Class introduction to lab46 Regained some familiarity with the lab46 server, trying to remember useful Unix commands.
- SSH lab46 (to log in)
- screen -r (reconnects to the class IRC)
- Ctrl+d (disconnects from IRC)

C - LAB 1
Joe attempted to re-familiarize the class with Bitbucket.org repository. CSCS1320F13 If not already Joe should have a rule of 3's
Functions -
- Name
- Input
- Output
Variables -
- Name
- Value
- Data Type
Hierarchy of programming language
- C - Higher level language
- Translate / compile (GNU Linux - gcc)
- Processor - Instruction set, machine code referred to as assembly
Preprocessing commands
#include <stdio.h> (has standard i/o functions like printf)
Hello World Program
Joe walked us through writing our first C program to gain some insight on how we use commands to get output from a program. So, opening vi editor and typing in the following commands gets us some output in the form of “Hello World”
Some of the basics of VIM I can remember:
- Cursor navigation - h ←, k ↑, l →, j ↓
- ESC for command mode
- Exit vim with out saving- :q!
- Save and exit - :wq or SHIFT+zz
- x - deletes selected character
- i - inserts , or a in command mode to append
Once our program was hastily written we needed to compile the program using GCC (GNU Compiler Collection). The command used was as follows. $gcc -Wall -o filename hello.c

- int
- long int
- long long int
Floating Point
- float
