These questions are apart of a review for a test I am going to take tonight, so it is not for a homework assignment/test but for me to understand some concepts that will be on the test. So here are my questions:
If I were to draw the following picture using only one cout statement how would you do so:
My major problem with this question is how do I output quotations?
Also, why are functions an important part of C++ programming?
Lastly, what is the difference between value and reference parameters?
The escape character \ allows you to user special characters in strings. For example, I would draw your face like this:
string face = "\"\"\"\"\no-o\n^\n\\_/";
cout << face;
As with any other language, functions are important because they facilitate modularity.
Think of a variable as a box with a ball inside of it. When you pass this variable to a function by value, you're passing the ball. When you pass it by reference, you're passing the box (with the ball in it).
