LINEAR SEARCH for an array in c++

Linear search for an array

Linear search is used to search out the required number from a very large array of elements

#include <iostream>

using namespace std;

void main ()

{

          const int size=5;

          int a[size]={4,5,6,7,7};

         

         

          int n;

          cout<<"enter the no which you want to search:";

          cin>>n;

          bool found=false;

          for(int i=0;i<size&&!found;i++)

                   if(a[i]==n)

                             found=true;

                   if(found ==true)

                             cout<<"Number:"<<n<< "is found at location:"<<i<<endl;

                   else

                             cout<<"Number is NOT found";

}
