Exercise to help with dice program:

1) Simple totalling: Keep changing this program by adding each step:

► Write a program to display the numbers between 2 and 40 counting by 2's. You will see:

2

4

up to 40

► Change that to print the total after each number. Print "The total including the last number is " and the total.You will see.

2

the total including the last number is 4

4

the total including the last number is 6

6

the total including the last number is 10

up to 40

► Change that to print the total of all the numbers between 2 and 40 couting by 2's. Label the total : final total. You will see

2

the total including the last number is 4

4

the total including the last number is 6

6

the total including the last number is 10

up to 40

the final total is xxxx

► Change that to not print the running total:

2

4

6

up to 40

the final total is xxxx

► Change that to do the same thing counting backwards.

40

38

upt to 40

the final total is xxxx

2) Dice program: Keep changing this program by adding each step:

► Write this program that displays the number 5 100 times.

int numberIwant;

for (int count = 1; count <= 100; count++)

{

numberIwant = 5;

System.out.println("The number is " + numberIwant);

}

► Accumulate a total, and at the end, print the final total. Print "The final total of added 5s is " and the total. You will see:

The number is 5

The number is 5

printed 100 times

The total is xxxx

► Change your loop to only add the number 5 2 times. Leave everything else the same. You will now see:

The number is 5

The number is 5

The total of added 5s is 10

► Run the 5 2 times loop 20 times. You want it to repeat the following

The number is 5

The number is 5

The total of added 5s is 10

The number is 5

The number is 5

The total of added 5s is 10

(repeat for 20 times)

► Change the number is 5 to the dice throw logic, and accumulate the dice throw instead of the numberIwant.

► Change the number of dice being rolled to 5 instead of 2.
