Dan DeNunzio's Fall 2013 Opus
Whatever
Introduction
Hello, my name is Dan DeNunzio, I have been working in the IT field for 15 years doing various jobs. I first gained my education and training while in the military as a network administrator for 7 years. After my time in the service I moved home to find a job and have been working at a local healthcare agency for almost 10 years as the IT Manager. My job has taken many forms and keeps me quite busy tending to the various gears of the IT machine there. I feel that I am well rounded in the technology field but lacking in the programming and alternative OS area. Some of my hobbies include learning and playing with 3d drafting and animation programs, fishing and most recently went broke on a marine aquarium that I have been learning to maintain.

Class introduction to lab46 Regained some familiarity with the lab46 server, trying to remember useful Unix commands.

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
