+1. What is the difference between an interpreter and a compiler?
+Interpreters are Just-in-time compilers that do not make binaries.  They can be edited like editing a script.  Where as a compiler makes binaries that can't be changed without changing the source code and recompiling.
+
+2. How do you compile the source code with your compiler?
+I create a Makefile - that runs the command ```g++ -o PROJECT main.cpp``` creating a binary with the PROJECT name.
+
+3. What does the linker do?
+The linker uses the local system libraries (Nix, Windows) to make system calls to the CPU.
+
+4. What are the steps in the normal development cycle?
+a) brainstorm
+b) roadmap
+c) code
+d) debug
+e) publish

+Quiz
+1. What is an expression?
+
+2. Is x = 5 + 7 an expression? What is its value?
+
+3. What is the value of 201 / 4?
+Depends on the datatype.  If its an INT it would be 50. float would have the decimal. etc...
+4. What is the value of 201 % 4?
+0 because there would be a remainder so its not perfectly divisble
+5. If myAge, a, and b are all int variables, what are their values after
+myAge = 39;
+a = myAge++;
+b = ++myAge;
+
+6. What is the value of 8+2*3?
+14 - follows pemdas?
+7. What is the difference between if(x = 3) and if(x == 3)?
+
+Around page 80
+
+
+8. Do the following values evaluate true or false?
+a. 0
+b. 1
+c. –1
+d. x = 0
+e. x == 0 // assume that x has the value of 0
+
+------------------------------------------------
+Exercises
+1. Write a single if statement that examines two integer variables and changes the
+larger to the smaller, using only one else clause.
+
+2. Examine the following program. Imagine entering three numbers, and write what
+output you expect.
+
+#include <iostream>
+using namespace std;
+int main()
