5. Lab Highlights Problem solving using C programming language
5 programming assignments, each consisting of 3-5 typical problems
gcc complier of departmental linux server will be used for lab and assignment purpose
You can use IDE like visual studio, xcode etc for learning
Keep up with Professor’s lecture. Try to utilize the lab hours efficiently.
Group study is helpful to share ideas about coding style and debugging techniques
You must work out your lab assignments individually
Google and YouTube are your best friends!!

6. Grading Rubrics

7. Let’s start!

8. 1st Program- “Hello, World!”
/* First program */
#include <stdio.h>
int main(void) {
printf("Hello, world!\n");
return 0; }

9. Basic Setup – Step 1
Claiming your Computer Science account: ts
*URL starting with wiki.cse.tamu.edu can not be accessed directly off campus. You need to use TAMU VPN for that. Details: N/index.php

10. Basic Setup – Step 2
Mapping your Home Directory (Already done in your lab computer, H: drive in file explorer)
You have to map H: drive in your own computer for remote access.
Windows: Type \\coe-fs.engr.tamu.edu\Ugrads in file explorer box
Mac: Using Finder, select Go to Server. Type smb://coe-fs.engr.tamu.edu/Ugrads in the box
A dialogue box will ask for authentication. Username is AUTH\your_netid and password is your TAMU password.
Details:
*URL starting with wiki.cse.tamu.edu can not be accessed directly off campus. You need to use TAMU VPN for that. Details:

11. 1. Create a folder
Create a folder named CSCE206 in your home directory
Within this folder, create another folder named Lab1
Remember, no space in file name or folder name!!

12. 2. Write the code
Using notepad++ or sublime text (or any text editor) open a file and write the hello world code
Save the file as my_code.c. Make sure that there is no space in filename.
Once the file is saved, the lines should change color

13. 3. Connect to Server(for Windows)
Open PuTTY and follow the instruction here under basic configuration:
Use linux2.cs.tamu.edu as host name. Press Save and then press Open
If you are doing this first time, a dialogue box will appear. Press Yes.
Use your netid and password for access

14. 3. Connect to Server(for Mac)
Open “terminal”
Type ssh –l your_netid linux2.cs.tamu.edu
Use your credentials to access the server

15. 4. Go to proper directory
You are currently in your home directory. Use linux commands “ls” and “cd directoryname” to navigate
ls lists all the directories and files in your current directory (directories appear blue, files appear green). cd allows you to navigate into the directory you specify.
To move back up to the parent level, use the command “cd ..”
Some basic commands:

16. 4. Go to proper directory Red boxes show the ls command
Blue boxes show the cd command

17. 5. Compiling the code
Once you are in the directory with the code file, run the command “gcc code_filename.c –o output_filename”
For this case, run the command “gcc my_code.c –o my_code”
If the code does not compile, it will show some error. Debug the code.
If the code compiles successfully, a new file named as output_filename(my_code in this case) will be created. Use ls command to check
Run “./output_filename” command to compile the code. In this case, the command is “./my_code”. You will see that “Hello,world!” is printed on console screen.

18. 5. Compiling the code Red boxes show the gcc command
Blue boxes show the output command

19. Congratulation! You have written your 1st code in the lab! 

20. Off Campus access
Download TAMU VPN. Use it to access the server. Link: Network_VPN/index.php
Map you home directory in you personal computer
Download and setup PuTTY for Windows. For Mac, use ssh terminal.
Now, you can access the server and use it for coding.

21. Practice Problem (Won’t be graded)
Problem 1. Write a program that prints out a two-line message of your own choosing.
Problem 2. Write a program with a char variable and an int variable and store the value 'E' and 5 in them. Print them on a line with a message saying what each one is.
Example: "char: E, int: 5"

22. Thank You!
