/*Below is a beginner C++ program assignment I wrote to calculate volume using functions. I cannot quite get it to run. Can you please help. I was having trouble with printing strings. Then I included , but now i am gettig error message: " local variable choiceChar undefined." can you paste this code into your visual studio and try to run it and trouble shoot it for me. Also, it is saying that it cannot find the file. Thank you. */
