If you want to remove text from the input file (as your description suggests but does not state).

Then you need to read line by line. But then each line needs to be parsed word by word to make sure you can remove the work you are looking for apple.

#include 
#include  

using namespace std;
// Don't do this. 

int main(int argc, char* argv[])
{
    if (argv == 1) { std::cerr << "Usage: Need a word to remove\n";exit(1);}
    std::string userWord = argv[1];  // Get user input (from command line)

    std::ifstream inFile("note.txt");
    std::ofstream outFile("note_new.txt");
    std::string   line;

    while(std::getline(inFile, line))
    {
         // Got a line
         std::stringstream linestream(line);
         std::string  word;

         while(linestream >> word)
         {
                // Got a word from the line.
                if (word != userWord)
                {
                     outFile << word;
                }
         }
         // After you have processed each line.
         // Add a new line to the output.
         outFile << "\n";
    }
}
