Average Until Zero

Read whole numbers one per line until a 0 arrives (the 0 is a sentinel and is not counted), keeping a total and a count with a while loop. After the loop print the average to two decimals in the form Average: <value> using :0.2f; if no numbers came before the 0 print No numbers instead. Input: several lines, each an integer, the last one 0, no prompts.

Expected Output:

Average: 20.00↵

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