Greetings everyone,

I need to make program in c language, here is a program that i made in the past but the instructions request 10 prototype functions and 6 types of entries (2 arrays, 3 integers and 2 doubles) for the structure.

Futhermore, there should be two prototypes (int search(purse list[],int *count,int id) and int display(purse list[], int *count, int loc)) wont be included in the char menu function, these functions below willl be called in both void deleteEntry(purse list[], int *count) and void addEntry(purse list[], int *count).

//searches the list by id and returns the index, if there is a match or returns 100 if there is no match (the maximum size of the list is 50)

//three arguments: list, number of items, id

int search(purse list[],int *count,int id);

//displays the ids in the list, gets the id from the user and returns it

int display(purse list[], int *count, int loc);

here are the instructions:

Here is my code:

#define _CRT_SECURE_NO_DEPRECATE

#include

#include

#include

#define MAX_ENTRIES 40

//hardcodes six entries

typedef struct {

//1-int called id

int id;

//2-char array called name

char make[20];

//3-char array called brand

char model[20];

//4-int called stock

int stock;

//5-double called cost

double cost;

//6-double called price

double price;

} purse;

//runs the menu and gets the user choice

char menu();

//prints the contents of the list onto the screen

void initializeEntries(purse list[], int*count);

//prints a report to a file /*declare the file pointer, connect to the file and close the file pointer all inside this function*/

void createReport(purse list[], int *count);

//adds an item to the list

void addEntry(purse list[], int *count);

//displays the ids in the list, gets the id from the user and returns it

void display(purse list[], int *count);

//searches the list by id and returns the index, if there is a match or returns -1 //three arguments: list, number of items, id

void clearRecords(purse list[], int *count);

//removes an item from the list //takes three arguments, the list, the number of items and the location

void deleteEntry(purse list[], int *count);

//updates the sale price//takes three arguments, the list, the number of items and the location

void update(purse list[], int *count);

int main()

{

//Declare variables

purse list[MAX_ENTRIES];

char Choice;

int count = 6;

initializeEntries(list, &count);

//Greets the user

printf("Hello and welcome. This program helps you create an inventory for Exotic Car Dealership. ");

printf("To get you started, 6 cars have already been entered. ");

//while loop for selecting menu options

while (1)
