 =====Reflection=====
-Comments/thoughts generated through performing the project, observations made, analysis rendered, conclusions wrought. What did you learn from doing this project?
+Considering the difficulties I encountered during the process of writing this program, it was as rewarding as it was frustrating. It forced me to delve deeper into more of the computer fundamentals to successfully execute the program. Since I have never taken a digital logic type course and this was my first programming course, binary was a foreign concept to me. Furthermore, converting from decimal to binary or hex was even more foreign. I have learned everything from two's and one's complement, to format specifiers, to manipulating code in order to obtain the negative values in the range for the signed data types. In order to do this, I changed from bitwise AND to bitwise OR, as well as type cast to the unsigned counterpart of the data type. This was a surprise, as I happened upon changing from bitwise AND to OR, only in desperation to achieve what I knew the low values in the range were supposed to be. I kept second guessing MY logic, as well as the computer logic used in completing the assignment.
+**Observations**
+The long and long long int (signed and unsigned) appear the same. This is because they are both 64 bit and that is the most the compiler can handle.
+printf() and fprintf() basically do the same thing. The difference being that printf can only print on the monitor, has the default stream of STDOUT, while fprintf can print to a user defined stream (or file). In our project, fprintf uses the STDOUT to the screen AS if it were a file.
+STDOUT is by default printed to the screen unless user specified.
+%s is the format specifier used to print a string of characters, %hhu is the format specifier for half half unsigned char, % hu is the format specifier for unsigned short int.
+The difference between %u and %d are that %u denotes an unsigned int type, while %d denotes a signed int type.
+Considering the 13 in %13 in the first stanza for unsigned char in the program, this just specifies the number of characters in the string, including spaces to be printed for "TYPE".
+If a sign is left unspecified, it is assumed unsigned by default.
+The & and | operators are the bitwise logic operators, which in our case took the hex representation of our data types to help us to obtain the appropriate high/low values within our ranges.
+I experienced some difficulty in initial attempts to obtain the low values for the signed data types. I later learned that not only did I need to change the expression for the "low" values to bitwise OR, but I also needed to type cast in the final line of the signed data type stanza.
+Based on my program's output, the total bits allocated per the following data types are as follows:
+   * signed char = 8 bits
+   * unsigned short int = 16 bits
+   * unsigned int = 32 bits
+   * signed int = 32 bits
+   * signed long long int = 64 bits
+However, due to the decrementing and incrementing per data type, only the unsigned char actually stored ANY memory at all and stored a total of 16 bits!
