import java.util.Scanner;
public class num1 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter User name 1 and 2");
int userNum1 = in.nextInt();
int userNum2= in.nextInt();
if(userNum1<0){
System.out.println("userNum1 is negative.");
}
else if(userNum2>8){
userNum2 =0;
}
else{
System.out.println("userNum2 is less than or equal to 8..");
}
}
}
Explanation:
This is implemented in Java programming language
Using the scanner class, the user is prompted to enter two numbers
These are saved in the variable userNum1 and userNum2 respectively.
If, else if and else statements are then used according to the specifications given in the question.

cout<<"Enter the miles"<<endl;
cin>>miles;//taking input of the miles..
miles_to_km(miles);//calling function that converts miles to km..
cout<<"The number of km is "<<miles<<endl;//printing the km.
return 0;
}
