# Convert String To Camelcase ## Write a program to convert string to camelcase Camelcase is a style of writing in which the first letter of each word is capitalized except the first word. ```txt Input : "hello world" Output : "helloWorld" ``` --- ```c #include #include int main() { char str[100],camelcase[100]; int flag=0,i=0,j=0; printf("Enter a sentence\n"); gets(str); printf("Original String = %s\n",str); while(str[i]!='\0') { if(str[i]==' ') { i++; flag=1; continue; } if(flag==1) { camelcase[j]=str[i]-32; flag=0; } else { camelcase[j]=str[i]; } j++; i++; } printf("Camel Case = %s",camelcase); return 0; } ``` ```cpp #include using namespace std; int main(){ string s; getline(cin, s); int ind = 0; for (int i = 0; i < s.length(); i++){ if (s[i] == ' '){ s[i + 1] = toupper(s[i + 1]); continue; } else s[ind++] = s[i]; } cout << s.substr(0, ind) << endl; return 0; } ``` ```csharp using System; class CamelCase { static void convert(String s) { int cnt= 0; int n = s.Length; char []ch = s.ToCharArray(); int res_ind = 0; for (int i = 0; i < n; i++) { if (ch[i] == ' ') { cnt++; ch[i + 1] = char.ToUpper(ch[i + 1]); continue; } else ch[res_ind++] = ch[i]; } for(int i = 0; i < n - cnt; i++) Console.Write(ch[i]); } public static void Main(String []args) { String str = "hello world"; convert(str); } } ``` ```java import java.util.Scanner; public class ConvertStringToCamelCase { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Input: "); String input = scanner.nextLine(); String[] inputArray = input.split(" "); StringBuilder output = new StringBuilder(); for(int i = 0; i < inputArray.length; i++) { if(i == 0) { output.append(inputArray[i]); } else { output.append(String.valueOf(inputArray[i].charAt(0)).toUpperCase()).append(inputArray[i].substring(1)); } } System.out.println("Output: " + output); } } ``` ```javascript function convertStringToCamelCase(str) { var splitVal = str.split(" "); for (var i = 1; i < splitVal.length; i++) { splitVal[i] = splitVal[i].substr(0, 1).toUpperCase() + splitVal[i].substr(1); } return splitVal.join(""); } console.log(convertStringToCamelCase("hello world")); ``` ```kotlin import java.util.Scanner fun main() { print("Enter String : ") println() var min = readLine() println("Camel Case: " + CamelCase(min!!.split(" "))) } private fun CamelCase(args: List): String { val buffer = StringBuffer() for((index,day) in args.withIndex()){ //println("$index :$day") if(index == 0) { buffer.append(day); } else { buffer.append(day.get(0).uppercase()).append(day.subSequence(1,day.length)) } } return buffer.toString() } ``` ```ruby puts 'Please, insert your string: ' user_input = gets.chomp result = user_input.split(' ').map(&:capitalize).join result[0] = result[0].downcase puts result ``` ```typescript function stringToCamelcase(str: string): string { let i: number = 0; const splitstr: string[] = str.split(""); while (i < splitstr.length) { if (splitstr[i] === " ") { splitstr.splice(i, 1); splitstr[i] = splitstr[i].toUpperCase(); } i++; } return splitstr.join(""); } const str: string = "hello world"; console.log(stringToCamelcase(str)); // "helloWorld" ``` ```julia println("Enter a string: ") sub = split(readline(), " ") n = length(sub) s = sub[1] for i in 2:n global s = s * titlecase(sub[i]) end println("Given string in camelcase: ", s) ``` ```go package main import ( "fmt" "strings" ) func camelcase(str string) string { words := strings.Split(str, " ") new_words := []string{} i := 0 for _, word := range words { if len(word) > 1 && i > 0 { new_words = append(new_words, strings.ToUpper(word[0:1])+(word[1:])) } else { new_words = append(new_words, word) } i++ } return strings.Join(new_words, "") } func main() { str := "hello coders" fmt.Println(camelcase(str)) } ``` ```php ``` ```perl my $str = 'hello world'; $_ = $str; $_ = lc; s/(?<=[^\W_]) +([^\W_])|_+/\U$1/g; print; ``` ```python from re import sub a = input() # the below line removes _ or - with " ", then each word's first letter is made capital, # and finally we proceed with replacing " " with "" a = sub("r[_|-]", " ", a).title().replace(" ", "") print("".join([a[0].lower(), a[1:]])) ```
