Help me please teach me how to delete a data on a txt file?

Load the entire file into memory.
Modify the memory.
Overwrite the file with the memory.
An easy way is to use a deque<string> to store the file in memory. Use the global getline() function to read lines from the file, appending them to the deque each time, until the file is exhausted.
Modify the deque.
Save the deque over the file.
Hope this helps.
