Why doesnt this work?

[Ch1156]

I am trying to get the entire contents of a text file, and i am looking at this push back reference and I copied it almost the same, but It still wont work, why?

http://www.cplusplus.com/reference/string/string/push_back/

int main()
{
    std::cout << "Find and replace\n" << std::endl;

    std::string strToFind, strToSearch, replaceWith;
    std::string::size_type pos;

    std::ifstream openf("text.txt");

    while(!openf.eof() strToFind.push_back(openf.get()));

    std::cout << strToSearch << std::endl; //Debug Line

    FindandReplace(strToFind, strToSearch, replaceWith, pos);

    return 0;
}

EDIT: Errors are

The compiler says it right there, it expected a ')' before 'strToFind' on the line 17 (which is 10 in your code snippet).
Your while loop's closing parenthesis is after your push_back() line, you're trying to call separate functions/instruction inside the while condition.

while(!openf.eof() )
    strToFind.push_back(openf.get());
