Search function in CRUD with C - c

Question

I'm making a contact book in C and I've already done the parts of registering contact, listing all contacts and deleting a contact, but I need to elaborate the part of searching the contact, and also searching contacts that start with a given string, but I'm not succeeding... I'll leave my code below to see if anyone can help me identify where I'm going wrong:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_LENGTH 50
typedef struct
{
char name[MAX_LENGTH];
char number[MAX_LENGTH];
int bd;
char bdm[MAX_LENGTH];
} ContactBook;
void ListContacts(ContactBook **c, int quant)
{
int i;
printf("\n List of contacts: \n");
for (i = 0; i < quant; i++)
{
printf("\t%d = birthday: %2d month %s\t name: %s \t number: %s\n", i + 1, c[i]->bd, c[i]->bdm, c[i]->name, c[i]->number);
}
}
int addContacts(ContactBook **c, int quant, int size)
{
if (quant < size)
{
ContactBook *new = malloc(sizeof(ContactBook));
printf("\nenter contact name: ");
scanf("%s", new->name);
printf("\nenter number: ");
scanf("%s", new->number);
printf("\nenter the birthday ");
scanf("%d", &new->bd);
printf("\n enter the month birthday: ");
scanf("%s", new->bdm);
c[quant] = new;
return 1;
}
else
{
printf("\n full list.\n");
return 0;
}
}
int deleteContact(ContactBook **c, int quant)
{
int id;
ListContacts(c, quant);
printf("\n\t Enter the id you want to delete: \n");
scanf("%d", &id);
getchar();
id--;
if (id >= 0 && id < quant)
{
free(c[id]);
if (id < quant - 1)
{
c[id] = c[quant - 1];
}
return -1;
}
else
{
printf("\n\t wrong code;\n");
return 0;
}
}
void SearchContact(ContactBook **c, int quant)
{
int i;
char searchedName[30];
for (i = 0; i < quant; i++)
{
printf("\n Search name: \n");
scanf("%s", searchedName);
getchar();
if (strcmp(searchedName, c[i]->name) == 0)
{
printf("the name: %s was found", c[i]->name);
}
else
{
printf("name not found");
}
}
}
int main()
{
ContactBook *contacts[50];
int option, size = 50, quant = 0;
do
{
printf(" \n\t0 - exit\n\t1 - register contact\n\t2 - Remove contact\n\t3- List contacts\n\t4- Search contact\n\t");
scanf("%d", &option);
getchar();
switch (option)
{
case 1:
quant += addContacts(contacts, quant, size);
break;
case 2:
quant += deleteContact(contacts, quant);
break;
case 3:
ListContacts(contacts, quant);
break;
case 4:
SearchContact(contacts, quant);
break;
}
} while (option != 0);
return 0;
}
