Property Value

Description
html markup
shown to student

Complete the function that receives a string, <tt>word</tt>, and, if the string ends with
an <tt>!</tt> character, return a newly formed string that adds another <tt>!</tt> to the end.

Note: Recall that C++ strings allow use of the <tt>+</tt> operator to perform concatenation.
For example: If the parameter is <tt>Yes</tt> then you should just return:

<pre>
Yes
</pre>

If the parameter is <tt>No!</tt> then you should return:

<pre>
No!!
</pre>

If the parameter is <tt>Wow!!</tt> then you should return:

<pre>
Wow!!!
</pre>

But if the exclamation marks are not at the end, do not alter anything

For example: If the parameter is <tt>What!?</tt> then you should just return:

<pre>
What!?
</pre>

C++ test suite
json list of stdin/args tests
e.g. [{"stdin":"hi", "args":["4", "5"]}, {"stdin":"noargs"}]
to just run once with no input use [{}]

[

{"stdin": "No!"},
{"stdin": "Wow!!"},
{"stdin": "What!?"}
