Implement a SAVE command in your main loop that will save all the employees out to a file. The SAVE command should ask for a file name, similar to the way your FIND command asked for a name. Implement a function readEmpFromFile that takes a FILE* as the only argument and returns a pointer to a struct employee. This function should read the information from the file (reversing what writeEmpToFile does), create a new employee and fill in the data. If the FILE has no more info (is at end of file), this function should return NULL. This function must also ensure any employee actually created (not the NULL) is added to the array (as is done in createEmployee). Change main to load employees from a file if a command line argument is given to the program (using your readEmpFromFile function you just wrote).

I have already started these changes I only need help with the section that is highlighted In the image the rest I have already done what I have so far as well as the code that you need to implement the changes to is in the link below

 

The function called readEmpFromFile this function is different and should not be mistaken with the function called  readEmployee

Each of these functions does something different than one another
