All language subtitles for 1. Welcome to Class!

Hello and welcome to the sea for beginners programming class.

My name is Jason Fagone and I will be your instructor.

I want to thank you for signing up for this course.

It's going to be a ton of fun and I'm going to do my best to motivate you and help you learn all about

the C programming language.

Let's get started.

First I want to tell you a little bit about myself.

I have a master's of Science in Computer Science from Binghamton University.

Now I also have a bachelors of science and in computer science from SUNY Oswego I receive my master's

in 2001.

I've been a software developer for over 16 years.

I've been an online instructor for over 11 years.

I've instructed over 20 different classes ranging from everything from object oriented programming to

compiler theory.

I have a vast amount of experience with programming in computer science in general.

I've been working with the C programming language for over 16 years basically as soon as I got my first

job I started writing C code.

I've also created beginner C and advanced the classes in multiple universities.

So I've a good amount of experience with curriculum and presenting C concepts to students.

I've been a software developer Xerox Corporation for around 10 to 12 years why I've been working here.

I have been writing C code mainly and also some C++ code.

We run our entire source code repository on the Linux platform and we write real time code.

I mainly concentrate on object oriented languages and mobile programming.

This is what I love to do.

So things like C++ and Java but the C language is really well I have my expertise in.

I also focus on writing high quality code.

This is an invite all important concept that I'm going to emphasize throughout the course.

I want you guys to focus on writing good code not just writing code that works but writing good code

that will help the maintenance of the program be much easier.

Some of the topics we are going to cover in the class.

Include the following.

And by the way when we cover these topics we're going to provide.

I'm going to provide lecture material.

I'm going to provide hands on exercises.

I'm going to provide assessments.

I'm going to walk you through code and programming concepts as I'm editing in an integrated divel environment.

So it's going to be really hands on.

We're first going to talk about C in general give you a little overview of it.

I'm going to tell you how the C programming language is very efficient.

It's also portable you can write it across multiple platforms.

It has a lot of power and flexibility and its programmer oriented.

Also provide you a short history of see just to give some context.

We'll follow that up by describing some of the common language features of C C is an imperative language.

This is the most modern type of language.

It's organized around functions.

It has a module design.

It's a structured programming language and you can also have top down planning when you're writing your

code.

The advantages of using C will focus on C is great for small fast programs it's very reliable very easy

to learn and very easy to understand.

If you were to take a C program from fellow peer fellow developer you'll be able to follow it pretty

quickly.

We're going to use a modern cross-platform integrate and develop an environment which is Microsoft Visual

Studio code.

You can use this on multiple platforms from Mac to Linux to Windows and we're going to be doing all

of our developing using this idea.

We're going to edit code we're going to also use the idea to debug our code which is very important.

And so this will be presented as one of the concepts I'll kind of walk you through the environment and

show you how to use the tool Well first going to start off with basic concepts.

I want to describe to you what a C program looks like and give you an example.

I'm going to show you the structure of a basic C program.

We'll talk about how you can provide comments in your code and also basic output using the print f function.

We'll go through a hello world example and also have you write your first program in C.

We'll follow that up with talking about make files.

We won't go into a lot of details about make files but I want to touch on it to help you understand

how you can use this tool to build to compile your code we're going to talk about the base most basic

programming concept there is which is creating in using variables variables is the idea of associating

memory data and memory for your program with a name and you're going to create many variables and many

different statements in your code.

We'll talk about data types which includes the inflow into our data types and then later in the class

we'll talk about more advanced data types like in arms and then providing your own data type by using

a typedef keyword I'll provide information on basic operators.

These are things like doing addition or subtraction math operators.

It also includes all logical operators like andere or this would be in kind of like decision statements.

We'll talk about how you can assign data to a variable using an assignment operator making decisions

in your code.

Very important programming concept.

We'll touch on this.

These are called conditional statements.

These are key words like if and switch will provide examples and go through the various constructs of

this file that up with talking about repeating code mainly looping the big looping constructs in C R

for a while and do while they're all the same they're just a little different syntax.

We're going to talk about how you can store data and categorize data to different using race.

So we'll discuss how you can define initialize arrays and then multi-dimensional arrays which is kind

of like a matrix spreadsheet type of concept functions.

Functions are one of the biggest most important concepts related to the C programming language.

Everything shouldn't be should be used in organized or on a function.

This is referred to as module type programming.

You're going to learn how to declare a function how to use it how to pass data to it how to return data

from it.

We'll also talk about more advanced concepts like call by value and call by reference debugging.

Debugging is a vital concept in essential for all programmers.

