Cpp program to linear search an element in an array using function

Write a cpp program to search an element in an array using function

Solution

#include<iostream>
using namespace std;
int Lsearch(int[],int,int);
int main(){
    int arr[50],ITEM,index,n;
    cout<<"Enter the desired array size";
    cin>>n;
    cout<<"Enter the elements";
    for(int i=0;i<n;i++)
    {
        cin>>arr[i];
    }
    cout<<"Enter the element to be searched for :";
    cin>>ITEM;
    index=Lsearch(arr,n,ITEM);
    //cout<<" Index is: "<< index;
    if(index==-1)
    {
        cout<<" Element cannot be found"<<endl;
    }
    else
    {
        cout<<"Element found at index "<<index<<",position "<<index+1<<endl;
        return 0;
    }
   
}
int Lsearch(int arr[],int size, int item)
{
    for(int i=0;i<size;i++)
    {
        if(arr[i]==item)
        {
            return i;
        }
        
    }
    return -1;
}

Output

Enter the desired array size 5

Enter the elements

1

3

45

67

23

Enter the element to be searched for : 67

Element found at index 3,position 4
