Use the “hg add” command after you grab the project to add it to the repository.

Then use the “hg commit -m ”(message here)“” command to let yourself know any changes you made before adding it to your repository.

Then use the “hg push” command to finalize adding the file with the commit message.

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.

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);
  
  0x7F = 127 so the maximum value for a signed char would be 127

You can do “make” to compile and if you get an error you can do “make debug”

To then run it you do “./dtr0”

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.

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).

to use AND logic, use the “&&” between two statements to say “this and this other thing”
