I need help making the readfromfile function use fstream ins

I need help making the read_from_file function use fstream instead of cout and malloc because i just get an abort message when i try to run my program with the function not commented out! Someone please help this is for a project i have due tomorrow! Here are the instructions to the Project. Thank You!

C201 Team Project 1 1 Goal The purpose of this assignment is to get you familiar with Streams and File IO, Your goal is to create a simple bank database (file) where all the individual accounts are stored in a file. 2 Requirements The following data should be stored comesponding to each account: Account Number: an integer number (must be unique for every account) Name: two words comesponding to the first and last name Balance: a float point number Your program should provide a menu of options that allow performing any of the following operations: Add an account Delete an account Search for an account by account number and display the account info Make a withdrawal Make a deposit Transfer money from one account to another List all accounts Your program should be coded in a way such that all previous changes are written to the file before any new operations are performed. 3 Testing Your program must be able to handle the following abnormal situations: For add an account option, if an existing account is entered, the program should respond with a message and no new account should be created For delete an account option, if the account number could not be found, a message should be displayed and no account should be deleted For withdrawal operation, if the account number does not exist or the balance is not sufficient, a message should be displayed and no changes should be made to the database For deposit operation, if the account number does not exist, a message should be displayed and no changes should be made to the database For transfer operation, if the source account number destination account number does not exist, or the balance of the source account is not sufficient, a be displayed and no changes should be made to the database 4 Notes Please ask the instructor if any part of the assignment is not clear. State your assumptions clearly. Document your code properly. Check and handle all error conditions related to file lo and logical errors related to account operations (e.g. overdraws). You must state clearly your team members at the beginning of the program. 5 Submission upload your source code files (cpp and h) using canvas. One team just needs to make one submission.
