Loops and the While Statement

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.

Relational Operators are Tricky

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?
