Thread: PHONEBOOK in c

hi! i'm new here and i'm a newbie at this programming and stuff..Our project is to create a phone book in pure c language and that it can add, view, search, delete, and edit entries. My problem is that I don't know how to search the name then view the details instead in our codes, when you search, you need to input its contact number and that just kills the use of phone book.<br>

We have the codes but it's not in pure c language, it has c++ codes.We are doing this by pair and most of the codes here are from my classmate I only did a tadbit of editing and debugging. Some also are from the internet. Help please?

Code:

#include<iostream>
#include<string.h>
#include<iomanip>
#include<stdio.h>
#include<conio.h>
#include<ctype.h>

Code:

#include<iostream> /* C++ */
#include<string.h> /* C */
#include<iomanip> /* C++ */
#include<stdio.h> /* C */
#include<conio.h> /* C, compiler specific, only for gotoxy type stuff */
#include<ctype.h> /* C */

If you want "pure C++" meaning "written in C", then lose everything with the comment /* C++ */. If you want "pure C" meaning standard C, then get rid of everything without the comment /* C */.

Then fix your indentation.

Code:

while(!feof(Patfile)&& found==false)
{
fscanf(Patfile,"%d%s%s",&cntct,&name,&address);

...

if(!feof(Patfile))
{
system("cls");
cout<<" \nLIST OF CONTACTS";
display();
while(!feof(Patfile))
{
if(fscanf(Patfile,"%d%s%s",&idno,&name,&address)>0)
cout<<setw(15)<<idno<<setw(25)<<name<<setw(25)<<address<<"\n";

...

while(!feof(Patfile))
{
if(fscanf(Patfile,"%d%s%s",&idno,&name,&address)>0)

...

while(!feof(tempPatfile))
{
if(fscanf(tempPatfile,"%d%s%s",&idno,&name,&address)>0)

...

while(!feof(Patfile)&&found==false)
{
if(fscanf(Patfile,"%d%s%s",&idno,&name,&address)>0)

Why it's bad to use feof() to control a loop

r2r has pretty much nailed this IMO. No doubt the OP is already looking for another forum to dump this crap on, rather than buckling down to some actual work.

A few suggestions for the start of the program:

Code:

#include<string.h>
#include<stdio.h>
#include<conio.h>
#include<ctype.h>
#include <time.h> 
 
//function prototypes
void menu(void);
int addRecord();
void viewAllRecords();
void viewOneRecord();
void display();
void deleteRecord();
void editRecord();
void sort(); //sort through an index maybe?


struct record {
   int idno;
   char name[25];
   char address[25];
   char phone[8];
   int code;    //area code
}rec1;



int main(void) { 
   FILE *Patfile;
   FILE *tempPatfile;
 
   int a, id;
   bool found;
    
   system("cls");
   menu();

   return 0;
} //end of main
 
void menu(void) {
   int choice=0, i, y;
 
   printf("\n\n\n\n\n\n\n\t\t");
   for(i=0; i<50; i++) {
      printf("*");

   printf("\n\n\n\t\t\t\t WELCOME\n\n\n\t\t");
   for(a=0; i<50; i++){
      printf("*");

   while(choice!='E') {
      //   system("cls");
      menuDisplay();
      printf("\nType the letter of your choice: ");
      scanf("%c", &choice);
      choice = toupper(choice);
   
      switch(choice)    {
         case 'A':{addPatient();break;}
         case 'B':{viewRecords();break;}
         case 'C':{deleteRecord();break;}
         case 'D':{editRecord();break;}
         case 'E': { gotoxy(1,20);
            for(y=20;i<22;y++)  {  //clear an area on screen
               gotoxy(1,y);
               for(i=0;i<2;i++)
                  printf("                                        ");
            }
            gotoxy(36,21);
            printf("*Goodbye*");
            Sleep(500);  //1/2 of a second, not 500 seconds ;)
            break;
         }    
         default: { printf("Please re-enter that choice\n"); 
            sleep(500);
         }
      }
   }
}
void menuDisplay(void) {
   printf("\n\t\t\t P O E B E  and  J A I' S");
   printf("\n\n\n\t\t\t\t Phonebook");
   printf("\n\n\n************************************");
   printf("********************************************");
   printf("\n\nC H O I C E S");
   printf("\n- - - - - - - - - - - - - - -");
   printf("\n[A] ADD Contact");
   printf("\n[B] VIEW Contacts");
   printf("\n[C] DELETE ONE Contact");
   printf("\n[D] EDIT A Contact ");
   printf("\n[E] EXIT");
   printf("\n- - - - - - - - - - - - - - -");
}

You've put together a lot of the code that you could use, but now you need to adapt it to ONE program, and take care of all the details. It's time to review your books or notes, and work with C, much more directly. Cobbling together code, can only go so far - and it won't be far enough -- never is.

Good luck with your assignment.

Maybe this is an example of extreme-agile programming!
