 On a different system, you can use "hg pull" and "hg update" to update your changes on different systems, allowing you to save and load your work on lab 46 or on your personal system.
 =====BUILD THE CODE=====
+Can use https://learn.microsoft.com/en-us/cpp/c-language/cpp-integer-limits?view=msvc-170 to help you find the max and minimal for long/short signed/unsigned
+Example
+ value              = 0x7F;
+    fprintf (stdout, "maximum value represented: %hhd\n", value);
+x7F = 127 so the maximum value for a signed char would be 127
 =====RUN THE PROGRAM=====
 You can do "make" to compile and if you get an error you can do "make debug"

 ====STORAGE: BITS AND BYTES====
-Recall there are 8 bits in 1 byte
+The default byte size is 4, so hh (char) is half of half [(4/2)/2= 1 byte]; h (short int) is half (4/2= 2 bytes); just int alone is 4; l (long int) is double (4*2= 8 bytes); and ll (long long int) is also 8 bytes.
-====BITWISE LOGIC: AND====
+Recall, there are 8 bits in 1 byte. After you know the size of the bytes, you can multiply that by 8 to find the number of bits (EX: byte size 4 has 32 bits).
+====BITWISE LOGIC: AND====
+to use AND logic, use the "&&" between two statements to say "this and this other thing"
 ====BITWISE LOGIC: OR====
