I'm glad I was able to do the exercise myself before watching. I've been going through a lot of problems lately and I'm not 100% focused, so that was something

[ThePlokonChannel]

Scanner sc = new Scanner(System.in);

System.out.print("Enter a number: ");
Integer n = sc.nextInt();
int sum = 0;

for (int i = 0; i < n.toString().length(); i++) {
String ns = n.toString();
sum +=
}

System.out.println(sum);

thank you so much. you teach me very needful things ❤❤

[kartikrastogi]

using for loop;

import java.util.Scanner;

public class ner {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
int n = scan.nextInt();
int sum = 0;

for (int i =1 ; (n/i)>=1; i = i*10){
sum = sum + ((n/i)%10);
}

System.out.println("sum : "+sum);


}
}

[thivagarmurugan]

public static void main(String args[]) {

Scanner num = new Scanner(System.in);
int n = num.nextInt();
int sum = 0;
while (n != 0) {
int rem = n % 10;
sum += rem;
n = n / 10;

}
System.out.println(sum);

}
}

public class Main {

int n = input.nextInt();
int sum = 0;
while(n > 0){
sum += n % 10;

//using while loop that is much easier to understand + choices

import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner input = new Scanner(System.in);

int n;
int sum;
int answer;

while (true) {
System.out.println("enter a number ");
n = input.nextInt();
int x = n % 10;
int y = n / 10 % 10;
int z = n / 100;
sum = x + y + z;

System.out.println("SUM: " + sum);
System.out.println("do you want to enter another number? 1 if yes and 2 if no");
answer = input.nextInt();
if (answer == 2)
break;
}

System.out.println("done");
}
}

import java.util.*;

Where is DATA STRUCTURE using C language?
I am waiting from a long time sir.

[DilpreetSingh-pdco]

i did it by
// TODO code application logic here

System.out.println("enter number");

Scanner sc=new Scanner(System.in);

int a=sc.nextInt();
int add=0;

for(int
{
char
String cts=String.valueOf(index);

int index1=Integer.valueOf(cts);
add+=index1;

}


System.out.println(add);


}

int sum = 0;
int divisor = 1;
System.out.println("enter the digitS to find the sum of");
int numb = input.nextInt();
String numberString = Integer.toString(numb);
int length = numberString.length();
for(int i = 1; i <= length; i++){
sum += ((numb/divisor)%10);
divisor *= 10;


}
System.out.println("sum of the numbers are: " + sum);

/*while (input > 0) {

input = input / 10;
}
System.out.print(result);*/

Please clarify why we divide by 10 and as well use 10 for the modulo operation? What if u choose a different number ? Thank u 🙏🏾

[navedrahman]

What happens if user writes 000? and can you explain you n>0
