Chapter 6.2, Problem 9SC

Explanation of Solution

Given program:

//Definition of class "Program"

public class program

{

    //Definition of class main

    public static void main(String[] args)

    {

//initialize variable n

        int n = 1;

//while loop executes

while( n ! = 50)

        {

            //print the statement

            System.out.println(n);

            //define variable n

            n = n + 10;

        }

    }

}

Hand-tracing above code:

• In the above code, there is only one variable “n”.
• First this variable is initialized as 1.
• Since “n” is not equal to 50, “while” loop executes and the output value is printed as 1. The value of “n” is incremented by 10.
• Now the value of “n” becomes 11.
• Since the value of “n” is not equal to 50, so “while” loop executes and the output value is printed as 11. The value of “n” is incremented by 10.
• Now the value of “n” becomes 21.
• Since the value of “n” is not equal to 50, so “while” loop executes and the output value is printed as 21...
