Linear Search in Python and C++

    Here in the program, we will code to find an element stored in an array, using the linear search algorithm.

    Linear Search in Python and C++

    In linear search algorithm we will transverse through every element of the array and print out the array index number where we find the element:

    C++: 

    #include<stdio.h>
#include<conio.h>
#include<iostream.h>

void main()
{
clrscr();
int n,find,arr[50];
cout<<"How many elements you want to enter? ";
cin>>n;
cout<<"Enter the elements in 1-D array\n";

for(int i=0;i<n;i++)
    cin>>arr[i];

cout<<"Enter the element you want to find: ";

cin>>find;

for(int j=0;j<n;j++)
   { if(arr[j]==find)
     {  cout<<"The element "<<find <<"is at " <<j <<" index";
        break;
       }
   }
getch();
}

    Output: 

    How many elements you want to enter? 5

Enter the elements in 1-D array

1
2
3
4
5

Enter the element you want to find: 3

The element 3 is at 2 index

    Python Linear search: 

    arr=[]
n= int(input("How many elements you want to enter? "))
print("Enter the elements in 1-D array")
for i in range(n):
    elements = int(input())
    arr.append(elements)
find= int(input("Enter the element you want to find: "))
for i in range(n):
    if arr[i]==find:
        print("The element",find, "is at",i,"index")
        break

    Output: 

    How many elements you want to enter? 6

Enter the elements in 1-D array

12
42
12
34
576
3

Enter the element you want to find: 576
The element 576 is at 4 index
