    Thanks it worked for me.
    But i am kinda confused--> in the while loop u just used "FILE" as a length and u inserted the values in the vector "FOODS" using ""FOOD". How did it entered the values? I am not getting that part.

      He didn't use file as the length, he used file >> food. Which evaluates to true so long as there is stuff to fetch from the file. That's what the condition is. it checks to see if you can read from the file, if the check is successful, the while loop iterates, and the push_back() function adds the food item into foods. If it is not successful, we exit the while loop and then the rest of the program continues.

    if anyone can help, after I output something to a file I want to save the file, what do I do?

    • @etho7351
      @etho7351 3 месяца назад

      the file should automatically save when you close it and have the information you outputted to it

    Hi, I just want to create a file in cpp. I will update the contents of the file later. Can anyone share me the code for only creating a file? Sorry, I am actually confused with the C style file handling.

    • @abdul4515
      @abdul4515 Год назад +1

      #include
      #include
      int main()
      {
      std::ofstream file("filename.txt"); //change "filename" to whatever name you want.
      file.close();
      }

    Say you make this file, and it’s to read names. How would you get the file to sort the names in alphabetical order?

    • @saraalouh1877
      @saraalouh1877 Год назад +2

      You would probably need to create a function that will alphabetize a bunch of strings, then feed the contents of the file through it. You would probably need to save them to a new file, or find a way to delete the contents of the first file and reupload them to it.

    • @TheHset

      You would have to create your own sorting algorithm and have some form of temporary string storage, as Sara said.

    Please, do not use string or the bloat amount of libraries except for and . This is about new programmers learning C++.
