Question

Consider the code below. How many times the value of x is printed? (In other words, how many times the loop is executed?)

public static void main(String args[]) {

      int x = 20;

      while( x > 10 ) {

         System.out.println( x );

         x--;

      }

   }

Consider the code below. What needs to be placed instead of ??? so that loop is run exactly 7 times?

public static void main(String args[]) {

      int x = 7;

      while( x > ??? ) {

         System.out.println( x );

         x--;

      }

   }

Consider the code below. How many times loop is executed?

public static void main(String args[]) {

      int x = 0;

      while( x <= 10 ) {

         System.out.println( x );

         x= x+2;

      }

   }

Answer 1

Consider the code below. How many times the value of x is printed? (In other words, how many times the loop is executed?)

public static void main(String args[]) {

      int x = 20;

      while( x > 10 ) {

         System.out.println( x );

         x--;

      }

   }

Solutions :9 times loop will execute.

Consider the code below. What needs to be placed instead of ??? so that loop is run exactly 7 times?

public static void main(String args[]) {

      int x = 7;

      while( x > ??? ) {

         System.out.println( x );

         x--;

      }

   }

Solution : 8 is replaced with ???

Consider the code below. How many times the value of x is printed?

(In other words, how many times the loop is executed?)

      int x = 0;

      while( x <= 10 ) {

         System.out.println( x );

         x= x+2;

      }

   }

Solution: 5 times

Consider the code below. How many times loop is executed?

public static void main(String args[]) {

      int x = 10;

      while( x <= 20 ) {

         System.out.println( x );

         x= x+3;

      }

   }

Solution: 3times

Consider the code below. How many times the value of x is printed? (In other words, how many times the loop is executed?)