It's this idea of finding and fixing your errors.

We're going to discuss the call stack which can show you if your program crashes where it crashed.

Very important concept I'll provide you with common mistakes that many C programmers make so that if

you do see these mistakes do you understand how to fix them.

And then the compiler the compiler will check your code to make sure it's technically correct and if

it's not it will give you error messages or warnings.

You need to understand what the compiler is telling you.

So we'll talk about the compiler messages and how to understand them.

We're going to discuss Atrox you're going to learn all about stocks which is similar in arrays and that

it stores data.

It's a data structure.

We're going to discuss how you can initialize stocks how there's this concept of nested structures.

For those of you that are familiar with objects it can be kind of relatable to that but it's not as

robust character strings which is essentially a string in C alphanumeric characters inside double quotes

this is one of the basic data types but it's thought of as an array and see it's a little different

concept.

We're going to go through that.

We're going to talk about some of the operations you can perform on strings and so forth.

Pointers pointers are probably going to be our most important concept in this entire course.

So we're going to spend a lot of time on it.

Pointer's is this concept and see where you have to manage your own memory.

It Mavia not familiar concept to you if you program in other languages because this is usually done

for you specifically if you program job or C-Sharp you don't have to worry about pointers in C you have

to worry about managing your own memory.

So pointers are a big deal.

I'm going to tell you how you can define and use pointers how you can use them with functions and arrays

how you can call different standard library calls to create memory and also how you can dereference

pointers is an important concept like I said and we're going to spend a lot of time on this.

I'm going to provide you with a lot of examples a lot of real world type scenarios so that pointers

are really driven into your brain because you can't use the C programming language without fully understanding

pointers.

We spend a lot of time on this.

The preprocessor we're going to learn about this is the step that happens before the compiler specifically

there are directives that you need to understand like define and include we'll go through that.

We're going to go through input and output.

You can read write data to the cons..

We talked about print if we're going to go in a little more detail into that by using get Charen scan

format specifiers things like that.

We're also going to talk about how you can read and write data to a file.

This is another sort of important concept when you're writing code.

It's a way of storing data.

There are many different file operations in C and we're going to discuss some of those.

C is a very low level language in that it can do a lot of things efficiently and fast in file writing

and reading is at that low level it can interact with the operating system pretty pretty nicely.

There's a standard C library that comes with the C programming language where there's a lot of different

functions that you can utilize their string functions string manipulation functions math functions utility

functions.

We're going to go through all these basic functions that you can use that help you write code more efficiently

just like different libraries and other languages.

C is going to provide you with some of the basics again in order to write and read from files.

Manipulating strings if you want to get cosign tangent for math functions.

That's all provided for you by the language.

We're going to learn about that.

And those are the main topics that we're going to cover beginning topics.

We're not going to go into any advanced topics yet but we're going to cover the basics fundamentals.

So at the end of this course you should be able to write beginner C programs understand the fundamental

aspects of the C language know how to provide input and output to file.

I'll drill down the concept the pointers etc..

You're also going to as we go through this course.

Focus on writing high quality code efficient code.

This is very very important again.

It affects the maintenance phase the software lifecycle.

So if you want to find and fix your errors it's much easier to do that if you have high quality code.

So as we go through examples as we learn these concepts we're going to learn how to do it the right

way.

We're going to learn how to make things modular so that things are grouped in the functions we're going

to make sure that in our different files we have low dependencies low coupling so that they don't affect

one another.

When you have a lot of dependencies in your code you can it's much easier to find and fix your bugs.

And if you ever want to add new functions or add new code to a program it's much easier to do that if

it's modularized if it's going or as a function.

So we're going to focus on this concept of writing high quality code we're not just going to get things

to work we're going to do it the right way.

At the end of the Course you'll be able to find and fix your own errors.

An essential part of becoming a good programmer is problem solving.

We're going to focus on problem solving techniques and how did the bug your code and how for you to

become an efficient problem solver.

This includes understanding the compiler messages it understands how to run a debugger how to use the

call stack.

All these nice things.

Problem solving is going to be drilled in in all lectures.

You're going to understand the fundamental aspects of the C program.

The topics I mentioned previously this is going to be basic C stuff.

Lastly you're going to have fun.

I'm going to do my best to motivate you.

I'm going to have fun exciting examples.

I don't want you to fall asleep during lectures or exercises.

So I to make them lively and I want to do my best to motivate you and help you throughout this course.

So I'm looking forward to it.

I'm really excited and I hope everybody is ready to learn a lot about the C programming language.

Thank you.
