A. Write a program that asks the user to enter an integer, then prints a list of all positive integers that divide that number e
kobusy [5.1K]

Answer:

Following are the program in python language the name of the program is factors.py

num= int(input("Please enter a positive integer: "))#Read the number by user

print("The factors of ",num,"are:")

for k in range(2,num): #iterating over the loop

   if(num%k==0): #checking the condition

       print(k)#display the factor

Output:

Please enter a positive integer: 12

The factors of 12 are:

2

3

4

6      

Explanation:

Following are the description of the program

  • Read the number by user in the "num" variable
  • Iterating the for loop from k=2 to less then "num".
  • In the for loop checking the factor of "num"  variable by using % operator.
  • Finally display the factor by using print function

Just a quick question, how do you set something == to char and int in an if statement (java)
Troyanec [42]

This is the requested code in java.

public class <em>CharTest</em> {

   public static String checkCharacter(String text, int index) {

       if (0 <= index && index <= text.length()) {

           char ch = text.charAt(index);

           if (Character.isLetter(ch)) {

               return ch + " is a letter";

           } else if (Character.isDigit(ch)) {

               return ch + " is a digit";

           } else if (Character.isWhitespace(ch)) {

               return ch + " is a whitespace character";

           } else {

               return ch + " is an unknown type of character";

           }

       } else {

           return "index " + index.toString() + " is out of range";

       } // <em>end if</em>

   } // <em>end function checkChar()</em>

   public static void <em>main</em>(String[] args) {

       // <em>Test the three samples from the specification.</em>

       System.out.println(<em>checkCharacter</em>("happy birthday", 2));

       System.out.println(<em>checkCharacter</em>("happy birthday", 5));

       System.out.println(<em>checkCharacter</em>("happy birthday 2 you", 15));

   } // <em>end function main()</em>

} // <em>end class CharTest</em>

The function <em>checkcharacter</em>(text, index) returns a string value describing the kind of character found at the position in text specified by index; whether it was a letter, digit, whitespace, or an unknown kind of character.

How it does that is to make use of respective functions defined within the Character class in java. That is

  • isLetter(char) returns a bool specifying if the char parameter is a letter.
  • isDigit(char) returns a bool specifying if the char parameter is a digit.
  • isWhitespace(char) returns a bool specifying if the char parameter is a whitespace character.

It calls these functions in an if statement. These else part of the if statement is then executed if the character is neither a <em>letter</em>, <em>digit</em>, or <em>whitespace</em>.

Finally, the function main() calls <em>checkCharacter</em>() three times to test the function and return the results to the console.

Another example of a java program on characters is found in the link below

JAVA
butalik [34]

Answer:

import java.util.*;

public class MyClass {

   public static void main(String args[]) {

       Scanner input = new Scanner(System.in);

       System.out.print("Input a word: ");

       String userinput = input.nextLine();

       for(int i =0;i<userinput.length();i+=2) {

           System.out.print(userinput.charAt(i));

       }

   }

}

Explanation:

This line prompts user for input

       System.out.print("Input a word: ");

This declares a string variable named userinput and also gets input from the user

       String userinput = input.nextLine();

The following iterates through every other character of userinput from the first using iteration variable i and i is incremented by 2

       for(int i =0;i<userinput.length();i+=2) {

This prints characters at i-th position

           System.out.print(userinput.charAt(i));
