====== LABs ======



===== LAB 1 =====

Lab 1 is {{:lab_1.pdf|here}} for lab 1, the grade is on attendance. You must submit the deliverable during the lab time.

You  will get a marking report for the program but it will not be counted towards your final grade. This is only an example of how we mark your work.

<fc red>**Always check the lab during the lab hours. Some times there will be some changes/modifications to make it clearer. The changes are in bold red font so it will be easy for you to spot it ** </fc>

===== LAB 2 =====

Lab 2 is {{:lab_2.pdf|here}}. I will post soon samples input and outputs. You have to prepare your own set. My set will not cover all scenarios.

here is an example {{:in.txt|in}} file and {{:out.txt|out}} file

Please use od to see the contents of the files.

a detailed description is {{:ee.txt|here}}. Every line contains the stock price, the changes from the previous day, and the action taken

<fc red>**labs are due midnight Friday ** </fc>

here is one way to implement lab 2 {{:invest.c|invest.c}} note that the programs explain what is happening every day not just prints the results


===== LAB 3 =====

Here is {{:lab_3.pdf|Lab 3}}  (n < 50)

And here are some {{:practice_3.pdf|exercise}} problems (do not submit)

some {{:lab3_in.txt|input}} and {{:lab3_out.txt|output}} files

<fc red>**A BUG in the OUTPUT SAMPLE ** </fc>

<fc red> please add one line to the output sample file.

That line is</fc>

<fc red>123456789  Aboelaze </fc>

<fc red>That line should be added after the second or third line in the output file. Since I didn't specify the order multiple top students should be displayed, either order is fine </fc>

===== LAB 4 =====

Here is {{:lab_4.pdf|lab 4}}

**<fc red> You can assume that the maximum record length is 50 and the maximum value for k is 256</fc>**

Also note that I am asking for the number of entries with collisions, not number of collisions.

here is a sample {{:input.txt|input file}} and the corresponding {{:lab4_out.txt|output file}}

here is another {{:1.txt|input file}} and {{:sample.txt|sample}} output detailing the hash table enry. This is not what you should submit, just to help you with debugging I displayed the number of elements mapped to each hash table entry

**For both cases, k=10**

Here is one way to implement {{:hash.c.txt|hash.c}} this is just one way of doing it. There are many other ways, some may  be even more efficient.


===== LAB 5 =====

Here is {{:lab_5.pdf|Lab 5}}

**<fc red> Note the new due date (feb. 22) </fc>**

I will be posting test cases and binary files soon

** Submit as books.c to L5 **

**Text Cases** 

If you run the program for the first tome (no book.dat) with this input
{{:in1.txt|}} the output is {{:out1.txt|out1.txt}}  and the file {{:book_dat.txt|}} (rename this file to book.dat, it could not be uploaded with extension .dat

if you run the program the second time with book.dat as before,
the input is {{:in2.txt|}} and the output is {{:out2.txt|out2.txt}}


===== LAB 6 =====

Here is {{:lab_6.pdf|Lab 6}}

<fc red>**The student names are 50 characters or less ** </fc>

Due midnight Sunday March 5

**Now few pointers:**

You will read from the standard input, the number k followed by names. If you use scanf to read K, then use fgets to read names (it might contain spaces, so you can not use scanf easily), you will have a problem getting rid of the newline after the number k.

I would suggest to use fgets t read both, then use sscanf to read k from the string you read.

So, instead of

scanf("%d", &k);   you can use

fgets(s, sizeof(s), stdin);

sscanf(s, "%d", &k);

**records file**

{{:records.txt|records.txt}}

**Input and output files**

{{:l6_in1.txt|}} and {{:l6_out1.txt|}} for the given file records.txt

**This is not input output samples, but will help you to be with testing**

This is a hash table with k=7 {{:det7.txt|}} it shows the hash table with the records mapped to the different lists, the records are <name, final_mark> the fial mark is between two parenthesis.

Here is for k=10 {{:det10.txt|}}

**Here is a solution for lab 6** {{:l6.c|L6.c}}


===== LAB 7 =====

Here is {{:lab_7.pdf|lab 7}}

**<fc red> The lab is due March 19  </fc>**



===== LAB 8 =====

here is {{:lab_8.pdf|Lab 8}}

Due last day of classes
