Remove text from external file....

To whom it may concern,

I'm working on this program that require to remove text from the external file:
Ex. test.dat
I like this
you like that
Bluh bluh

int main()
{
istream read;
char temp[100];

//read from the external file line by line and store it somewhere... how?
cout <<"Enter line or the first word to be remove:" ;
cin.get( temp, 100, '\n');
//user enter "I like this"
//and then compare the two line or word.. then delete the alike from the "test.dat". So, what it has left is just:

"test.dat"
you like that
bluh bluh

}

Thank you in advance.

Read the FAQ!

The examples that you were giving me from the faq page is just an example is reading text from the file and cout to the screen. What I need is to read text from the file and delete text from that file...

thank you,

Read text from file into an array
delete text you don't want from array.
Write array back to file.
