Here is almost the same loop as in the previous example, but now the control variable is incremented by THREE.

        
The expression count += 3 adds 3 to the value of count .

        

    


System.out.println( "\nDone with the loop.\nCount is now" + count);



    

        

            
int count;

for ( count = 0; count <= 12; count += 3 )  
{
  System.out.println( "count is: " + count ); 
}

        

    

    
Here is a version of this loop. Try to predict the output before you run the program. (Notice that the test is now 
    <= ). (Also, pay careful attention to the value 
        count has just outside the loop.

            

                

                    

                    


     


            




            
Question 8:
Now complete the for statement for each of the following sequences
start at 0, count upward by 1's, end at 7
for ( count = ; count < ; count++ )
start at 0, count upward by 2's, end at 14
for ( count = ; count < ; count += 2 )
start at 1, count upward by 2's, end at 15
for ( count = ; count < ; count += 2 )
