9. Relational Operators are Tricky



Answer:
    count is 1
count is 2
count is 3
Done with the loop
This is the same as in the first version of the program fragment, but now done differently.

Here is the program fragment:
int count = 1;  
while ( count < 4 )  // there are changes here
{
  System.out.println( "count is:" + count );
  count = count + 1;   
}
System.out.println( "Done with the loop" );      
The relational operator is different from before (now it is <, previously it was <=) and it tests with 4 (previously with 3.) You can figure out what this loop does by observing
      • count starts out at 1.
      • The last value that will test true in the condition is 3.
      • count increases by 1 each time.
so the values that are printed out must be: 1, 2, and 3.
The limit value of 4 is coordinated with the relational operator < to control the loop. Here is another change to the program:
int count = 0;  
int limit = 5;
while ( count <  limit )           // there are changes here
{
  System.out.println( "count is:" + count );
  count = count + 1;   
}
System.out.println( "Done with the loop" );      



Question 9:
What does the above program print?
