This is the C code I have so far 



#include <stdio.h>

 

#include <stdlib.h>

 

struct employees

 

{

 

char name[20];

 

int ssn[9];

 

int yearBorn, salary;

 

};

 

struct employees **emps = new employees()[10]; //Added new statement ---- bartleby

 

 

// function to read the employee data from the user

 

void readEmployee(struct employees *emp)

 

{

 

printf("Enter name: ");

 

gets(emp->name);

 

printf("Enter ssn: ");

 

for(int i =0; i <9; i++)

 

scanf("%d", &emp->ssn[i]);

 

printf("Enter birth year: ");

 

scanf("%d", &emp->yearBorn);

 

printf("Enter salary: ");

 

scanf("%d", &emp->salary);

 

}

 

 

 

// function to create a pointer of employee type

 

struct employees *createEmployee()

 

{

 

// creating the pointer

 

struct employees *emp = malloc(sizeof(struct employees));

 

// function to read the data

 

readEmployee(emp);

 

// returning the data

 

return emp;

 

}

 

 

 

// function to print the employee data to console

 

void display(struct employees *e)

 

{

 

printf("%s", e->name);

 

printf(" %d%d%d-%d%d-%d%d%d%d", e->ssn[0], e->ssn[1], e->ssn[2], e->ssn[3], e->ssn[4], e->ssn[5], e->ssn[6], e->ssn[7], e->ssn[8]);

 

printf(" %d", e->yearBorn);

 

printf("\n$%d.", e->salary);

 

}

 

 

 

// function to free the memory of the employee pointer

 

void releaseEmployee(struct employees *e)

 

{

 

free(e);

 

}

 

 

 

// main method

 

int main()

 

{

 

// creating the employee

 

struct employees *emp = createEmployee();

 

// printing the information

 

display(emp);

 

// free the memory

 

releaseEmployee(emp);

 

return0;

 

}

This expands the previous work to enable handling multiple employees. You will do this
by maintaining a global array of pointers to employees.
1) Define a global variable Emps that is an array of pointers to employee structs.
2) Change your createEmployee function to add the new employee to the Emps array. It
should place it in the first slot that contains a NULL.
3) Write a listEmployees function that will call your display function on each employee in
the array.
4) Change main to have a loop that looks for user commands.
• If the user types HIRE, you should call createEmployee.
If the user types LIST, you should call listEmployees.
• If the user types QUIT, you should exit the loop, which will then cause the
program to exit.
5) Write a findEmployee function that takes a string parameter and returns the
employee pointer with that name or NULL if no such person exists.
Change main to add a FIND name command that will find and display a single
employee.
