  1. as a bigner i have a simple program for linear search.
    #include
    #include
    void main()
    {
    int list[5]={10,20,30,40,50};
    for (int i=0; i<5; i++)
    cout<<list[i]<<"\t";
    int key,loc;
    loc=-1;
    cout<> key;
    for(int i=0; i<5; i++)
    if (list[i]==key)
    {
    loc=i;
    i=5;
    }
    if (loc==-1)
    cout<<"\n SEARCH UN-SUCCESSFULL";
    else
    cout<<"\n SEARCH SUCCESSFULL";
    getch();
    }
