Construct an example of a call to a pre-defined C++ function.
Your C++ code should include any necessary libraries, declare any variables used in the function call, and list the function call itself. You do NOT need to write an entire program.
After the code, include an English explanation of what your chosen function does, and what the result of your function call would be.
Warning: Please ensure that your example has not been previously presented in this course, that it is not related to this week's programming assignments, and that it has not already been posted by another student.
Post your function call example as a REPLY to this message.
