ofstream write("text.txt", ios::app);/*actually i am not sure what ios::app does*/

cout<<"firstname: ";
cin.getline(firstname,sizeof(firstname));
cout<<"last name: ";

Not a clue what you are asking. Maybe you need to explain the problem. Remember, we're new to it so details will help.

i hope to search for the word/phrase in my text file instead of print the whole text.

Read the links posted by me in the second post.

An eg.

string inStr;
string searchFor = "hello";
ostream in ("test.txt");

while (getline (in, inStr))
{
    if (inStr == searchStr)
    {
        //process
    }
}
