Question

//Below is the starting code for this homework assignment// 



#include <stdio.h>

 

struct employees

{

    char name[20];

    int ssn[9];

    int yearBorn, salary;

};

 

struct employees e = {"kim deen", {1,2,3,4,5,6,7,8,9}, 1998, 35000};

 

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);

}

 

int main()

{

    display(&e);

 

    return 0;

}

Although it will no longer be used, please leave the earlier global variable with the initialized data in the program.
1. Write a readEmployee function that takes a pointer to an employee struct and fills in the details. It should prompt the user for
each field, then read the data from the user and store it in the struct passed in.
Be careful to appropriately copy the string values. You do not need to worry about checking for buffer overflow.
2. Define a createEmployee function that will allocate the memory for an employee structure and return it. Before returning the
pointer, it should call your readEmployee function to fill in the data.
3. Change your main function to call createEmployee and hold the pointer returned. This pointer should then be passed into your
display function.
4. Write a releaseEmployee function that will free all the memory allocated for the employee whose pointer is passed in as the
argument.
5. Modify main to call releaseEmployee after the display call. You main function should now include a pointer variable
declaration, a call to createEmployee, a call to display and a call to releaseEmployee.
