Linear Search using C++

Program Code:


#include<iostream.h>
#include<conio.h>
int linearSearch(int a[],int,int);

main()
{
int arr[50],size,index,target;
cout<<"Enter the size of array(max 50):\n";
cin>>size;
cout<<"Enter the elements of the array:\n";
for(int i=0;i<size;i++)
{
cin>>arr[i];
}
cout<<"Enter the element to be searched:\n";
cin>>target;
index=linearSearch(arr,size,target);
if(index==-1)
{
cout<<"Element is not present in the list\n";
}
else
{
cout<<"Element is present at index "<<index+1;
}

getch();
}
int linearSearch(int a[],int s,int t)
{
for(int i=0;i<s;i++)
{
if(a[i]==t)
{
return i;
}
}
return -1;
}
