error: 'count' was not declared in this scope & error: 'Pals' was not declared in this scope

Question

I try to make a program like the one in this book and write it the same

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <string.h>

int count;
int Pals;

int search()
{
char querystring[50];
int choice;
int d,m,y;
int i=-1;
printf("1. Search by name");
printf("2. Search by phone");
printf("3. Search by email");
printf("4. Search by birthdate");
printf("Enter you choice [1-4] :");
scanf("%d",&choice);
switch(choice)
{
case 1:printf("Enter name to search :");
fflush(stdin);
gets(querystring);
for(i=0;i<count;i++)
if(strcmpi(Pals[i].name,querystring)==0)
break;
break;
case 2:printf("Enter phone to search :");
fflush(stdin);
gets(querystring);
for(i=0;i<count;i++)
if(strcmpi(Pals[i].phone,querystring)==0)
break;
break;
case 3:printf("Enter email to search :");
fflush(stdin);
gets(querystring);
for(i=0;i<count;i++)
if(strcmpi(Pals[i].email,querystring)==0)
break;
break;
case 4:printf("Enter birthdate to search :");
scanf("%d%d%d",&d,&m,&y);
for(i=0;i<count;i++)
if(Pals[i].bday.day == d && Pals[i].bday.month == m && Pals[i].bday.year == y)
break;
break;
}
return i;
}

Answer 1

You should declare the variable count and Pals(array) in the beginning of your code, in the function search, like the other variables.

Answer 2

The problem is:Pals. Did you declare the variable Pals like array;

Answer 3

What is the Pals; Is it a number, a character, an array? You use it to the if in every case.

Answer 4

Ok, maybe you should look closely the
book you have. I can't see it. Maybe is something else.

Answer 5

I think that the best is to search and understand by yourself and not get the answer by me.

Answer 6

Sorry in advance, I don't understand what should I do to make the program run?

Answer 7

what I see and I understand a little bit, the use of each case is to input a name, mobile number, email, and birthday to find out if there is any

Answer 8

now error: subscripted value is neither array nor pointer nor vector

on this line
if(strcmpi(Pals[i].name,querystring)==0)

Answer 9

may I give the book for you to see? I'm very grateful for the help
