My program is a very simple address book program. The program works but i don't know how to make it display the same names. Like for example, the name "Mark Lee", if there are more than one Mark Lee, i would like to display all of those Mark Lee w/ its corresponding address & telephone no. How do i do that? What do i have to change in my program? I'm really very confused.
This is what my program looks like right now.
#include <stdio.h>
#include <conio.h>
#include <string.h>
#include <stdlib.h>

printf("\nb. Search and Edit a Record");
printf("\nc. Search and Delete a Record");
printf("\nd. Display all Records");
printf("\ne. Exit from the program");
printf("\n\nEnter your choice: ");
scanf(" %c",&choice);
return choice;
