EmpFromFile
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 using a command called LOAD which is given to the program using (using your readEmpFromFile function you just wrote).
void main(void) {
int end = 1;
char * command;
char buff[256];
char * findEmp;
char findBuff[256];
char * sortType;

NB: Square bracket notation for array access is NOT allowed for Question 3, i.e. array[i]. Array access MUST be facilitated by the use of pointers.
Write a function, ReadFile(), that reads the content of the provided text file “Message.txt” and stores it in an array. The function receives as parameter a pointer to a character array where the content of the text file should be stored.. The number of lines that was read from the text file must be returned to the calling statement.
Write a function, ReverseMyString(), that converts the character array (which now contains the contents of the text file) by replacing the first character with the last character, the second character replaced with the second last character, etc, until the message is reversed as shown in the Figure 3. The function receives as parameters, a pointer to the character array and an integer value indicating the length of the array. The function returns a 1 or 0 to indicate success and failure respectively. NB: You…

- (Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.arrow_forwardC++ Progrmaing Instructions Redo Programming Exercise 6 of Chapter 8 using dynamic arrays.
