Sum of Digits (while)

The variable n holds 1234. Use a while loop to add up its digits (1 + 2 + 3 + 4) and print the output shown in Expected Output.

Use n % 10 to grab the last digit and n /= 10 to remove it.

Expected Output:

Sum of digits: 10↵

= newline. The output ends with a newline — print one after the last line.
