Linear search program in c using recursion

This program runs linear search recursively in an array c++ code

Concept used:

• Recursive function Linear Search
• if else statement
  
  
  

How Program Works

• Program takes size of array
• Input elements in array
• Passing array, key and size to the recursive function recursiveLinearSearch(int array[],int key, int size)
• Recursive function calls it self until certain conditions fulfill
• Function returns 1 if record found in array else returns -1

C++ code:
C++ program linear search program using recursive function

#include<iostream>     using namespace std;        int recursiveLinearSearch(int array[],int key,int size){     size=size-1;       if(size <0){       return -1;       }       else if(array[size]==key){       return 1;       }       else{       return recursiveLinearSearch(array,key,size);       }     }       int main() {          cout<<"Enter The Size Of Array:   ";     int size;     cin>>size;     int array[size], key,i;          // Taking Input In Array     for(int j=0;j<size;j++){     cout<<"Enter "<<j<<" Element : ";     cin>>array[j];     }     //Your Entered Array Is     for(int a=0;a<size;a++){        cout<<"array[ "<<a<<" ]  =  ";        cout<<array[a]<<endl;     }     cout<<"Enter Key To Search  in Array";     cin>>key;     int result;     result=recursiveLinearSearch(array,key,size--);     if(result==1){     cout<<"Key Found in Array  ";     }     else{     cout<<"Key NOT Found in Array  ";     }        return 0;     }

By Lee Smith

Are you in the market for a new computer? Have you begun shopping for a new computer, but dont know what you are looking for? You arent alone. Many people get confused when it comes to computer shopping. Read on to get some great suggestions how to simplify the entire process.

Always have anti virus on your desktop. Without such a program, malicious software may infect your system. Malicious software programs can hijack your personal information and slow down your computer processing speed. There are several programs available that can scan and repair your computer regularly.

Try and find somebody who is giving away their desktop computer. A lot of people are making the shift to laptops and tablets, so they are attempting to sell their desktop computers for an affordable price. Usually, these computers are in good shape, but before making an offer, be sure that the computer works fine.

If you desktop is slow you can do a boot check to get more speed. You will be able to find this information in the start menu. Then, check out programs that are starting when you start your computer. If there are some listed you do not use often, disable them. Your computer is going to run a lot faster when you do this.

Look for the desktop computer model that suits your needs without exceeding your budget by too much. A lot of people look for machines with too many expensive add-ons that they will really never use. Be selective about the features and components in your desktop purchase to save money.

Compile a list of the tasks you plan to use your computer for, prior to shopping. Which computer you buy is going to have to do with what operations and activities you will be doing. If you intend to do serious gaming, your hardware requirements are going to be much higher than someone who just surfs the Internet.

Check out various reputable tech sites to evaluate any computer before making the decision to buy it. The many available choices can be overwhelming, but checking out reviews or the "editors pick list" will help you decide which computer is worth the money.

Youll need to consider a few things when buying a high-end gaming computer. Your system needs a solid video card, no less than 4 GB in memory and a higher resolution display. You can also get keyboards and controllers specially designed for a better play experience.

Be diligent in your purchasing; a great deal of the information is now online instead of in a booklet. Check out the online information before you purchase to make sure it meets your needs.

Make sure the software on the computer you want to buy is legal. You always should have the key and CD to be sure you wont end up in legal hot water or arent allowed to get later software updates.

Does the computer have enough memory? This is important when purchasing a PC. Will you need a lot of space? Will you be adding a large number of pictures?

Read reviews about computers online. Dont choose a desktop solely on price or looks. Most of the time, cheap computers are that price for a reason.

Are you someone who needs storage for lots of pictures? Memory questions are very common from desktop computer shoppers and you should be able to get good advice from retail store personnel as well as the computer manufacturer about memory capacity and issues for specific desktop computers.

Do not be worried! You have gained more than enough information to begin searching for your perfect computer. It is even possible to print out this article and bring it with you. If youre still in need of assistance, an employee can assist you finding the computer that best fits your needs.

