Write a cpp program to delete an element of an array using function

Solution

#include<iostream>
using namespace std;
int Lsrch(int [],int,int);
int main(){
    int arr[50],i,size,item,index;
    cout<<"Enter the desired size of array";
    cin>>size;
    cout<<"Enter the elements in the array";
    for(i=0;i<size;i++)
    {
        cin>>arr[i];
    }
    cout<<"Enter the element that needs to be deleted: ";
    cin>>item;
    index=Lsrch(arr,size,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;
    }
    for(i=index;i<size;i++)
    {
        arr[i]=arr[i+1];
    }
    size-=1;
    for(i=0;i<size;i++)
    {
        cout<<arr[i]<<" ";
    }
return 0;

}
int Lsrch(int arr[],int N,int ITEM)
{
    for(int i=0;i<N;i++)
    {
        if(arr[i]==ITEM)
        {
            return i;
        }
        
    }
    return -1;
}

Output
