C programming

Introduction

Before explaining C programming let us discuss what programming is ?????

 well programming is the set of instruction given to the computer , instruction to get our job done .

In our daily day-to-day life we also give instruction to others like “bring me that”  “complete the work” ,”go there” and etc .

So in computer science also we give instruction to the computer to get our job done like adding a bunch of numbers , finding solution to a mathematical problem , or doing some computational problem and so on

Like in English we follow grammar to complete our instruction like that we have specific way of giving instruction to the computer , and  as in our real life we have many languages to communicate similarly we have many languages we can use to write these computer instruction called programming languages and the instructions are called programs .

So that was a loose definition of programming language and programs

In the list of many programming language C is one of the oldest and popular programming language , it is small but can produce many complex programs and if you are interested in the history of C programming please visit this link  wikipedia C programming language

I won’t be describing a lot of detail on the theory part but still some information about C Language that I think you people should know

C Language is a procedural language that means it follows procedures or functions or sub routine in order to complete the task .
Well if you don’t know what a function is then not to worry you would know  later in the course but for now function can be defined as self contained unit of code

C Language is a multi platform language that means you can develop programs for almost all the major platform with C like windows , Linux , Unix etc , you just need a compiler and in case if you wonder what a compiler is , well I am going to explain it just wait for a moment

So that will be enough about the theory part , Now

What is the programming process?

The programming process follows like this

So first we have the source code that is the code we have written in C Language , we then compile the source code with a compiler , So compiler is a program that converts a user readable program to something that can be understood by a computer and after that we get a exe file or  executable file and then we run or execute the program

If the program executes well then its working fine but if not then it has a bug in it , a bug can be defined as a behavior of a program that we are not expecting , So in order to solve the problem we have to debug it , it’s the fancy way of saying “What Is Wrong In The Program”

We can start writing code in a command prompt which I find boring sometime so we would use a IDE  or what’s called as Integrated Development Environment , it’s a piece of software that we use to write our program and for this purpose I am using DEV C++ , its free and easy to install and use , you can download it from the following link Download

I hope you have downloaded it and install it

So to create a new program just do

File < New < Source File or just type ctrl + n (for new document)

Now we can write our program here

Let’s write our first program

main()

{

      printf("Hello World \n");

      getch();         

 }

That is it , now give a name to the program like “hello” with an extension dot c , so that will be “hello.c” and change the “save as type” dialog box to “c source file” and save the file

You can compile the program from going to the menu and

execute < compile (ctrl +F9)

and run the program by

execute < run (ctrl + F10)

The output of the program is to display “Hello World” message on the

console like

Now let’s examine the program

main()  {  }  - this called the main function , every c program should have a main function otherwise it won’t compile , at this point it might be difficult to understand what a function is but later it would be clear to you as we proceeds further but for now main is a function , 

every function has starting and closing round brackets following the function name and also opening and closing curly brackets which define the body of that function . Main is not the only function , there many more functions in C

function name ( )

{

Body of the function

}

Printf(“  “);  - well again this is also a function , and we do not see a body here don’t worry you will know about it later in the course but for now it’s a C function that accepts everything that is inside the double quotes and display it on the screen , that is the function of this function

printf(“ display this message on screen  \n“);

The semicolon – the semicolon is used to signify that “this is the ending of this statement” it’s like the “full stop” for programming language 

Statement ;

\n – slash n means new line , if you want to display two sentences one followed by other then use the \n character and if you don’t use it ,everything will appear in the same line

getch() – again we can see that it is a function , the function of this function is to hold the console until it gets an input from the keyboard and when we press any key the programs stops , if you have difficulty in understanding this then remove the “getch();” command and see how the program behaves and then add it again to see what do I mean here

Variables and Data Types

Ok lets learn the two very important concepts in C programming , variables and data types. 

So as the name suggest variable is something that is not constant that varies , we use variable in programming to store data , that could be numbers or text and data type defines the type of the data stored in the variable , so let me give an example to make it easy

Lets sat we want to store someone phone number in a program and display the number , so where we are going to store the number , we store it in a variable named “phone” (variable names are user defined , we give names to the variable , but there are some rules to follow , which I will explain very shortly)

So this would look like

Phone = value ;

Here value can be any integer

So this becomes

Phone = 123456;

This implies that phone is a variable to which we have assigned a value 123456

Now we also have to tell the compiler that “phone” can store what kind of value , like an integer or a character or a decimal value and so on and we tell this by using data type which tells the compiler  what is the type of data the variable can store , there are different key word for different data type and the major types are

int for integer value

char for storing individual characters

float for decimal value

double same as float but can store larger numbers  

please note that every data type has predefined range within which we can store values which we would discuss shortly

So to use a variable we write

int phone = 123456;

technically speaking variables are named piece of memory that we can assign a value , if you find that difficult , consider variables as a kind of box that we use to store data , the label of the box is its name and the type of content inside the box is its data type and the content is the value

Some rules to follow while naming a variable are as follows

1 > no two variables should have the same name in other words variables should be unique

2> variables name cannot begin with a number for example 123baby

3> variables can only have a to z , A to Z , 0 to 9 and underscore in it

4> variable have to be declared before they are used that means to specify the data type ,

 Syntax for variable declaration is

Data type variable_name = value_of_varibale ;

let’s find more about the integer data type

Data Type	Byte	Range
int	4	–2,147,483,648 to 2,147,483,647

In the above table the byte field represents the maximum size of a number an integer data type can hold and range displays that the number could be between negative 2,147,483,648 to positive 2,147,483,647 , so how we are getting this value ,
 well for information every data type has a certain range but to understand the relation between byte size and range let us do some binary calculation

So computer stores everything in bits that is zero or one , now 4 byte is equal to how many bits , 

since 8 bit is 1 byte so 4 byte will be 32 bit

8 bit = 1Byte

4Byte = 8 * 4 = 32 bit

So in binary if we have 32 numbers of 1s then the value in decimal form will be 4,294,967,295 but since int can store both negative and positive value this number splits in two equal parts including 0 , so the range splits in half to  –2,147,483,648 to 2,147,483,647  , but if we add these two values we would get 4,294,967,295 , this is how we get the  range from size , if possible try to find the other range by yourself ,
This link might be helpful to you Microsoft library

Enough with variables and data types now let us do a program with variable

 main()

{

int phone = 123456;    

 printf("Hello World \n");

printf("Your phone number is %d \n",phone);

getch();         

 }

This program display hello world followed by 123456

Now let us examine the new elements in the program 

int phone = 123456;   well this is not new , here we have declared a variable with integer type and assigned a value to it

printf("Your phone number is %d \n",phone);  printf is explained before , 
in order to display the variable in the statement we use the %d notation inside the quotes then a comma and then the variable name, 
please remember that the position of %d in the statement will decide the position of the variable in the statement , so it %d is before the word number then the variable will appear in that position

Now let us do a program with more numbers of variables

main()

{

int phone = 123456;    

int mobile = 9876543;

printf("Hello World \n");

printf("Your phone number is %d and mobile is %d \n",phone,mobile);

getch();         

 }

This is how we express multiple variable in a statement , here the first %d is for phone and the second for mobile variable

Some examples of how to declare and display other data type are

main()

{

float number = 55.5;    

printf("value of number is %f”,number);

getch();         

 }

 main()

{

double number = 44.54;    

printf("value of number is %lf”,number);

getch();         

 }

main()

{

Char car = ‘m’;

printf("value of character is %c”,car);

getch();         

 }

As we can see we have %f is for floats , %lf is for double and %c is for character
