FILE *. It should write each field in order as an appropriate type. Note that you will probably want to wr a length of the name before you write the characters of the name. By doing this, when you write the load function below, you can read the length of the string and use it to malloc a buffer of th proper size to hold the name. Because of the embedded name pointer, you CAN NOT write the Employee struct as a single struct. You will need to write it out field by field. You will want to write this as a binary file, not as

Question

Please Implement your changes into the code that I have provided in the link below because That is what this question is asking to have done 

(This is the link to what I have so far)

Implement a function writeEmpToFile that takes two arguments: a struct Employee pointer and a FILE *. It should write each field in order as an appropriate type. Note that you will probably want to write a length of the name before you write the characters of the name. By doing this, when you write the load function below, you can read the length of the string and use it to malloc a buffer of the proper size to hold the name. Because of the embedded name pointer, you CAN NOT write the Employee struct as a single struct. You will need to write it out field by field. You will want to write this as a binary file, not as a text file. 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).
