Java program to sort a given array

Java program to sort a given array.

Code :

class Array{
    int a[]={9,7,4,-1,0};
    voidsortArray(){
    int i,j,temp;
    for(i=0;i<a.length;i++){
        for(j=0;j<a.length-1;j++){
            if(a[j]>a[j+1]){
                    temp=a[j];
                    a[j]=a[j+1];
                    a[j+1]=temp;
                }
            }
        }
    }
    voidshowArray(){
        for(inti=0;i<a.length;i++){
            System.out.print(" a["+i+"] : "+a[i]+"\t");
        }
    }
}
class Sort{
    public static void main(String args[]){
        Array t=new Array();
        System.out.print("\n Array Elements : \n ");
        t.showArray();
        System.out.print("\n Sorted Array Elements : \n ");
        t.sortArray();
        t.showArray();
    }
}

Output :

Array Elements :
  a[0] : 9       a[1] : 7        a[2] : 4        a[3] : -1       a[4] : 0

 Sorted Array Elements :
  a[0] : -1      a[1] : 0        a[2] : 4        a[3] : 7        a[4] : 9

C++ program to find a binary equivalent of a number using recursion

Given below is a C++ Program to find a binary equivalent of a number using recursion.

Example :

2 / 14 = 7 Quotient | 0 Remainder
2 / 7 = 3 Quotient | 1 Remainder
2 / 3 = 1 Quotient | 1 Remainder
2 / 1 = 0 Quotient | 1 Remainder

Now take all the Remainder in reverse order. Now we have 14 = 1110₂.

C program to implement Insertion sort

Given below is a C program to implement Insertion sort.
What is Insertion sort? Click here to read about it.
In Insertion sort the element is positioned at its proper place by inserting it and shifting the other elements to the right. The elements are sorted in increasing order of their position.

Example :

75 35 47 15

Pass 0 : 75 35 47 15
Pass 1 : 35 75 47 15
Pass 2 : 35 47 75 15
Pass 3 : 15 35 47 75

C program to implement Bubble sort

C program to implement Bubble sort.
What is Bubble sort? Click here to read about it.
Bubble sort can be used to sort the items in ascending or descending order. It involves iterating through the list and swapping the adjacent elements until the list is sorted that is no swaps are needed.

Example :

45 36 28 10 5

Pass 0 :  45  36  28  10  5
Pass 1 :  36  28  10  5   45
Pass 2 :  28  10  5   36  45

Having problems while running C or C++ program ?

Many a time beginners are faced with the problem while running a C or a C++ program. The common being not able to compile and run it. The error's like

Unable to open include file 'IOSTREAM.H'
Unable to open include file 'CONIO.H'
Unable to open include file 'STDIO.H'

It seems to give an error for every file included using #include. Its common to have such errors since people usually place the TurboC or TC or TurboCPP folder according to the location they prefer in the partition.

Method 1 :

Placing it in the partition where Windows is loaded could solve this problem.

Locate the folder TC or TCPP or TC++ or TurboC
the above names may differ according to the source you have 
acquired it from
Copy the folder
Go to the partition where you have installed your Windows 
operating system
Open the partition
Paste it 

After installation the path should be like [drive :]\TC . Where drive is the letter of your partition which in most of the cases is C. You can use the below method if still you aren't able to run the program.

Method 2 :

Alternatively if you dont want to place the folder in windows partition you can follow the steps below to solve the problem.

Locate the TurboC or TCPP folder
again names vary according to sources you have acquired it from
Open the bin folder
Click TC.EXE
In the IDE or the window you are working in locate the menu bar 
at the top
Click on Options in the Menu bar
Click on Directories
Now besides Include Directories type the whole path to where you 
TC is located. For example
[drive : ]\path\tc\include
Now do the same for the text field located besides 
Library Directories. For example
[drive : ]\path\tc\lib
For Source and Output directories do the same. For example
[drive : ]\path\tc

Note : By default the path specified are relative paths and hence dont work in partition's other than Windows. When you place your TCPP or TurboC folder in location other than Windows partition you have to explicitly mention the path to directories.

Note : If you feel something is incorrect or missing leave a comment below.

Setting path for running Java programs

The path is an environment variable in operating system like MS Windows,Linux. This variable can be set to values as per users convenience. The path environment variable is usually set so that it enables to compile and run Java program directly from any directory without having to set the path again and again.

Steps to set path :

Method 1 : 

Click on start menu
Click on Run (Alternatively you can press Win+R keys)
Type cmd in the run window and press Enter key
In order to compile Java program you need to set path
set path=[drive:]\Program Files\Java\jdkx.x.x_x\bin;
where x.x.x_x is the version

Note : The above method requires you to set the variable for every new instance of command prompt window opened.

Method 2 : 

Right click on My Computer icon on Desktop
Click on Properties
Select the Advanced tab from the System Properties window
(Alternatively you can press Win+Pause/Break keys)
Click on the button named Environment Variables
In the Environment Variables window find variable named PATH under 
System variables and select it
Either double click the selection or click on Edit option below
In the field named Variable value put a semicolon (;) 
at the end of line (to go to end of line press the END key).
Copy paste the whole path to the bin directory in java
[drive:]\Program Files\Java\jdkx.x.x_x\bin
where x.x.x_x is the version
Click Ok in Edit Environment Variable window
Click Ok in Environment Variables window
Click Ok in System Properties window.
