3. Place Values

by CodeChum Admin

Manipulating values from a series of numbers is fun, but let's try exploring the use of loops a little more.

How about printing out each digit of a number by place values, in ascending order?

Instructions:

1. Create a variable and input a random positive integer.
2. Using while loop, print out each digit of the inputted integer in separate lines, starting from its rightmost digit until the leftmost digit of the number. Tip: Use % 10 to get the rightmost digit, and / 10 to remove it from the number.
3. Another tip: don't forget to consider the case wherein the input is `0`

Input

A line containing an integer.

214

Output

Multiple lines containing an integer.

4. Gathering Positivity

by CodeChum Admin

I always want to look at the positive side of things, so I decide to seriously look at positive numbers, too!

Will you code along with me?

Instructions:

1. Using the do…while() loop, continuously scan for random integers, but add up only all the positive integers and store the total in one variable.
2. The loop shall only be terminated when the inputted integer is zero. Afterwards, print out the total of all inputted positive integers.

Input

Multiple lines containing an integer on each.

5. "Even" Now

by CodeChum Admin

I'm really fond of even numbers, you know? That's why I'll be letting you make another even number problem yet again. This time, you need to print from a range of two inputted numbers, n1 and n2 (inclusive), all the even numbers from n2 down to n1, in descending order.

How about that?

Input

A line containing two integers separated by a space.

3·10

Output

Multiple lines containing an integer.
