Programming Concepts
--------------------
Program
-------
A program is a set of instructions given to a computer to perform a task

Comments
--------
Comments are used to document a program and ignored by the programming language

Types of comments
-----------------
Single Line Comment (//)
Multiline comment (/* ... */)

Ex:
//to find area of a rectangle

Ex:
/*
to find gross salary and
net salary of an
employee
*/

Keyword
-------
A keyword is a reserved word whose meaning is known to the programming language
directly

Ex:
class, if, while, do, for, break, continue, public, private etc

Variable
--------
A variable is an identifier which allocates some memory space

Ex:
rollNum
student_Name
netSalary
customer_Address

Datatype
--------
Type of data the variable holds is called as data type

Ex:
int, char, float, String

Declaration of variable
-----------------------
In order to allocate memory space for variable we need to declare the variable

syntax (rules of a language)
------
datatype var1, var2, ..., varn;

Ex:
int a,b;
float f;

Function/Method
---------------
A function is a sub program which is used to do a specific task

syntax
------
Return_Type method_name(arguments)
{
st-1;
st-2;
...
st-n;
return ...;
}

Ex:
//Defining the method
int areaRect(int length, int breadth) //arguments or parameters
{
int area;
area = length * breadth;
return area;
}

//Calling the method
int area = areaRect(10,5);
print(area);//50

void areaRect(int length, int breadth) //arguments or parameters
{
int area;
area = length * breadth;
print(area);
}

void = means no return type
