How to delete and edit a line in text file c++

Hello I am beginner in C++. I programmed a code for deleting and editing time of movies in text file. But I have stucked there. The program is deleting all the data in the file. Can someone help me with this? I have attached the arrangement of movie just like how I arranged in text file which is "Movies.txt"

Avenger|09:30|08:00|07:00

Policeman|09:30|08:00|07:00

Superman|09:30|08:00|07:00

Batman|09:30|08:00|07:00
