delete a word
can anyone give me a general syntax on how to delete a specific word from a text file.
for example the menu choice is delete a word and it prompts the user to enter the word to be deleted.

Read the entire file into memory. (Use a std::string.)
Find and delete the word.
Write the entire string back to the file (replacing the old file).

If the file is very big like those web server logs, then you can exhaust all the memory. A simpler approach would be read a line process, read another line using back the same memory process etc etc.
No, it is not a simpler process; reading in parts is more complex than read-at-once.
If he is playing with web server logs or other huge files, then he knows enough about programming to choose a method more suited to the task. For whatever else he is doing, what I said will suffice.
