this program has information about customers. this program has to perform the following functions.
- display list of all customers
- search by name
- search by id
- display list of customers having credit limit above 5000
- add new customers

i am unable to compile the program. here are the codes. can anyone fix it?

#include <stdio.h>
#include <conio.h>
#include <string.h>
#define MAX=999
int i;
int id;

struct customer {
 char custID[20];
 char name[50];
 char address[80];
 char tell[15];
 float credl; 
};
int add_Name ();
int menu_Display ();
int get_Menu ();
int get_Option ();
int cust_id();
 int cust_Name();


int main()
{
    
    menu_Display ();
    get_Menu ();
    get_Option ();
    
    getch();
 return 0;
 
}
int menu_Display () {
     int choice=0;
     while (choice!=6) {
           get_Menu ();
           choice = get_Option();
           }}
int get_Menu (){

And you create all_names out of nowhere in two of your functions

It doesn't really matter _that_ much, but this is more of a C program than a C++ one :)

Agreed. Moved.

this is the question

a software company has requested you to implement a customer information system that will keep
up to a maximum of 200 customer data. the customer information to be kept is
1. customer ID[20]
2. Name[50]
3. address[80]
4. telephone number[15]
5. credit limit

yor are requird to develop a c program that has a customer structure and an arra called customers.
the customer information system allows the user to
a. insert new customer using the sequential id.
b. search for a particular customer by ID.
c. search for a particular customer by name.
d. display a list of all customrers.
e. display a list of all customers having a credit limit above 5000

Again where is all_names coming from it's not anywhere in your code, that's the main thing that stands in the way of it compiling.
