exception skip the capatilization
        continue;

    splitStr[i] = splitStr[i].charAt(0).toUpperCase() + splitStr[i].substring(1);
}

Credit for i>0 condition goes to @Ringo, i didn't think about that before. He's right that first word should always be capitalized regardless.
