The given programs are written in Java.
1. WAJP to check whether a number is an armstrong number or not.
import java.util.*;
public class ArmStrong {
public static void main(String args[]) {
Scanner sc=new Scanner(System.in);
System.out.print("Enter a number: ");
int a=sc.nextInt(),b=0,c,d;
c=a;
while(c!=0) {
d=c%10;
b+=d*d*d;
c/=10;
}
if(a==b)
System.out.println("Armstrong number.");
else
System.out.println("Not an armstrong number.");
sc.close();
}
}
2. WAJP to name n number of inputs and check that the number is positive or negative.
import java.util.*;
public class Inputs {
public static void main(String args[]) {
Scanner sc=new Scanner(System.in);
while (true) {
System.out.print("Enter a number:");
int a=sc.nextInt();
if(a>0)
System.out.println("Number is positive.");
else if(a<0)
System.out.println("Number is negative.");
else
break;
}
}
}
