    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>
     
    using namespace std;
     
    void menu();
    void addPatient();
    void viewRecords();
    void viewAllRecords();
    void viewOneRecord();
    void display();
    void deleteMechanism();
    void editRecord();
    void menuDisplay();
    void viewOneMechanism();
    void deleteRecord();
    void question();

    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.

    Our project is to create a phone book in pure c language
    Code:
    void addPatient();
    Maybe you should consider writing your own code, rather than trying to cobble together your project from various disparate Internet sources and dumping it here to try to get us to make it work so you can get a good grade you don't deserve.

    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.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    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!
