This worked perfectly! The way you explained everything in a step by step way was a huge help. One other thing I really need help with though is how to search a text file for a string? I have looked everywhere and tried using Getline() and the search function in a loop, similar to what you did here...but I can't get it to work. All I would need it to do is tell which line in a text file the string was found.

Nice video, would be nicer if you kept the code a bit more zoomed out to get the big picture. Especially towards the end. Cheers

The file.eof() function does not work correctly for reading objects from a file as it copies one extra object. Does it not do the same for reading text data?

How do I take a string (which is a substring of the file) as my user input which I want to search in the file and print out only the line containing that substring.

Example: In my menu.txt file there is a line "Pizza cost: $4"
In my program file I take a user input as "Pizza" and I want the entire line "Pizza cost: $4" to be displayed and not the other lines.

So the while loop reads the next line automatically if the current line is not same as line number and the end of file is not reached?

you could do while ( getline (file, line, '\n') ) { }

Hello Sir, i've been looking everywhere for an algorithm, to find a specific word in a string on lines , example "hello world, welcome to c++, tutorial", i want to search the file, let's say to find, "c++", i wrote a search function, to look inside array or vector, result same it's only finding, the first element "hello" and disregarding the other elements, any tutorial about that would be appreciate it, big thank you .