Insertion and Deletion of elements in an Array

Suppose you are storing temperature data for a few months and you forgot to
store the temperature of a particular day (say 5th day) then you need to INSERT
that temperature after the 4th element of the array and in the other case if
you accidentally stored duplicate data then you need to DELETE the duplicate
element.

Apart from these simple examples, there are many other uses of insertion and
deletion

The array to which the element is to be inserted or deleted can be of two types
unordered (unsorted) and ordered (sorted). Here we will be discussing about
the insertion and deletion of element in an unordered or unsorted array.

For insertion in these types of arrays, we need to have two information, the
element to be inserted and the position to which it will be inserted. For deletion,
we only need the position.

Suppose we have the following array:

arr[5]={5,7,2,1,3}

And we need to insert the element 6 at the 2nd position, after insertion:

arr[5]={5,6,7,2,1}

Notice how the last element of the array (i.e. 3) has gone out to compensate
for the insertion.

Now, suppose we wish to delete the element at position 3rd, after deletion:

arr[5]={5,6,2,1,0}

We see, all the elements after the 3rd have shifted to their left and the vacant
space is filled with 0.

That’s exactly how insertion and deletion are done!

Algorithm for Insertion of an element in an array

Suppose, the array to be arr[max], pos to be the position
at which the element num has to be inserted. For insertion,
all the elements starting from the position pos are shifted
towards their right to make a vacant space where the element num is
inserted.

1. 
   

   FOR I = (max-1) TO pos
        arr[I] = arr[I-1]

   
   


2. 
   

    arr[I] = num

   
   

Yeah it is that simple!

Algorithm for Deletion of an element in an array

Suppose, the array to be arr[max], pos to be the position
from which the element has to be deleted. For deletion, all the elements to
the right of the element at position pos are shifted to their
left and the last vacant space is filled with 0.

1. 
   

   FOR I = pos TO (max-1)
        arr[I-1] = arr[I]

   
   


2. 
   

   arr[I-1] = 0

   
   

Now, to illustrate all this let me show you a simple example program:

  // Example Program to illustrate
  // insertion and deletion of
  // elements in an array

  #include<iostream.h>

  // array has been declared as
  // global so that other functions
  // can also have access to it
  int arr[5];

  // function prototype
  void a_insert(int, int);
  void a_delete(int);

  void main(void)
  {
   int ch;
   int num,pos;

   while(ch!=4)
   {
    cout<<"1> Insert";
    cout<<"
2> Delete";
    cout<<"
3> Show";
    cout<<"
4> Quit
";

    cin>>ch;

    switch(ch)
    {
     case 1:
     cout<<"enter element:";
     cin>>num;
     cout<<"enter pos.:";
     cin>>pos;

     a_insert(num,pos);
     break;

     case 2:
     cout<<"enter pos.:";
     cin>>pos;
     a_delete(pos);
     break;

     case 3:
     cout<<"
Array:";
     for(int i=0;i<5;i++)
       cout<<arr[i]<<" ";
     break;
    }
    cout<<"
";
   }
  }

  // insertion function
  void a_insert(int num, int pos)
  {
   for(int i=4; i>=pos;i--)
     arr[i]=arr[i-1];
   arr[i]=num;
  }

  // deletion function
  void a_delete(int pos)
  {
   for(int i=pos; i<=4;i++)
   arr[i-1]=arr[i];
   arr[i-1]=0;
  }

Good-Bye!

Web 2 0 Extremely easy web programming

While I am busy working on Liberty BASIC v5.0, my development partner Scott is working on something fun on the side. We are working on a dynamic web front end to Liberty BASIC so that you can write web programs in LB. We have some ideas for a unique tool for web programming that doesnt require all the crazy bits and pieces that are needed for the mainstream web solutions.

This will be an all-in-one solution with its own web server and it can be hosted behind Apache if so desired. We hope that in a month or so we will have a neat demo site up with some example pages that show how it works.

So, theres lots going on! :-)
